necessity. Sunglasses are of use throughout the year and not only on a bright summer day. Sunglasses are multi-purpose objects, and not just stylish accessories with fashionable outfits.
So first find out why sunglasses are so necessary?
Uses of sunglasses
The most obvious use of sunglasses is that it protects the eyes from dust and wind.
Whether you’re just sitting at the terrace and enjoying the view or going out to cycle, it is necessary to make sure you wear sunglasses to prevent dust particles from entering your eyes. You might have experienced some redness or irritation in your eyes at times after a few rounds of cycling. This is because you were not wearing sunglasses and harmful bacteria or dust has entered your eyes. Sunglasses help to keep your eyes moist and comfortable. For this purpose close-fitting or wrap style frames are better, as they prove to be an effective barrier to dust and debris.
Sunglasses help your eyes fight the harmful ultraviolet rays of the sun. Direct rays of the sun can really affect your eyes. These rays are harmful and can even affect your vision and eyesight severely, if eyes are exposed to these rays for a very long period of time at a stretch. Sun rays can also cause premature ageing, darkening, and wrinkles on the delicate skin around the eyes. It is very necessary to wear good quality sunglasses to prevent such damage.
Regular use of sunglasses can also enhance vision over time. Sunglasses lenses are always tinted in order to adjust overall brightness and TD (Terrain Definition). However the choice of tint of colour determines how much visible light enters your eyes, and how well you see different colours and contrasts. You should always choose the tint of colour that best suits your sport or activity because this will help adjust your acuity to that environment. From the eye care viewpoint, it is suggested to wear grey, brown or green sunglasses.
Cool sunglasses also help reduce headaches and eyestrain. A lot of people have headache issues when they step out in bright sunlight this is because the pupils can’t control the amount of light entering the eyes through the retina, which exposes the eyes to harmful ultraviolet rays leading to extra exposure leading to headaches.
It is hence very necessary to wear good quality Sunglasses on sale online because not only they protect your eyes from excessive exposure to harmful ultraviolet rays but also help retain the moisture in the eyes.
