BENEFITS OF SUNGLASSES FOR YOUR EYES: WHY IS IT ESSENTIAL TO ALWAYS WEAR THEM?

Among the benefits of sunglasses, the most significant is protection against ultraviolet radiation. There are different levels of filtration that guarantee, in their respective measures, the integrity of your eyes. However, to maintain healthy vision, it's essential to safeguard it at all times, something that's entirely possible with AWA Sunglasses. When you float in the water, you won't have to do without such an important accessory while swimming or practicing your favorite water sports.

What is ultraviolet radiation and what types of it exist?

Ultraviolet rays are included within the spectrum of electromagnetic radiation emitted by the sun. These are divided into three types based on their wavelength. From strongest to weakest, we find UVA rays, which pass almost completely through the atmosphere; UVB rays, which are absorbed around 90% by ozone; and UVC rays, which are completely blocked and therefore have minimal penetration into the Earth's surface.

Why it is essential to protect our eyes with sunglasses

Receiving small amounts of UVA and UVB radiation is essential for the production of vitamin D, which prevents conditions such as rickets, osteomalacia, and osteoporosis. However, excessive exposure is linked to serious skin consequences. In addition to burns, chronic dermatitis, and photodermatitis, it can accelerate the development of skin cancer.

On the other hand, there are potential negative effects on immunity, creating an ideal scenario for the emergence of infections. Even a person's general well-being can be disrupted, especially in terms of sleep-wake cycles, maintaining an optimal mood, and preventing emotional and affective disorders.

But the most immediate and obvious harm from ultraviolet radiation is its effect on our vision. If we don't protect our eyes at all times, we run the risk of developing conditions such as:

• Acute actinic keratitis and conjunctivitis
• Spheroidal degeneration of the cornea
• Corneal and conjunctival cancer
• Opacity of the lens or cataracts
• Pterygium
• Uveal melanoma
• Acute actinic retinopathy
• Macular degeneration

What levels of protection do lenses offer according to their filtration capacity?

To prevent these alterations, sunglasses come in different levels of protection. Categories 0, 1, and 2, which absorb up to 19%, 56%, and 81% respectively, are designed for low and medium light conditions. Therefore, while they may provide some aesthetic benefits, they are not recommended for ensuring eye health in summer, in places like the mountains and the beach, or when facing materials that reflect radiation, such as water or snow. In such cases, the best option is to use the two highest categories. Category 3 blocks between 82% and 92% of light, and Category 4 reaches 98%, making them unbeatable allies during the summer months.
