Best Flip Up Glasses Reviewed & Rated for Comfort

Sunglasses can be key to a successful hunt. Protection from the sun and some hi-def sight capabilities can be the difference between spotting your game and missing it completely. But you also don’t need to crack open your wallet for an expensive pair of Oakleys or sports sunglasses, especially if you wear glasses yourself. You still need to be able to see without breaking the bank for prescription shades.

 Criteria Used in Choosing the Best Flip Up Glasses

Before you can evaluate a pair of flip-up sunglasses any further, you will need to make sure that the will work with your glasses. If the flip-up glasses do not fit your glasses, then it will not matter how good they are if what sort of lenses come with the glasses because you will not be able to wear the flip-up glasses that you are looking at. For this reason, you will need to make sure that a pair of flip-up glasses works with your glasses in the first place and that they are comfortable while you are wearing them. Otherwise, you will need to consider looking at a different pair of flip-up glasses.

Compatibility and Comfort

One of the first things that you will need to check is if the flip-up glasses will attach to your frames. Flip-up glasses has a clip on the top center of the glasses that are used to attach the flip-up glasses to your existing glasses. Of course, everyone has different frames for their glasses and some frames are thick while other frames are thin. You will need to make sure that you can securely attach the flip-up glasses to your frames in order to make sure that they are useful. Once you have checked that the glasses can be attached to your frames, you will need to make sure that they remain tight on your glasses. The flip-up glasses should not tilt on either side when you move your head or adjust your glasses. They should also maintain their position when you flip them up and put them back down over your glasses. If your flip-up glasses do not hold their position while you are using them, then there is a chance that they might fall off of your glasses when you need them.

 

You should also check that the flip-up glasses match the shape of your lenses as well. You will not want to wear a pair of flip-up glasses that have lenses that are way too large or way too small for your regular glasses. Sunglasses lenses that are too small will not provide you with sufficient eye protection while glasses that are too large will be bulky and could feel heavy. In both cases, the flip-up glasses will look out of place and you will look silly while you are wearing them. The same principle is true for the shape of the lenses as well. The shape of the lenses on the flip-up sunglasses should closely match the shape of your lenses for your regular pair of glasses. Once again, you will not get proper sun protection if the shape of the lens is off and you will look abnormal while you are wearing the sunglasses. For these reasons, you will want to look for a pair of flip-up sunglasses that have a lens shape that is similar to your existing glasses. Most glasses have lenses that are shaped in a square or round cut, so it should not be too hard to find a pair of flip-up glasses that will match your regular glasses.

 

After you have found a pair of flip-up glasses that fit your glasses, you will need to make sure that you feel comfortable while you are wearing them. Flip-up glasses will add weight to your existing glasses and for some people, the extra weight can result in pressure on the nose and the ears. You will need to make sure that you are not sensitive in these areas when you are considering flip-up glasses so that they feel comfortable while you are wearing them. You should also look for lightweight flip-up sunglasses as this will help reduce the pressure that you will feel on your face while you are using the flip-up sunglasses. It is also possible that you will need to have your glasses adjusted so that they do not slide around on your face while you have flip-up glasses attached to them. Once again, your glasses may fit fine without having flip-up sunglasses but they may start to slide or sag on your face when they have the extra weight attached to them. You can either adjust your glasses accordingly or look for a pair of flip-up glasses that weighs less.

 

Compatibility and comfort will be two things that you will want to check when you are picking out a pair of flip-up sunglasses. It will make no difference what the glasses can do for your vision or high quality they are unless you are able to wear the flip-up sunglasses in the first place. One of the first things that you will need to check is to make sure that the flip-up sunglasses will work with your regular frames. That means they need to attach to your glasses and look correct while they are on. Then you will need to make sure that you feel comfortable while you are wearing the flip-up sunglasses.

