SLIDE ON SOME SUNNIES - Wearing sunglasses can save your eyes

WITH summer well and truly upon us, Optometry Australia has warned us to not only slip, slop and slap, but to slide on some sunnies to protect our eyes from the sun's harsh rays.

Just like our skin, our eyes are susceptible to sunburn.

Optometry Australia resident optometrist Luke Arundel said eyes are more sensitive than skin to UV rays. Without protection they are at risk of photokeratitis, a painful eye condition that occurs when eyes are exposed to too much ultraviolet (UV) radiation. It's common, particularly when a person has been unprotected from reflected glare.

"Photokeratitis can occur in one or both eyes simultaneously," he said.

"Similar to sunburn, like that which occurs on your skin, it is not usually noticed until well after the damage has occurred.

"Symptoms include pain, redness, blurriness, tearing, swelling and sensitivity to light."

Mr Arundel warned that the risk to children's eyes from sun exposure is significantly greater than for adults.

"We believe that while many parents and schools will not let children go outside without sunscreen or protective sun clothing, they are not putting enough emphasis on sun damage to children's eyes.

"UV radiation from the sun can cause significant damage to a child's eyes and lead to serious eye conditions later in life, so we are urging those who care for children, to work with us to stamp out some of the problems caused by sun exposure.

"Wearing a hat simply doesn't offer enough protection.

"The simple solution is to always encourage children to wear sunglasses when outdoors.

"Adults can also become a role model in cutting down sun-related eye conditions by always wearing sunglasses outdoors, year round."

Mr Arundel said many conditions affect the eyes that are related to UV exposure, such as cataract, macular degeneration, pterygium (a fleshy growth over the front of the eye) and even eye cancers.

Optometry Australia encourages people to wear sunglasses all day and all year round.

"Maximal UV exposure for skin is 10 'til 2 but because our brow blocks a lot of direct UV rays entering the eyes in the middle of the day, maximal ocular exposure happens when the sun is lower on the horizon, which is why it's still important to wear sunnies in winter," he said.

And it is not only the direct sun on a fine, clear cloudless day that can cause damage. Up to 90 per cent of ultraviolet rays can reach the eye through clouds and light reflected from the ground and off sand, snow or water is also a significant factor.

Optometry Australia suggests the following tips for parents (or grandparents):

  • While you don't have to spend a fortune buying sunglasses for yourself or youngsters, always check the tag as sunglasses sold in Australia must state the level of UV protection
  • Go for sunglasses marked category 2, 3 or 4 to provide good UV protection
  • Novelty or toy sunglasses with coloured lenses in category 0 or 1 don't provide enough protection and should be avoided
  •  Polarized lenses are great for cutting reflected glare and are useful for the beach, fishing and driving
  • Sunglasses are also available for those who need prescription lenses and come in tinted, polarized or variable colour (photochromatic) options
  •  Close-fitting, wraparound styles and sunglasses with thicker arms help block glare entering the eyes from the side of the head
  • It's never too early for children to wear sunglasses so get them in the habit of doing so while they're young. Sunglasses with an elasticated band around the back can help to keep them in place. If older children are having trouble wearing sunglasses, the next best thing is a broad brimmed hat that provides some shade for the eyes - but note that hats stop only around half of UV rays from entering the eyes.
  •  For young babies, a cover over their pram will help protect skin and eyes from the sun's rays.
