As soon as sunny days arrive, a burning question arises for all glasses wearers: how can you effectively protect your eyes from the sun without sacrificing visual comfort? Today, excellent options are available to you. But between the magic of photochromic lenses, the cleverness of the magnetic clip, and the incomparable style of true prescription sunglasses, it can be hard to decide! Follow our opticians' guide to find the perfectly adapted solution for your habits and budget.
1. Photochromic lenses (Transitions): All-in-one freedom
Variable tint lenses (often called Transitions, after the leading brand name) are true marvels of technology. They are clear indoors and darken automatically as soon as they are exposed to the sun's UV rays. The sunnier it is, the darker they become.
- The major advantage: You have absolutely nothing to do. You keep the same pair of glasses on your nose all day, whether you're moving from the office to a café terrace.
- What you need to know: Standard lenses react to UV rays. However, modern car windshields are treated against UV. As a result, your glasses will darken very little behind the wheel. (Note that there are specific ranges, like Transitions XTRActive, specially created to also darken inside a car). You also have to wait a few minutes for the lens to become completely clear again when you go back indoors.
2. The magnetic sun clip: Budget-friendly versatility
A frame with a magnetic sun clip is designed to accommodate an ultra-light sun overlay that snaps directly onto the front of your prescription glasses. With a single "click," your optical glasses turn into sunglasses.
- The major advantage: This is the gentlest solution for your wallet! You only pay for your prescription lenses once. Moreover, the supplied clips are very often equipped with polarized lenses, ideal for eliminating dazzling reflections while driving or near water.
- What you need to know: You must always remember to slip the small pouch containing the clip into your bag or pocket before going out.
3. Prescription sunglasses: Ultimate protection and style
This is the "high comfort" option: you choose a true sunglass frame (wider, more curved to cover the sides well), and our opticians fit it with tinted prescription sun lenses, perfectly adapted to your vision.
- The major advantage: Optimal coverage against UV rays and wind, combined with an uncompromising look (sports glasses, shields, oversized designer glasses).
- What you need to know: You need to plan the budget for a complete second pair (frame + tinted prescription lenses), which can represent a significant cost, especially for presbyopes requiring progressive lenses. Plus, you have to juggle two separate cases.

Our Opticians' Advice

Frequently asked questions from our customers
Do photochromic lenses work in the car? +
Standard photochromic lenses react to UV rays. Since windshields block the majority of UVs, the lens darkens very little. For driving, you should opt for specific treatments (like Transitions XTRActive) or choose a classic clip-on/sunglasses.
What is the most economical solution? +
The frame with a magnetic sun clip. You buy a single frame and only pay for one pair of high-end prescription lenses. The clip offers you sun protection without having to buy tinted prescription lenses.
Can I get progressive lenses with these three solutions? +
Absolutely! Our opticians accurately fit your progressive lenses whether you choose a photochromic treatment, a magnetic clip-on frame, or a dedicated sunglass frame.
