When creating a custom pair, you have a variety of lens tints to choose from, as well as options like polarized or mirrored lenses, both of which reduce sun, UV rays and reflection glare — and yes, you want some anti-glare coating at a minimum, that’s a must. Gray, green and brown tints are the most popular. I tend to go with gray, but some sites also offer yellow, blue or rose options. (This is a good guide to lens colors.) Tint density is also important, with a higher density blocking out more sunlight. Nonfashion sunglasses’ tint density tends to range from 50% to 80%. You can also get gradient tints that offer more density in different parts of the lens.

Best prescription sunglasses
Several CNET editors have bought their glasses from Warby Parker, which has a good selection of sharp-looking eyeglass frames. While glasses start at only $95 with a single-vision prescription, chances are you’re going to pay a bit more — around $150 to $200 — based on the type of frame options you choose, your prescription and the type of eyeglass lenses. Sunglasses start at $175, and progressive lenses in both eyeglasses and sunglasses start at $295. Based on my and my co-workers’ experience, the finished products tend to be a step up from what more budget-oriented sites offer.
Notable site features: The company’s iPhone app — sorry, there’s no Android version yet — allows you to search the site by frame size and to try on various frames virtually (it works surprisingly well) and better yet, you can try up to five frames at home for five days for free. Once your five days are up, you place your box in the mail with the prepaid return label. Hopefully, you find at least one style that you like from among the five you picked for the home trial. There’s also a $15 online virtual vision test to renew outdated prescriptions. (Based on the test, you may not be eligible.)
Shipping times: According to Warby: “Single vision glasses take seven to 10 business days to reach you from the time we have all of your order information. Sunglasses and progressives take 10 to 12 business days to reach you.” (These estimates jibe with the experience of CNET editors who have used the service; my pair arrived in six business days.) You can pay more for expedited shipping.
