Why Sunglasses are Important for Eye Health
Ever wondered if wearing shades actually effective at protecting your eyes from sunlight damage?
According to Health Canada, “UV rays carry more energy than visible light rays, so the eye is at greater risk of damage from absorbing UV radiation than from absorbing other kinds of light.” These rays can cause or speed up the progress of several diseases that affect the eye or its supporting structures. Sensitivity to ultraviolet radiation varies from one person to the next.
Affects of UV light on your eyes
What does UV light do to your eyes?
Your eyes can become damaged when they absorb UV radiation (aka UV light). The process creates heat and a chemical reaction in the eye tissue. These reactions can cause permanent damage if the eye’s natural ability to heal itself is overwhelmed.
the Limits of Your UV Stress on Your Eyes
How can your eyes become overwhelmed by UV radiation?
If visible light is too bright or intense, or if you look directly at the sun your retina can quickly be damaged, possibly causing permanent vision impairment. There is some evidence that daily exposure to UV radiation in very bright sunlight over years may increase risk of developing cataracts.

UV Light in Winter Season
Are there risks to your eyes from sunlight in Alberta winter season?
In winter, UV radiation directly from sunlight isn’t as obvious, as it is often cloudy. But there is still UV light, if you see bright daylight all around you. The affect is amplified when the ground is snow or ice covered, as additional sunlight is reflected from the ground to your eyes. This situation coupled with cold/dry air and or wind is known as snow blindness. An uncomfortable but temporary condition.
Keep These Things in Mind
More advice on protecting your eyes from sunlight damage
Choose proper eyewear:
Eyeglasses should fit the shape of your face well, without distorting your vision, and dark enough to keep your eye comfortable, without being so dark that your vision is impaired.
Not all sunglasses offer the same protection: The amount of UV protection provided by any particular pair of sunglasses is not determined in any way by their price, colour, or by how visibly dark in colour the lenses are. (UV light is not in the visible light spectrum)
When purchasing sunglasses, check the label and ask an eyewear specialist to ensure that your next pair are in fact rated for filtering 100% of UVA and UVB rays.
Proper UV Protection is More Than a Pair of Sunglasses
When are sunglasses not enough protection?
Sunglasses are not capable of complete protection for your eyes from high intensity light sources such as welding flashes, tanning bed lights(recommend avoiding tanning beds for various health risks) long exposure to reflection from snow covered ground on a sunny day, and of course looking directly at the sun.
