Beyond making us feel more attractive and giving a personal and original touch to our look, sunglasses have important benefits for visual health
Sunglasses are already a basic accessory for many people throughout the year. But in summer this accessory becomes even more necessary. Since beyond making us feel more attractive and giving a personal and original touch to our look, sunglasses have important benefits for visual health that deserve to be known and taken into account. Do you know them?
The benefits of wearing sunglasses
Sunglasses have a much more important function for our health than giving us personality. For example, in summer they are even more essential because the sun’s rays fall perpendicularly on the earth and are even more annoying than the rest of the year, and therefore also more dangerous.
However, do not forget that summer is leaving, but UV radiation is not. So if we continue to wear sunglasses throughout the year, all the better.
How does the sun damage the eyesight
The sun’s rays are loaded with ultraviolet radiation (UVR), which causes damage to the skin and eyes. We differentiate two types of radiation: UVA and UVB.
UVA radiation penetrates the different tissues of the body, causing wrinkles, sagging and aging of the skin. While UVB rays are even more harmful and cause damage to the upper layers of the skin, such as burns or the development of cancer.
Some of the problems that the sun’s rays generate in vision are the following:
- Iris damage
- Burn of the cornea and / or eyelids
- Development of cataracts
- Muscle degeneration
The sun is also associated with patients with Pterygium, a disease that manifests itself as a spot that extends from the eyeball to the cornea. As with cataracts, this one is also operable.
On the other hand, the bright light from the sun can also cause eyestrain, since when there is a lot of light, the eyes are exposed to overload by keeping squinted. What usually happens when you are driving or reading in bright sunlight.
Prolonged exposure to the sun can cause headaches, dry, irritated eyes, and trouble concentrating.
Sunglasses, even more necessary in people with light eyes
It is true that people with light eyes suffer more from sun exposure. Generally this is because these people reject more light and have less protection, resulting in the most harmful rays. The same is true of skin type and chances of getting a burn. Dark coloured eyes such as brown or black filter rays better than green or blue ones.
What colour to choose sunglasses lenses?
According to experts, the colour of the glasses in the end depends more on the tastes of each person. Since practically all filter the same, as long as it is quality glasses like Ray ban sunglasses. And also, did you know that there are UV-blocking contact lenses? You can check it out at Contact Lenses Plus.
The best option is to be advised by the optician, since they know the qualities of each lens shade. For example, browns enhance contrasts, greens give a natural luminosity, and polarised lenses avoid reflections on the road or on the sea that can damage and dazzle.
