Q and A: Drink more water to protect eyes in summer

 During daytime, protect eyes and face from sunlight by using sunglasses that offer UVA and UVB protection, and a helmet with visor when riding two-wheelers. Similarly, factory workers in hot, dry, dusty environments should wear safety goggles. In the short term, they will protect against red, painful eyes and in the long term against early onset of cataract and pterygium.

 Products with chemical content such as chlorine, hair dyes and sprays, cleaning agents like bleach should be avoided. Cosmetic products like make-up brushes can harbour a lot of germs during summer.

 Drink plenty of water, as dehydration makes eyes feel tired and gritty, reducing tear production. Adequate sleep is required as tired eyes gets dry. Do not self-medicate or use drops advised by pharmacies, as they may give drops containing steroids and/or antibiotics for instant relief. Drops for ‘eye redness’ are not advisable. Instead, visit an eye doctor in case of red eyes, blurry vision, puffy eyes or discharge from eyes.
