If you wear prescription eyeglasses, you can have special prescription sunglasses made with your own prescription in the lens. Most eye doctors will offer sunglasses along with regular eyeglasses. Prescription sunglasses offer more protection than photochromic lenses that change in bright or dark light. They are usually not more expensive than regular sunglasses, so there is really no reason not to have your prescription in sunglasses as well as eyeglasses.
Many frame lines offer both ophthalmic and plano sunwear pieces in their collections. Usually the ophthalmic offerings make great sunwear options and can be easily glazed with plano or prescription sun lenses. The sunwear choices can also be Rxed with sun lenses. The popularity of three-piece rimless mountings has inspired high-end sunwear designers and vendors to venture into prescription sunwear.
Don’t think of prescription sunwear as just a darkly tinted version of your clear prescription glasses; think of it as eyeglasses specially designed for your active lifestyle. With this definition, colored or multi-colored mirror coatings, anti-reflective coating, ultraviolet protection, polarized lenses, impact resistance, frame durability, and a host of other options become a spectrum of unique features to add to your prescription sunwear.
