To choose the right sunglasses, it’s important to know the glare protection rating, since not all sunglasses are suitable for every purpose.
The absorption level, expressed as a percentage, is shown in parentheses:
Index 0 (0–20%): indoors and on overcast days
Index 1 (20–57%): on a cloudy day
Index 2 (57–82%): in fair weather
Index 3 (82–92%): bright sunlight, mountains, and beaches
Level 4 (92–97%): extreme brightness (not suitable for driving)
Photochromic lenses, which adjust to ambient light. They darken or lighten depending on the intensity of UV rays.
Polarized lenses are highly effective at reducing glare. They incorporate a film that filters out the horizontal component of light and allows only vertical rays—which are essential for vision—to pass through. We recommend these lenses for driving, water sports, and all board sports.
The glare protection index does not indicate UV protection.
However, sunglasses that offer poor UV protection can seriously harm your eye health.
In fact, the most important feature to look for in sunglasses is that they block 100% of UV rays.
But be careful: tinted lenses don’t necessarily mean they block UV rays !
In addition, all sunglasses sold at Optique Moitzheim comply with CE recommendations regarding UV protection.
In addition, sunglasses must be of good optical quality and free from defects such as bubbles, streaks or other impurities.
Everyone has their own preferences when it comes to sunglasses and lens colors, but each color has its own special characteristics:
Gray best reproduces natural colors
Brown, which is comfortable to wear, enhances contrasts
Green promotes a sense of well-being but slightly distorts colors
Yellow enhances contrast and can be useful for certain sports on gray days, but it increases glare as soon as the sun comes out
Pink and blue alter natural colors and are not very effective
Choosing the color of your lenses is a matter of personal taste and comfort.
However, it’s important to know that brown lenses enhance contrast and make it seem as though you can see better, especially for people with nearsightedness.
On the other hand, gray or green lenses—which have a more soothing color—are better suited for people with farsightedness.