 

Lens Color

You will most likely notice that flip-up sunglasses have different colors of lenses. The color of the lenses is not primarily about different styles and preferences but is instead about functionality. White light has seven different colors and different colors of lenses will affect how you see in the light. When you are picking out a pair of flip-up sunglasses, you will want to know about the different colors of lenses that are available and how they will protect your eyes and help you see in the sunlight. The more you know about each color, the better job you will be able to do when picking out a pair of sunglasses that is best suited to your needs.

If you plan on wearing your glasses in bright and sunny conditions, then you should look for a pair of sunglasses that have grey colored lenses. Grey does not affect your ability to see colors, but it will shade and protect your eyes from the bright light that you typically see in clear summer days or on the beach. This makes grey and ideal color for people who are planning on spending time on the water, such as when you go boating or driving in bright sunshine. You may also want to use grey when you are in the snow on a clear day because snow reflects all of the light back into your eyes. A good rule of thumb is that whenever you are in bright and clear conditions, you will want to look for sunglasses that are grey to offer you the best sun protection without distorting your ability to see colors.

Of course, we are not always in bright and clear weather. There are plenty of times where we are outside in bright and overcast weather which can cause eye strain for some people. If you think you will be in this sort of weather more often than not, then you may want to consider looking for a pair of sunglasses that have a brown lens. The color brown will filter out blue light which will help provide you with more color contrast on these sort of days. It also will provide your eyes with more shape definition which will give you the ability to see better when it is bright, yet overcast at the same time. Shallows fishing when the conditions are bright outside is a good use case for brown lenses, but there are plenty of other times where you may choose to wear a pair of sunglasses that have brown lenses.

Copper colored lenses are a shade that is better suited for hazy days where the lighting is variable. When you are outside in the hazy sunshine or when it is overcast outside, you may start to squint and strain in order to see well. Copper lenses will filter out light colors that cause you to squint and strain when you in these weather conditions which can help you see better. By reducing squinting and straining, you are less likely to experience headaches or other pain that is associated with eye strain. Copper may also allow objects to look brighter and sharper. Driving is a good application for wearing copper colored sunglasses since they can be worn year round and will help you see better while you are on the road. You may also want to wear copper color sunglasses in the fall or winter seasons as well due to the weather conditions in those times of the year.

Yellow is the final color of lenses that you will see when you are shopping for a pair of sunglasses. This color is best suited to days that are dull, misty, or rainy because it will enhance yellow light. Yellow light is the primary color of light that is produced by the sun and it is what our eyes are best adapted to see. By enhancing yellow, you will see sharper when you are in lower light conditions. This makes yellow a great choice to reduce glare from car headlights, as well as reducing light from the lower angles of a winter sunset. Yellow will also reduce light exposure without making shadows overly dark which is another reason it is great for lower light conditions.

Every pair of sunglasses has different colored lenses and each color is best suited for a specific set of conditions. This doesn’t mean that you can’t use a color in conditions that it isn’t tailored towards, but rather you will get the best performance when the color of the sunglasses is matched to the conditions it is meant to used in. For grey colored lenses, this means they will perform their best under the bright light on clear days. You should always think about the conditions that you plan on using your sunglasses in and look for a color of lenses that are best matched to those conditions. This will allow you to see your best while you are using your flip-up sunglasses.

UV Protection and Intensity

A good pair of flip-up sunglasses will need to protect your eyes from the sun. However, you need to think about what this means when you are picking out a pair of sunglasses. The sun emits a lot of different types of light and some sunglasses only protect your eyes from certain kinds of light while other and more expensive sunglasses help protect your eyes from a variety of harmful light sources. You will need to think about how much protection from the sunlight you want from your sunglasses and choose accordingly. Some people will only need or want a pair of sunglasses that shade their eyes while other people want a pair of sunglasses that protect their eyes from all kinds of harmful light. Knowing about the different kinds of light protection will help you pick a pair of sunglasses that is best for your unique pair of eyes.

