guide and tips for buying sunglasses
In this article we are going to present a small guide with the best tips for buying your sunglasses.
You already know that wearing quality sunglasses to protect your eyes is essential for their ocular health. At first it may not seem important, but sunglasses that are not approved or with low quality plastic lenses can cause serious damage to our vision in the medium and long term.|
That said, here is a guide with basic tips to acquire your sunglasses without making mistakes, especially when you buy glasses online.
Always buy approved sunglasses:
This has been talked about and warned on more than one occasion. Approved sunglasses are the only ones that can ensure that your anti-radiation UV filters are of quality. The difficulty is in verifying if the CE mark of the sunglasses is authentic or not. To avoid mistakes, always resort to trusted opticians or department stores.
You must wear your sunglasses all year:
To prevent the annoying dry eye, corneal damage, photokeratitis or pterygium, it is necessary that your eyes are protected from the Sun throughout the year, not only in summer.
A goggle for every use:
You must take into account the use that you are going to give your sunglasses. Sunglasses for mountaineering are not the same as others for water sports. Always keep this in mind before deciding on your sunglasses.
Solar filters in sunglasses:
Filters range from 0 to 4, with 4 being the maximum protection. The normal thing is to wear glasses with a minimum of 2 or 3 to obtain greater protection.
Each crystal has its function:
The color of the lens has nothing to do with the degree of protection of the glasses. Something very different is the color of the glass of the glasses, since the darker glass lenses protect better from sunlight than the lighter ones. Important note for people with light eyes. Polarized lenses can protect more from the sun than standard lenses, but they can cause problems when viewing the screen of our mobile phone or tablet, as well as being uncomfortable for some people.
These types of lenses block reflected light, letting only what is known as "useful light" pass through.
If you are fond of water sports or skiing, polarized lenses are ideal to protect your eyes from extra reflections caused by the reflection of the sun's rays in the water or snow. Even if you are a driver, they can be useful in protecting our eyes from the reflections produced by the sun on the asphalt.
Use yellow or orange lenses for night vision:
The crystals with these colors greatly improve the quality of our vision over long distances, which is why they are usually recommended for night driving.
Nearsighted best with brown glass:
According to some studies, myopic people are more comfortable with brown colored crystals. People affected by refractive surgery or cataracts will also feel better with this lens color.
