Bideford Specsavers store manager Jerry Shrubb gives you the lowdown on not letting the sun ruin your fun.
With North Devon enjoying a spate of sunshine, Specsavers in Bideford is reminding people to safeguard their sight.
Store manager Jerry Shrubb is warning that not all sunglasses offer adequate protection – whether at home or abroad.
He said: “Rays are heightened by glare, which occurs when light is intensified as it reflects off the bright shiny surface.
“A sandy beach or calm sea will have the same effect.
“So if your sunglasses do not provide adequate protection, your eyes will be exposed to more UV than usual and will suffer more damage.
“Excessive exposure can lead to optical health problems.”
Sunlight can also cause ageing to the skin around the eyes.
Jerry added: “The natural reaction to bright sunlight is for us to screw up our eyes, straining the surrounding facial muscles.
“This causes temporary crow's feet, which become permanent once the skin's elastin fibres become damaged by exposure to UV rays.”
So how do you stay safe? Here are Jerry's tips to protect your eyes in the sun:
1. Always use effective sun protection both for prescription and non-prescription glasses.
2. Ensure your lenses bear the CE kite mark and are UV400 effective. Specsavers stores can run a free UV check.
3. Wear your sunglasses even on days with cloud and sun, as UV rays penetrate cloud.
4. Try to avoid the sun between 10am and 2pm, when UV rays are most intense.
5. Wear big lenses for even more protection.
6. Invest in photochromic lenses that instantly adapt to light changes, darkening in bright light.
7. Wear sunglasses over your contact lenses as their UV protection does not cover the whole of your eye.
8. Ensure that your sunglasses fit properly.
9. If you are going on holiday and have prescription sunglasses, take your optician's phone number with you. If your sunglasses break, your optician can send your prescription to an optician near you so you can get new ones abroad.
