Sunglasses are primarily used as a fashion statement and they enjoy worldwide appeal. Everyone wants to wear them in order to make themselves look more appealing and also to keep up with the trends. But aside from being aesthetically pleasing to the eye, they also have other benefits. They protect our eyes from harmful effects in many ways. Given below are 5 reasons as to why your eyes need sunglasses for protection.
1. Protection from UV Related Diseases:
The main medical benefit of the sunglasses eye ware is that they protect the eyes from harmful Ultraviolet rays coming from the sun. UV rays have been linked to numerous eye cancers and diseases. One such disease worthy of mention is Cataracts which essentially clouds the lens of the eye over time. Although it typically develops as people get older, studies have indicated that wearing sunglasses regularly can significantly decrease the chances of this disease actually developing.
In addition to Cataracts, sunglasses eye ware also provides protection from Pterygium, which is a raised wedge shaped growth of the conjunctiva tissue over the surface of the cornea. It can be caused by long term exposure to sunlight, mainly UV rays.
2. Reduction in Eyestrain and Headache:
The pupils control the amount of light entering the eye by means of contraction. In bright sunlight, the pupil cannot contract enough to reduce the light entering the eye thereby causes squinting. Excessive squinting causes muscle fatigue which eventually leads to headaches and eyestrain. Sunglasses keep the pupils in check and aid in regulating the amount of sunlight entering the eyes to ensure clear and comfortable vision.
3. Noticeable Reduction in Glare:
One of the obvious and noticeable benefits of sunglasses is the dramatic reduction in glare. A bright sun can cause intense glare which can affect the eye’s ability to see things clearly and also cause watery eyes and eye squinting. Sunglasses reduce the amount of glare the eye counters. Polarized sunglasses in particular, are very effective when it comes to reducing glare.
4. Protection from Dusty Particles:
Mild or gusty winds blowing in one’s face is a pleasant feeling but wind also carries dusty particles with it. These particles are known to cause many corneal abrasions. Sunglasses act as an effective barrier against such harmful particles and prevent them from getting into the eyes.
5. Adaptation to Indoor Light:
A key feature of sunglasses is the smooth transition they provide from day to night or when entering indoors. Spending several hours outdoors can directly impact the eyes ability to adjust to the indoor environment. It can also hamper its ability to see correctly at night. Sunglasses are an instrumental eye ware that can help in eradicating this problem and aid the eyes in adjusting accordingly.
To conclude, sunglasses simply do not have any drawbacks whatsoever. They are popular, excellent for the human eye and make a person look attractive. The human eye is a very sensitive organ and is also vulnerable to the harmful effects that surround us. Wearing sunglasses will effectively shield your eyes from these effects and keep it in good ocular health.
