With the temperature soaring higher and higher every day, it reduces our willpower to go through our everyday routine successfully. Sweat, rashes and lethargy are common hindrances during the months of summer that may stop us from achieving our goals.

The unbearable heat of the afternoon sun, in the peak of the summer season, is a known menace as it not only makes people exhausted beyond measure but is also responsible for heat-related health disorders like severe dehydration, heat cramps, low blood pressure and even fatal diseases like sunstrokes and skin cancer.

With summer showing us its true colours, it is time we gear up and not let it get the better of us. 

How does the sun affect your eyes?

Depending on the intensity and duration of the exposure to the sun, your eyes can suffer from several diseases. Below are some vision disorders the rays of the sun can increase the risk for:

• Cataract– Although known to affect older individuals, the ultraviolet rays of the sun can speed up the process of degeneration of the natural lens of the eyes and increase the chances of cataracts even in younger individuals.
• Skin cancer of the eyelids– The skin protecting our eyes is thinner and more sensitive compared to the rest of our skin. It is more prone to sun damage and even skin cancer.
• Photokeratitis– Too much exposure to the sun can damage the cornea, causing Keratitis.
• Macular degeneration– The harmful ultraviolet rays of the sun can penetrate the natural lens of the eyes, causing significant damage to the macula which can result in vision loss.
• Dry eyes– Your eyes can get excessively dry and itchy if exposed to the sun for prolonged periods without adequate protection. Lack of presence of the natural lubrication of the eyes can end up damaging them in the long run.
• Photosensitivity– people with photosensitivity may get headaches, pain in the eyes and discomfort when exposed to direct sunlight.  

Pterygium development on the conjunctiva, that abnormally covers the white portion of the eye, can be brought on by UV radiation, wind, and dust. Hence, wearing sunglasses may stave off radiation and protect the eyes.

Sunglasses: Are they just a fashion fad?

Sunglasses undoubtedly make us look trendy and can be paired with any kind of clothing. However, the main idea behind wearing sunglasses is to provide some form of protection to our eyes from the blinding light of the sun which normal spectacles are unable to provide. Sunglasses protect our eyes as well as the sensitive areas surrounding our eyes. 

One should consider the following points – Opting for good quality sunglasses that offer maximum ultraviolet ray coverage for both UV-A and UV-B is smarter than opting for a pair of sunglasses that just look the fanciest. 

• Bigger sunglasses offer wider coverage, so opt for oversized sunglasses to give yourself a hip look. 
• Wearing sunglasses regularly can reduce the risk of several vision disorders associated with ultraviolet rays from occurring. 
• Wear sun-protective eyewear even when you go swimming in daylight.

Researchers suggest one should wear sunglasses all year round. Sunglasses are believed to block UVA and UVB rays. It may minimise eye strain and glare. It may protect against wind, dust, and objects and aid eye conditions, including macular degeneration and cataracts.

Taking adequate measures to protect yourself from the sun is important during the season of summer to keep yourself fit and healthy. Sunglasses can do wonders in protecting your eyes from the harsh rays of the sun not just during summers but throughout the year. Keeping yourself hydrated, putting on sunscreen and limiting sun exposure are keys to staying healthy during the summer months.
