When you wear prescription sunglasses, you can see well in the bright or cloudy sunshine whether you’re riding a bike, driving a car, or taking part in outdoor sports. They help shield your eyes from damaging UV rays. To help you choose the right pair of prescription sunglasses, your Carmel, IN optometrist wants you to understand the distinction between non-polarized and polarized prescription sunglasses.
Polarized sunglasses are created to improve colour perception and contrast sensitivity. They help decrease glare without completely obscuring your field of vision. Sports enthusiasts, particularly those who fish, boat, water ski, snow ski, and enjoy other outdoor activities that may be affected by the glare off snow or water, benefit from wearing polarized sunglasses. The ability of polarized prescription sunglasses to lessen the sharpness of reflections and glare off of smooth or wet road surfaces is also appreciated by drivers of motor vehicles. Polarized sunglasses may make it simpler for persons who have trouble seeing when driving through heavily illuminated regions at night or in traffic or when surrounded by bright street lamps and flashing signage.
If you work with LCD screens or don’t need or want greater glare protection, your eye doctor might advise non-polarized sunglasses. Images on LCD screens often get blurry or totally disappear while using polarized sunglasses at certain angles. To see clearly and effectively while operating heavy machinery, people should use non-polarized sunglasses rather than polarized ones. Non-polarized lenses will equally darken the objects in your field of view and are less expensive than polarized lenses, which will lessen your sensitivity to colour and contrast.
How to choose between polarized and non-polarized lenses
Both polarized and non-polarized lenses offer advantages, so your decision should mostly be based on your needs. Both guarantee healthy eyes to varying degrees, but polarized glasses work harder by design to safeguard your eyes, especially if you’re frequently exposed to bright sunlight. They also give colour enhancement, clarity, and strong contrast. If you don’t specifically want those qualities or don’t lead a lifestyle that calls for them, you can be satisfied with a pair of non-polarized sunglasses.
