Look after your eyes this summer

THERE is often so much emphasis placed on skin care during the summer months, that it’s easy to forget about the importance of caring for your eyes at this time of year.

“We are entering the holiday period and for many of us this means hours spent next to the pool, on the beach and generally outdoors. What we may not realise is that extended sun exposure can cause permanent damage to our eyes,” says Peter Jordan, principal officer for Fedhealth.

According to the Skin Cancer Foundation, although the eyelid is designed to protect the eye, its skin is exceedingly thin and contains many fragile tissues that may be injured by UV light. Inside the eye, the lens and the cornea, both transparent, filter UV rays, but by doing so for many years, can become damaged. This is especially true for the lens, which through years of UV absorption turns yellowish and cataractous.

UV exposure is directly linked to, for example, 10% of all cataract diagnoses, a progressive clouding and yellowing of the crystalline lens. Cataracts are the leading cause of blindness in South Africa. “Fortunately cataracts are treatable through surgery but could be prevented through better eye care,” says Jordan. Some eyelid cancers, intraocular melanoma, conjunctival cancers and benign growths of the conjunctiva can all be linked to sun exposure.

Excessive exposure to UV from the sun or tanning machines can literally burn the cornea, the eye’s clear refracting surface that admits light and images to the retina. This condition is known as Keratitis, or corneal sunburn. UV-protective lenses are therefore especially a must for anyone who uses a tanning machine. They are also essential for those who enjoy outdoor activities such as sailing and fishing as water reflects the sun’s rays.

“An important point to remember is that eye-damage from UV rays can occur throughout the year. Investing in a good pair of UV-protection sunglasses and a broad-rimmed hat is a good place to start,” says Jordan.

He offers these additional tips on eye-care: Check the UV protection level on your sunglasses. They should provide more than 95% UV protection. The lens tint is also important. The tint should block 80% of transmissible light but not more than 90% or you’ll strain to see through them.

• Don’t be fooled by cloudy days. UV rays can pass through clouds.
• Keep your eyes hydrated if they start to feel dry and irritated. Speak to your optometrist about what drops are best for your eyes.
• Never look directly at the sun – even during an eclipse.
• Protect your children from sun-related eye damage by ensuring they wear hats and sunglasses too.

“It’s important to regularly visit your optometrist for a thorough eye exam as virtually all UV-related eye conditions can be detected by your optometrist. It’s never too late to start caring for your eyes so make the effort today and enjoy the long-term benefits of healthy eyes,” concludes Jordan.
