Do you need to wear contact lenses when your sunglasses because you are nearsighted? For many people, this can be a very troubling thing. In fact, it is not only a hassle, but can also easily affect your health-- Contacts can be annoying when you wear them with sunglasses. They may irritate your eye and cause discomfort. Contacts also make you more prone to eye infections, since grit, dirt, and other debris can get underneath your contacts an eye infection. This isn’t a problem with prescription sunglasses, though.

The lenses in Prescription Sunglasses can also feature a combination of different materials and coatings. 

Materials

Aside from standard plastic or glass materials, three of the most popular lens materials are Polycarbonate, Trivex, and High-index plastic.

In addition to standard plastic or glass materials, the three most popular lens materials are polycarbonate, Trivex, and high refractive index plastic.

Polycarbonate lenses use a strong and impact-resistant material, making them ideal for sports and other physical activities. These lightweight lenses are also 30% thinner than regular lenses.

Originally developed for military helicopter windshields, Trivex is also durable, but lightweight. However, compared to polycarbonate, Trivex lenses have less virtual distortion, resulting in a clearer view.

One disadvantage of polycarbonate and Trivex lenses is that they are prone to scratching. Depending on your lens and intended use, you may want to consider adding an anti-scratch coating.

High refractive index lenses offer a thinner, lighter option for people with high levels of nearsightedness, farsightedness, or astigmatism. These lenses bend light differently and require less lens material to correct vision.

Coatings

Polarized lenses are excellent at reducing glare and are a reliable choice for those who spend a lot of time near water, snow, or other reflective surfaces.

Photochromic lenses (also known as transition lenses) automatically darken in sunlight. In addition to offering the convenience of a single pair of sunglasses instead of two separate frames, their Rx lenses ensure that your eyes are never exposed to too much solar UV radiation.

If possible, it's a good idea to test photochromic lenses before you buy, as some lens brands take longer to darken than others.

Graduated lens surfaces usually have deeper shadows at the top of the lens than at the bottom. This can also be called a "single gradient".

The gradient lens coating effectively reduces glare in bright skies, giving you a clearer view where your field of vision is lower. For this reason, gradient lenses are popular when driving because the lower part of the dashboard can be seen clearly without shadows.

Rx sunglasses can also have a reflective lens finish - a thin metallic coating over the regular lens. These lenses reflect and reduce visible light, but still require adequate UV protection to protect the eyes from the sun's harmful rays.

Conquering Glare is the main reason why most people buy sunglasses. Glare can be problematic for anyone who is spending time in the great outdoors. Instead of struggling with it, you can wear prescription sunglasses. With polarized prescription lenses, patients can neutralize the glare which can be problematic.

Another benefit of wearing prescription sunglasses is keeping your sense of style intact. You can still sport a cool look as you benefit from the protection of prescription sunglasses. At the same time, many sunglasses have a more fashionable rim shape than optics, which can highlight a person's charm.

Though the sun and its warmth keep our planet alive, it also gives off harmful UV radiation. UV radiation can damage your eyes—permanently. To keep your eyes in good health, it’s important to wear sunglasses with UV protection. Prescription sunglasses can block 100% of the sun’s UV rays, protecting your eyes from the damaging effects of UV ray damage, including macular degeneration, cataracts, and even cancer. That way, they have protection against the worst the sun has to offer.
