Sunglasses have traditionally been perceived as a fashion accessory, yet their function goes much deeper. They play a significant part in shielding the eyes from damaging ultraviolet (UV) radiation, which can result in severe eye diseases like cataracts, macular degeneration and eyelid cancer. Quality sunglasses can block 99% to 100% of UVA and UVB radiation, serving as a barrier against solar radiation.
Sunglasses also eliminate glare, particularly from surfaces such as water, snow, and roads, enhancing vision clarity and comfort while performing activities outdoors. For this reason, they are vital not only for fashion, but also for the health and protection of eyes. Continue reading to learn how sunglasses protect your eyes and how to choose the appropriate sunglasses.
How to Choose The Right Sunglasses?
Check for 100% UV Protection
Always opt for 100% UVA and UVB protected sunglasses. This is the key point to shield your eyes from toxic solar radiation.
Think About Lens Quality and Material
Use scratch-resistant and optically correct lenses. Good material such as polycarbonate or glass ensures increased durability and better clarity.
Think About Polarised Lenses
If you are outdoors a great deal, particularly near water or when driving, polarised lenses can dramatically cut glare and enhance visual comfort and safety.
Check for Certification Labels
Make sure to look for certification labels such as ANSI (American National Standards Institute) or CE (European Conformity) marks which ensure that the sunglasses are up to safety and quality standards.
Select a Frame That Is Comfortable
The sunglasses must be comfortable enough to rest on your nose and ears. Ill-fitting sunglasses tend to fall, be uncomfortable and provide less protection against sunlight entering from the sides.
How Sunglasses Help Protect Your Eyes?
Block Harmful UV Rays
Quality sunglasses provide 100% protection against UVA and UVB. Ultraviolet light exposure over time can cause cataracts, macular degeneration and even eye cancers. Sunglasses prevent these severe eye diseases by serving as a barrier.
Prevent Photokeratitis (Sunburn of the Eye)
Just as your skin, your eyes can be sunburned also, a condition referred to as photokeratitis. Symptoms are pain, redness and transient vision loss. Sunglasses protect your corneas from powerful sunlight, particularly when in the vicinity of reflective surfaces such as snow or water.
Prevents Eyes from Wind, Debris and Dust
Besides sunlight, sunglasses act as a physical barrier against environmental irritants like dust, sand, pollen and wind. This helps prevent dry eyes, infections and corneal scratches.
