“Prolonged exposure to UV rays, emitted by the sun, can lead to severe damage and even vision loss.” This is according to prominent eye surgeon Ronnie Bhola. In an interview with Newsday, Bhola emphasised the importance of protecting our eyes from harmful UV rays.

Bhola, with years of experience in ophthalmology, highlights the potential eye damage caused by UV radiation. He warns, “UV rays can have negative effects on the eyes, leading to conditions like corneal damage, cataracts, and macular degeneration. It is highly recommended that everyone to take preventive measures to safeguard their vision.”

The effects of UV radiation on the eyes are well-documented, and various factors can increase a person’s vulnerability to these harmful rays.

Physical location matters

Bhola explained that UV rays are more intense in certain locations, such as beaches, higher altitudes, and countries closer to the equator. He advises people in these regions to be particularly cautious and consider wearing UV-blocking sunglasses and hats when outdoors.

Age and susceptibility

Certain age groups are more susceptible to UV radiation. “Children, in particular, receive three times as much sun exposure as adults. Their eyes are less equipped to filter out UV rays, making them more vulnerable,” warns Bhola. He adds that older individuals are also at higher risk of visual diseases due to prolonged UV exposure.

Eye colour matters

Surprisingly, eye colour plays a role in the level of UV protection. Bhola pointed out that "Lighter coloured eyes, especially blue eyes, filter out less UV radiation compared to brown eyes. Individuals with lighter eyes should take extra precautions when spending time outdoors.”

To safeguard eye health during UV Safety Month and beyond, Bhola emphasised the importance of adopting preventive measures recommended by the Eye Health and Safety Organisation to prevent blindness. "Wearing brimmed hats and UV-blocking sunglasses is the best protection against UV rays. It is essential to choose sunglasses that filter out 99-100 per cent of UV radiation.”

As families gear up for increased outdoor activities during July and August, Bhola urges the public to minimise sun exposure and prioritise eye protection. "By taking simple precautions, such as wearing proper sunglasses and hats, we can significantly reduce the potential harm caused by UV rays and preserve our precious eyesight,” he concluded.