Most people are familiar with ultraviolet (UV) light because this is the spectrum of sunlight that causes sunburns. Just like UV light damages our skin, UV light will also damage the corneas and retinas in our eyes which leads to a loss of vision later in our lives. There are plenty of pairs of sunglasses that block UV light and this is something that you will want to consider when you are looking for UV protection for your eyes. Just like your skin will be healthier if you protect it from UV light, so will your eyes. Sunglasses offer different UV ratings which will help guide you selecting a pair of glasses that will protect your eyes from UV damage. The higher the UPF rating is on the sunglasses, the better job they will do at blocking UV light from your eyes. There are sunglasses that can completely eliminate your exposure to UV light so if this is a concern for you, then you should look for sunglasses that completely block UV light.

When most people think about sunglasses blocking light, they are thinking about reducing the brightness of the light. Brightness is another word for intensity and the great the intensity of the sunlight, the brighter it will look to your eyes. As the eye receives more light, the pupils will close to block light from entering your eyes. However, your pupils can only close so far and once they have closed as far as they can go, you will need to start squinting in order to block too much light from entering your eyes. Squinting causes eye strain and many people will experience headaches or other conditions related to eye strain. Sunglasses help filter light from reaching your eyes which reduces the intensity of the light. Reducing light is important because too much light entering your eyes will damage the retina which will lead to a loss of vision. This is why we are told to never look at the sun directly or stare at someone who is welding.

The shade of the lens is what reduces the intensity of the sunlight. This is why you will find sunglasses that have extremely dark lenses for protecting your eyes from bright light (think welding goggles) or lenses that are only slightly tinted to protect you from a little bit of extra light. You will need to look for a pair of sunglasses that have the proper shade of tint in order to reduce the amount of light that is exposed to your eyes. You should choose sunglasses that have dark colored lenses when you are in conditions that have bright light while you can go with sunglasses that have less tint for when you are in areas where you only need a little protection from light intensity. General purpose sunglasses may have a medium shade of lens that is not too dark or too light so that you can wear the sunglasses in a wider range of circumstances as well. There are also sunglasses that can adjust the shade of the lens depending on the intensity of the light as well. These are often called transition lenses or by another brand or trademark.

 

Your eyes need protection from UV light and intensity which is why you will need to think about these two factors when you are picking out a pair of sunglasses. UV light is damaging to your corneas and your retinas and too much exposure to it can lead to a loss of vision. If you are concerned about UV light, then you will want to look for a pair of sunglasses that offers you UV protection. The higher the UV protection, the healthier your eyes will be while you are wearing the glasses. Sunglasses also protect you from the intensity of the light (brightness) by having darker lenses for bright light and only slightly tinted lenses for just a little bit of light protection. You will always want to think about what sort of light conditions you will be in when you are picking out a pair of sunglasses and make sure that they are suitable for your needs.

 

Glare Protection

 

At some point in time, you have seen light reflected off of a surface such as water, snow, or sheet metal where the light ends up being extremely intense and causes you to squint or see spots after you have looked at the light. This is called glare and glare can be uncomfortable to our eyes or it can even cause permanent damage to our eyes. When you are looking at a pair of flip-up sunglasses, you will want to make sure that they have protection against glare so that you do not experience damage from glare. Depending on the technology that you have in your sunglasses, you may be able to reduce glare completely which will offer you the best protection from glare. At a minimum, you should consider getting a pair of sunglasses that are polarized.

 

All light is polarized, which means that light has a direction. Light can enter your eyes vertically or horizontally as well as every angle in between. When we are talking about polarized sunglasses, we are talking about sunglasses that block light that is coming at our eyes from a horizontal or almost horizontal direction. This is because the horizontal light is the most common direction of glaring light that you will often see if you are looking at a body of water, snow or the highway. Polarized sunglasses work by only allowing light that is fixed at a vertical angle from passing through the lenses of the sunglasses and entering our eyes. By only allowing vertical light, you are much less likely to experience seeing a blinding glare of light when you are looking at a distance. This is why polarized sunglasses are popular with people who spend time on the lake or truck drivers who spend a lot of time looking at the road.

