Tips and Tricks
This type of lens is treated to reduce the amount of sunlight it allows through, but also the bright reflections that bounce off reflective surfaces like water, snow, or vehicles. Additionally, it improves colour contrasts and colour perception.
These lenses improve the quality of light filtration while simultaneously reducing the amount of light that reaches the eye.
The colour of your lenses affects the amount of visible light that reaches your eyes as well as how you perceive colour and contrasts, but it does not increase the protection against UV rays.
Darker shades are better suited for everyday use and the majority of outdoor activities. Their main purpose is to cut down on the sun's glare and reduce ocular fatigue in moderately bright to bright conditions.
Light colours are better suited for moderate to low sunlight. They are often used for winter sports as they provide excellent depth perception, improve colour contrasts and object visibility, as well as make the wearer's surroundings brighter.
ULTRAVIOLET (UV) RADIATION IS PRESENT IN THE SUN'S EVERYDAY RAYS. SINCE IT CAN TRAVEL THROUGH THE OZONE LAYER AND CLOUDS, IT'S IMPORTANT TO PROTECT YOUR EYES FROM ITS ADVERSE EFFECTS. WHEN BUYING NEW SUNGLASSES, MAKE SURE TO READ THE INFORMATION PROVIDED ABOUT THEIR UV PROTECTION.
UV protection index
This European scale indicates the filtering power of lenses. A number from 0 to 4 is written on the frames in order to convey this information:
0: Ultra light protection.
1: Adequate protection in winter or on grey days and days with little sun.
2: Adequate protection in average sunshine.
3: Effective protection in intense sunshine. Completely blocks UV rays.
4: Recommended protection in cases of extreme light. Prohibited while driving a car.
Certain sunglasses, even if they are low priced, will mention that they have 100% UV protection on their packaging. This way, your eyes will always be guaranteed to be protected from the sun's harmful rays.
Did you know?
When picking out your sunglasses, always make sure...
• The frames don't cover your eyebrows. The top of the sunglasses should stop just below them and follow their natural curve.
• The frames are proportional to the width of your face. Your glasses should not be wider or extend beyond the sides of your face.
