Sunglasses are definitely a fashion favorite and a great tool for styling in the shinny summer. But how do we choose the right sunglasses? Do we really need them? How important is the color of the lenses? What about the size of the lenses and eyewear frame? There’s actually a lot to learn about this.
Choosing Lenses
How to pick good lenses? Sunglasses are categorized into light-absorbing, polarized, coated, and photochromic types. The best lenses are polished using optical procedures, just like the optical frame prescribed by doctors. Plastic lenses, similar to Rx ones, vary greatly in quality. Generally, plastic lenses are lighter, shatterproof, and cheaper; however, they are prone to scratches, so special care must be taken when touching or cleaning them.
There are several simple ways to test the lenses: Observe them under light. The lenses should be completely clear, with no cross scratches, streaks, circles, bubbles, or stains at all. Move the lenses up, down, left, and right to look at objects with distinct lines, such as window frames or door frames. If these objects appear wobbly or distorted, the lenses have distortions and are not usable. To check if the lens color is uniform, pay attention to whether the two lenses have the same color and if their gradually lightening parts are in the same positions.
Lens Colors
The price of sunglasses doesn’t entirely reflect their optical quality. Because the most expensive ones may just have novel designs, and what you’re paying for could be the fashionable eyewear frame rather than the optical quality of the lenses.
What color is the best? Generally, natural pure gray and “smoke” colors are the best. Lenses of these colors are the hardest to manufacture, so inferior sunglasses won’t use them. Next is green. Blue and red lenses are only used in certain industrial applications. There are also special yellow lenses. Therefore, the choice of lens color depends on the purpose. How dark should the color be? The darkest colors are suitable for use in strong light. It’s very dangerous to use them when driving on roads with fluctuating light conditions. Many people find the lenses of the sunglasses they buy suitable in brightly lit stores, but they turn out to be too light when used at the beach or in the countryside. The best way is to take the sunglasses outside and look at the sun. It’s advisable that only 20% to 30% of the light can pass through in strong sunlight.