 

However, many polarized sunglasses are not polarized and are falsely advertised as being polarized so you will need to check that the pair of flip-up sunglasses that you are looking at is in fact polarized. You can check if a pair of sunglasses is polarized very easily so it is not difficult to tell if someone is selling you a bad pair of sunglasses. You check the polarization of the sunglasses by finding a reflective surface to look at while you are looking through the sunglasses. You will want to look at the reflective surface through the glasses as you rotate them from horizontal to a vertical direction. If you do not see any change in how the surface looks as you rotate the glasses, then the glasses are not polarized and they will not protect your eyes from horizontal glares. On the other hand, if the amount of light you see changes dramatically as you rotate the glasses, then they are polarized and can be counted on to protect you from glares while you wear the glasses.

 

There is another source of glare that you may experience while you are wearing your sunglasses. Back-glare is a type of glare that is caused by light hitting the back of your sunglasses and then reflecting back into your eyes. Just like glares from lakes, streams, and roadways, back-glare is also harmful to your eyes because it increases the intensity of the light that is getting directed into your eyes. You can reduce or eliminate back-glare by looking for a pair of sunglasses that has an anti-reflective coating that is applied to the back of the lenses. The anti-reflective coating (AR) is a thin coating that is only the thickness of about 1/4 of a light’s wavelength and when it has been applied to the backside of the sunglasses, it has a refraction index that is between air and glass. This causes the intensity of the light that comes from the outside of the AR film and the light from the glass lenses to be equal due to a destructive interference between the light waves. The result is that you are less likely to experience glare from the backside of your sunglasses which means that you will be able to see more comfortably.

 

Protection against glare should be a concern that you will want to take a look at when you are picking out a pair of flip-up sunglasses. There are two ways that sunglasses can protect your eyes from glare which are having polarized lenses that block horizontal glare and AR coating which reduces glare caused by light reflecting from our lenses. Glare can make it hard for you to see and will cause you to squint when you are exposed to it. Not only can glare be uncomfortable for your eyes, but it can also damage your eyes if the glare is too intense. For this reason, you will always want to look for a pair of sunglasses that will eliminate or at least reduce the glare that you will experience while you are outside.

 

Quality

 

Quality is an issue almost every consumer is concerned about and for good reasons. When you are purchasing a pair of flip-up sunglasses, you are trusting the safety of your eyes to your glasses. This is one of the most important reasons for you to look for a high-quality pair of sunglasses because it will make the difference in how well you can see. Of course, another reason why you will want quality in your sunglasses is that a high-quality pair of sunglasses will last longer than a low-quality pair of glasses. That means you will save money in the long run because you will not have to keep repairing or replacing your flip-up sunglasses and can just keep using the pair that you have until you are bored with them or they finally wear out.

 

One of the things that you will want to check on the flip-up sunglasses is the frames. The frames are the pieces that hold the lenses in place and also connect the flip-up glasses to your main glasses. You will want to look for frames that are durable and do not bend or break easily. Flip-up glasses can easily be forgotten about and this can result in your placing them down on something and forgetting about them. For example, you may place a pair of flip-up sunglasses in a beach bag and then set something on top of the beach bag. If the glasses have weak frames, they may bend or break completely which would ruin them and make them unusable. On the other hand, the frames may wear out quickly which means that the glasses will no longer be able to attach to your main pair of glasses properly. This can turn into the glasses getting wobbly and tilting easily or it could mean that they fall off of your glasses when you do not expect. For these reasons, you will need to make sure that your flip-up glasses have strong frames so that they last and are usable for a long time.

