Depending on your lens and intended use, you may want to consider adding a scratch-resistant coating. High-index lenses offer a thinner, lightweight alternative for people with a high degree of nearsightedness , farsightedness or astigmatism. These lenses bend light in a different way and require less lens material to correct your vision. Choosing a lens material is far from the only way you can make a pair of Rx sunglasses your own.
Polarized, photochromic and gradient coatings help you further customize the function of your frames. Polarized lenses are excellent at reducing glare, making them a solid option for those who spend a considerable amount of time near water, snow or other reflective surfaces. People who fish, participate in summer or winter sports, or simply want to drive more comfortably on a sunny day may all be able to benefit from polarized Rx sunglasses.
Any type of polarized sunglasses can make it hard to see the backlit displays on devices like:. When possible, it can be a good idea to test photochromic lenses before you buy them, since some lens brands take longer to darken than others. Many lenses also have difficulty darkening inside vehicles or will not darken at all.
Gradient lens finishes usually have a darker shading at the top of the lens, compared to the bottom. Gradient lens coating can be useful for cutting the glare from a bright sky, with a clearer view lower in your field of vision.
For this reason, gradient lenses are popular for driving, since the unshaded bottom half allows a clear view of the dashboard. Double-gradient lenses, on the other hand, utilize a darker tint on the top and bottom of the lens, but a lighter one in the middle. Rx sunglasses can also have a reflective mirrored finish — thin layers of metallic coating on regular lenses.
These risks can be even more pronounced for children, since their eyes are more sensitive to UV and are exposed to about three times more radiation as the adult eye, according to the Vision Impact Institute.
Other people at risk for sun-related problems include those who spend long hours in the sun, have certain retinal disorders, have had cataract surgery, or take medications that increase sensitivity to light.
In fact, a study published in Optometry and Vision Science found that the effectiveness of UV filtering in sunglasses did not correlate with the price of the lenses. While countless brick-and-mortar stores offer high-quality Rx sunglasses with complete UV protection, you can get just as much browsing done from the comfort of your couch.

Major optical retailers like LensCrafters and VisionWorks also sell a wide selection of frame designs both online and in-store. And remember, you will need a valid vision prescription from an eye doctor to complete any orders.
If you have vision insurance , some or all of the cost of prescription sunglasses could be covered. These accounts allow people to set aside money for certain medical expenses without being taxed. Some plans may not include Rx sunglasses as part of their coverage. For more information about coverage and eligibility, check with your insurance provider.
