What To Look For
Photochromatic glasses, also known as photochromic glasses, are prescription glasses that darken with exposure to UV rays, eliminating the need to buy an extra pair of prescription glasses. Your photochromatic glasses should first meet the needs of your prescription. Choose a particular style and lens type, polycarbonate, plastic or high index. High index are the thinnest and most expensive, available in both plastic and glass. Polycarbonate lenses are the lightest and most durable lenses at medium cost. Plastic lenses are the cheapest, but not as scratch-resistant.
Common Pitfalls
Most car windshields are equipped with UV protection, blocking rays and preventing your sunglasses from darkening. If you plan on wearing your photochromatics in the car, choose a lens that is designed for driving. Do not assume that your photochromatics completely protect your eyes from UV rays. While photochromatics react to UV rays, they do not necessarily block all of them.
Where To Buy
The best place to buy photochromatic sunglasses is your local optometrist's office. Not only can you try on several frame styles and lens shapes, you can get the professional advice of your optometrist. If you cannot shop for photochromatics in a store, go online to major retailers like Frames Direct and Just Eyewear.
Cost
The cost of the best photochromatic sunglasses ranges from $100 to $700 with frames. The cost of the transitions lenses range from $60 to $350 for a pair of glasses. If you have insurance, you may be entitled to a new hardware credit every year, which can discount the price of transitions. If you need a new prescription, consider the cost of an evaluative appointment with your optometrist to get a new prescription.