 

Once you have taken a look at the frames, you will want to turn your attention to the lenses. It is the lenses that you are trusting to protect your eyes from harmful light so it is a good idea that you make sure that you have purchased flip-up sunglasses that are made with high-quality lenses. One of the first things that you should check is if the glasses have fraudulent advertising. For example, many sunglasses are sold as polarized sunglasses but they are not polarized at all when you test them. If there is any sign of the glasses being falsely advertised, then you should not purchase the sunglasses as they will be other things about the glasses that are also presented falsely. False advertisement of sunglasses and flip-up sunglasses is a common problem so you will need to be on the lookout for this.

 

If you believe that the glasses are authentic, then you will want to look at the lenses to make sure that they are good quality lenses. Cheap flip-up sunglasses have plastic lenses which will scratch and break easily. They also do not absorb impact very well so you will need to be on the lookout for cheap lenses that are made from plastic. It is unlikely that you will see flip-up sunglasses that have glass lenses due to weight, but if the lenses are made from glass they will be more resistant to scratching which is a good characteristic. The best kind of sunglasses lenses is polycarbonate lenses, which is a high-quality plastic material that is strong like glass but is also lightweight. Polycarbonate lenses have the best protection against breaking and scratching.

 

You will also want to look for things on the lenses such as protection against UV light and polarization. These technologies block harmful light from entering your eyes which will help preserve your vision. They also make the glasses more comfortable to wear since you will have less need to squint. You should also make sure that the lenses have the correct shade for the area that you plan on being in and also have the correct color lenses. All of this will help ensure that you have picked out a high-quality pair of flip-up sunglasses.

 

When you pick out a pair of flip-up sunglasses that are well made, you will be happier with the glasses in the long run. High-quality sunglasses will protect your eyes from damaging light and they will also resist breaking. That means that you will be able to wear your sunglasses longer between replacing them. The better job you do with determining the quality of the sunglasses, the better job they will do of making sure you have a great time in the sunshine.

FAQs

Frequently Asked Questions

Q: Is there a reason to wear flip-up sunglasses at night?

A: Functionally speaking, there are no typical reasons to wear sunglasses after dark because there is less light after dark and therefore your eyes do not need protection from the light. Some people may wear sunglasses at night or indoors as a fashion statement but this has nothing to do with how well the flip-up sunglasses will protect your eyes. You may want to wear flip-up sunglasses if a doctor dilates your eyes but this is only because your eyes are not blocking light while they are dilated.

Q: Why use flip-up sunglasses?

A: Flip-up sunglasses are useful because they attach to the glasses that you already wear. When you need protection against the light, you flip them over your lenses and when you no longer need them, you can flip them up. This offers an advantage over regular sunglasses where you need to keep changing pairs of glasses and clip-on glasses that can get lost or broken more easily. Out of the three options, flip-up sunglasses are the most flexible choice.

Q: Why should I wear sunglasses when it is cloudy?

A: Sunlight will not be as intense when it is cloudy or hazy out, but you are still going to be exposed to UV light which can damage your eyes. Your eyes may also be sensitive to certain colors of light which are more prevalent when you are in such weather. As long as you can see OK with sunglasses, it may be a good idea to wear them to protect your eyes from glares, UV, and certain frequencies of light.

Q: Can flip-up sunglasses be repaired when broken?

A: This will depend on the damage that was done to the glasses. For example, you may be able to bend a frame back to its original position, replace a lens, or tighten a screw on the sunglasses. Other sorts of damage cannot be repaired such as if the frames break completely and are too thin to join back together. There are also times where it costs more to fix the sunglasses than to replace them so you will need to consider this as well.

Q: Why should I avoid knock-off sunglasses?

A: Knock-off sunglasses are glasses that masquerade as an expensive brand of sunglasses. They are normally an inferior product which is why you should not expect them to protect your eyes from sun damage and they are normally sold at a price that is below the price of the glasses that they are pretending to be but higher than the real value of the sunglasses. It’s one thing to purchase glasses at a fair price, but you should not pay a premium for sunglasses that are not real.
