Usually, when buying sunglasses, many of us focus on the frame and the color of the shades. Another essential thing is to check if your sunglasses have UV protective coating. The UV coating is crucially important since it protects your eyes from the damaging UV radiation.

What is UV radiation?

The UV stands for ultraviolet, which is the invisible part of the spectrum of electromagnetic radiation with a wavelength from 100 nm to 400 nm. We divide it into three types: UVA, UVB, and UVC. Increased exposure to UV light can cause permanent eye damage, cataracts, or even corneal inflammation.

The main difference between each UV radiation is its range of and how it affects our skin.
UVA - UVA radiation has the longest wavelength and it reaches deep into skin layers, causing wrinkling and aging. It’s prevalent in all seasons - so you should protect your skin and eyes all year long.
UVB - UVB radiation has the highest impact on our health, excessive dose of UVB radiation is causing sunburns, redness, or even skin cancer.
UCV -  UVC radiation have the shortest wavelength, which means it does not pass through the atmospheric zone.

Symptoms of damage from UV exposure
• Blurry vision
• Eyesore
• Redness in the eye
• Light sensitivity
• Temporarily loss of vision

MYTH N. 1 - I don't need to wear sunglasses in cloudy weather or winter

Approximately 90 percent of UV rays penetrate through clouds. UV rays reflect from surfaces such as snow, roads, sand, water, and glass. Sunglasses are crucial eye protection in any weather conditions. Even 50 percent of UV radiation can penetrate to the eye even if you are standing in the shadow.

MYTH N.2 - Children don't have to wear sunglasses

Children usually spend more time outdoors than adults - many children’s activities are outdoor-based,  e.g. playtime, sports, or school. Children's eyes are much more vulnerable than adult eyes because they are not yet sufficiently developed. Teach your offspring to wear sunglasses every time they are outside and how to take care of them. Unfortunately, most of the sun damage happens before turning the age of 18. 

Children (especially younger than 2 years) should be protected as much as possible during the sunny days. Direct sunlight falling on a sensitive child's eye can lead to dry eye syndrome, or eyelids and corneas inflammation. Kids want to be like grown-ups - when they see you wearing sunglasses regularly, they are willing to follow your example.
