Sunglasses – How to Choose the Best

There is such a great selection of styles and different price categories of sunglasses that it is sometimes difficult to decide what the best choice for us is. It is such a challenge to find the appropriate glasses that will make you feel beautiful and elegant and at the same time will be functional.

The most important thing when choosing sunglasses is to protect your eyes from the ultraviolet radiation. That’s why we recommend sunglasses that block 99-100% of UVA and UVB radiation.

The materials used for the lenses of the sunglasses are different – some are light, others are more durable. The most frequently used materials are: polycarbonate – it is durable and lightweight material; CR-39 – also a light material, commonly used in the manufacture of spectacles; glass-durable, but much heavier than the previous two.

Coverage of sunglass lenses:

The UV filter is a defense, but there are many others which may be added as extras.

Colors of sunglasses. The colors are applied to sunglasses to help in the absorption of the light passing through the glass. The color you select is a matter of personal choice, but each color has certain qualities:

 

  • Grey – it reduces the brightness of the light without affecting the perception of the surrounding colors.
  • Brown – reduces unwanted glare, including those of the blue spectrum of the sunlight that can cause blurring. Brown lenses change the perception of the surrounding colors.
  • Yellow – reduces the blur of the blue light better than brown glass, but they change the surrounding colors more.
  • Green – it reduces glare and filters out unwanted parts of the blue light. They give good contrast of the image.

 

Polarized lenses. They help in reducing unwanted glare when the sunlight is reflected in water or other smooth and mirror surfaces.

Protection against scratches – this is another coverage that is applied on the glass to make it resistant against scratches.

There are many types of sunglasses, like the mirror glasses, for example. On their outside, they look like mirrors because they are covered with special material. They are effective but unfortunately their surface is scratched very easily. Photochromic glasses are also interesting. They darken when exposed to UV rays – depending on the strength of the light, their color intensity changes. They are suitable for walking, working, driving and they give you maximum protection.

Sunglasses fashion changes every year just like the fashion with any other fashion accessories, but the selection is so large that there is no risk for the sunglasses that you bought to become outdated. The sunglasses of designer companies definitely cost a lot but if you seek more, you can find good sunglasses at a reasonable price. Just check if the sunglasses have the protection you need and everything will be alright. When you buy sunglasses, ask the salesperson to let you exit the store and try them out – thus you will get the most accurate idea how they will protect you from the sun.
