How sunglasses can protect your vision?
Sunglasses are just more than fashion accessories. They protect eyes from the harmful ultraviolet (UV) rays of the sun. Choosing the right glass is essential for healthy eyes. UV rays increase risks of several eye diseases such as age-related macular degeneration and cataract.
Blocking of UV rays
Sunglasses block the harmful UV radiation and reduce the risk of eye diseases manifold. Not only this, they also prevent dust and other airborne particles from entering the eyes. There is a common perception among people that contact lenses provide complete UV protection. However, this is not true. Contact lenses with UV protection just protect the interior of the eyes but not the eyelids.
Eyelids are extremely thin and highly vulnerable to skin cancer. Sunglasses shield the fragile tissues around the eye and prevent the formation of wrinkles and thickening of the skin caused by exposure to UV rays.

The bigger, the better
The bigger the glass, the better it is. Wraparound sunglasses offer the best protection as they block light that hits eyes from the sides. Glasses with large lenses cover a wider area of the skin, thereby providing robust protection.

Purchase glasses with good quality lenses
Inexpensive sunglasses do not have polished lens. This affects the optical quality. Hence, it is advisable to check lenses' quality before using. It is recommended not to buy very cheap sunglasses.
To prevent eye diseases and vision loss, it is important to wear sunglasses when you are outside, particularly during peak hours (10am to 3pm). Rays are strongest at this point and going out naked eye can be harmful.
It is essential to note that sight can get affected at any season and not just in summer when sunrays are extremely strong. Doctors recommend wearing them even on cloudy days as UV rays can penetrate thin clouds and cause damage.
