Choosing a lens tint isn't only a question of aesthetics. The colour and the level of darkening influence your visual comfort, your perception of contrast and even your everyday use (driving, screen, outdoors). This guide helps you select the right tint quickly, with clear, practical advice.
Tint levels: categories 0, 1, 2, 3 and even 4
The tint level determines the amount of light filtered. The higher the category, the greater the sun protection.
- Category 1: Absorbs up to 57% of light. Ideal for moderate indoor/outdoor use or slight light sensitivity.
- Category 2: Absorbs up to 82% of light. An intermediate category. A good compromise for everyday use and city activities.
- Category 3: Absorbs up to 92% of light. A dark tint. Recommended for outdoors and the beach.
- Category 4: Absorbs up to 97% of light. A very dark tint. Recommended in the mountains, prohibited for driving.

Classic colours: grey, green, brown
The standard colours are the most versatile and the most natural.
- Grey: faithful to colours, reduces glare without altering contrast. Ideal for driving.
- Green: preserves the rendering of colours, reduces visual fatigue. Comfortable outdoors.
- Brown: enhances contrast and depth. Much appreciated for outdoor activities.
✅ It's the "no-risk" choice for everyday use.
On-trend colours: amber, pink, purple, blue
These tints are more expressive and offer a strong look while keeping genuine visual comfort.
- Amber: warm, increases contrast.
- Pink: soft, bright and attractive.
- Purple: original, on-trend, accentuates nuances.
- Blue: fresh, modern, very popular in summer.
- Yellow: ideal for night driving.
👉 Perfect if you're looking for a fashion touch while keeping effective protection.
Graduated tints: elegance and comfort
A graduated tint is darker at the top and lighter at the bottom. It allows you to:
- Be protected from direct sun when looking straight ahead
- Keep clearer vision when looking downwards
- Maintain a chic, timeless style
✅ Ideal for city use, on a terrace or for light driving.
Photochromic: a lens that adapts to the light
Photochromic lenses darken automatically in the sun (with UV) and lighten indoors.
Benefits:
- A single pair for indoors and outdoors
- Permanent visual comfort
- Constant UV protection
⚠️ Note: in a car, the lens darkens less because the windscreen filters out UV.
Health insurance & cover: what to remember
- Photochromic lenses: cover by your mutuelle (top-up health insurance) is possible.
- Tinted lenses (other than photochromic): cover by your mutuelle is not possible (other than in specific cases).
