Are Polarized Lenses Really Worth the Extra Money?
During sunny days, sunlight is reflected in multiple directions by various surfaces. Horizontal surfaces such as pavements, sandy beaches, and water surfaces reflect the rays horizontally thus producing a strong glare. Glare affects your vision by distorting colors, altering depth perception and causing temporary blindness. You can stop or minimize glare if you use appropriate sunglasses. There are thousands of sunglass models to choose from. They also come in various styles and frame designs to suit all types of face shapes. But when it comes to lenses, you can only choose between polarized and non-polarized lenses.
Non-polarized ones don’t filter reflected rays; they just minimize the amount of light reaching your eyes. This means that you still get reflected rays with glasses on. Dark-tinted models also don’t eliminate glare. In fact, those without UV protection are more harmful to your eyes. This is because they make the pupils dilate thus allowing more UV rays in your eyes. Excess UV rays can cause cataracts and other eye conditions.
Polarized lenses have an built-in filter that has been designed to block horizontal rays which cause glare. The lenses also minimize straining and eye fatigue caused by reflected rays. Eye fatigue is caused by constant contraction and expansion of the pupil to adjust to ever-changing light intensity. This problem usually causes migraines and headaches.
However, polarized lenses tend to be a little bit pricey as compared to non-polarized ones. Despite being expensive, more people are buying them. But are polarized lenses really worth the extra money? The answer is yes if you spend most of your time surfing, hiking, golfing, driving and doing other outdoor activities.
Let’s see some of the reasons why you might need polarized lenses.
1) They come in various color tints
When it comes to color tints, there are multiple color options to choose from. Cheap models have a generalized filter which works well in most lighting conditions. However, if you want lenses with superior filtering capability, invest in tinted models with special filters. Yellow lenses have been designed to filter blue-light spectrum waves which usually over-stimulate your eyes causing headaches, fatigue and straining. Rose lenses sharpen your contrast and focus in various lighting conditions thus reducing chances of having migraine. Gray lenses are the most common models since they filter all wavelengths evenly. Brown lenses are usually effective in cloudy days and bright light conditions. Finally, go for green lenses if you want maximum protection. Green models are superior since they are effective in extreme glare.
2) The lenses are perfect for driving
During hot, sunny days, sunlight is reflected by asphalt on road surfaces, hoods of cars, windows and other highly polished surfaces. Reflected rays cause dangerous glare which makes motorists strain to distinguish various objects on the road. The lenses promote safe driving since they block reflected light at certain angles.
However, certain polarized lenses react negatively to some windshield color tints. This means that you should check if the lenses are compatible with your windshield before buying. In addition, darkened models make it difficult to see in dark environments. The situation is even worse if you already have trouble seeing in low-light conditions.
3) They are good for snow skiers
The bright snow usually reflects a lot of light during sunny days. Most snow skiers find snow glare to be almost blinding, especially if there is no vegetation cover for miles. If you are a skier, these lenses can help you see clearly during bright days since they minimize snow glare.
However, experts claim that polarization and darkening effect of sunglasses might make it difficult for some skiers to distinguish details, especially when looking down. This is quite dangerous since a skier needs to distinguish between snow and patches of ice or moguls.
4) They are excellent for individuals suffering from photophobia
People that are sensitive to slight changes in light intensity are highly affected by glare. Individuals with this condition feel intense pain when they move in a bright environment. Prolonged exposure to light can worsen the condition and negatively impact their health.
Such individuals are usually prescribed photochromic lenses which automatically change color depending on the light intensity. The lenses lighten in low light conditions but gradually darken with increasing light intensity. The special lenses have been designed to eliminate harmful wavelengths present in sunlight, fluorescent light, and other light sources. This reduces migraines, headaches, eye fatigue, and other health problems.
Photochromic lenses are also polarized to eliminate reflected light. But if your old lenses are becoming ineffective in reducing glare, you don’t need to buy new glasses since you can just replace the lenses. In case you need new replacement lenses, you can buy them at thesunglassfix and improve your vision. Replacement lenses are usually as good as new original lenses in terms of optical clarity and minimizing glare.
5) They are perfect for biking
When cycling down the trail or road, you need to clearly distinguish between various objects to avoid accidents. The polarized glasses filter intrusive sunbeams thus improving your vision and overall performance. Such glasses are handy when traveling down the slope at high speeds because you need to be accurate to avoid hitting objects that can cause an accident. In addition, some lenses are thick enough to protect your eyes from dirt, sticks, rocks, and flying insects.
6) The lenses are handy when golfing
A golf course has light and dark patterns which you need to distinguish clearly to make accurate moves. The tinted lenses eliminate reflected light and enhance contrast. This allows you to make accurate putting even in bright sunlight.
7) Polarized lenses enable boaters to see clearly
Boaters encounter many challenges when navigating through water on a bright day. The movement of water and its mirror effect causes glare which prevents them from seeing through the water. This problem makes some boaters to hit rocks, logs and other objects underwater and this damages their vessels.
Polarized lenses have a vertical filter which blocks most of the reflected light from the water surface. The reduction of glare improves vision and boaters can see some objects underwater and avoid unnecessary collisions. The lenses also minimize reflected light form rocks and other boats in line of sight.
Horizontal glare can cause various eye problems which are expensive to treat. To prevent this problem, you need to wear glasses with polarized lenses during sunny days. Polarized lenses are worth the extra money because they are perfect for those who are sensitive to light and can protect your eyes when doing various outdoor activities such as driving, playing golf, biking, skiing, and boating.
