If you have read previous articles (here are 1st and 2nd parts), you've learned it is really important to remember about sunglasses when you are a fan of winter sports. Here is the third part of the guide: tint, color, and technology of lenses. Now you know you need to feel comfortable with your frames, check the UV protection, that glasses should guarantee, and choose the proper durability of material with which lenses are made of.
You need to admit that it is not only about the tint or mirrored effect that makes you look more handsome in your new sunglasses. If you have ever tried skiing or snowboarding, you know that during the day, light conditions may change. Also, if you are above the tree line on the slope, there can be much more light than at the foot of the mountain. The day might be sunny or it might be cloudy. That is why many tints and colors of lenses were introduced.
Let us shortly stress here different colors and their purpose:
Gray/Green - their color is neutral and was created to cut down on the intensity of light without changing colors. It just provides crisper contrast. These lenses are good for activities where color can be important.
Brown - they enhance the quality of light and increase contrast and depth perception. However, they can cause color distortion.
Yellow/Gold/Amber - they provide excellent contrast and depth perception. You have less protection from brightness, but that might be exactly what you need.
Rose - they block the hazy blue colors and are a good choice for many outside activities. They can be worn even for longer periods, as they cause very little eyestrain.
Blue/Purple - those were created for cosmetic wear, they don’t really have any functional value.
Mirrored or Flash Coating - they have a reflective film applied to the outside surfaces of some lenses. It is highly desirable when a big cut down on the bright light is needed. They reduce glare by reflecting much of the light. That is why mirrored coatings make objects appear darker than they are.
Now we can move to the lens technology. In stock we have:
Polarized Lenses - they block vertical light and protect your eyes from the light reflected by flat surfaces, like snow or water.
Photochromic - they automatically adjust to changing light intensities to protect you in a wider range of sunlight conditions.
Gradient Lenses - the top of the lens is darkest so they shield your eyes from sunlight and at the same time allow more light through the bottom half of the lens. That makes them perfect for driving.
Double Gradient - in this case, the top and bottom are the darkest and the middle has a lighter tint. These can be good for water or winter sports since they allow the light through the middle part, but at the same time, they shield your eyes from sunlight and the light reflected by the flat surface (ex. snow, sand or water).
Having this knowledge you can mix lens tints with the technology that they offer to get your perfect sunglasses! Keep in mind also all tips about frame size and materials, lens materials and UV protection issues. Thanks to that, your new sunglasses will be a buy for years to come.
