Eyecare: Excessive exposure to UV light can lead to photokeratitis
Excessive exposure to the sun’s UV rays can lead to a sunburn-like condition called photokeratitis. This can be extremely painful and make your eyes red, swollen and watery. The symptoms of photokeratitis normally clear up quickly and cause no permanent damage to the eye, however, unprotected exposure to the sun over a long period of time greatly increases your risk of developing cataracts and other age-related conditions which can seriously impair vision later in life. Children are thought to be at the greatest risk from UV exposure because
the cornea, lens and fluids in their eyes are much clearer, allowing
more UV light to reach the retina.
NEVER let your child wear toy sunglasses. These offer little UV protection and can actually cause more damage because the tinted lenses dilate the pupil allowing even more UV light to enter the eye. Check that the lenses filter at LEAST 99% of the UVA & UVB light and look out for the CE or BS EN 1836:1997 marks when choosing sunglasses for your child as this ensures that they offer a safe level of UV protection. |
