What is the best way to take care of my eyes?
Eyes need constant care for their proper functioning. Many eye diseases are preventable. Maintaining healthy lifestyle which includes regular exercise and eating a balanced diet with lots of green leafy vegetables and fruits containing vitamins, minerals and antioxidants can prevent degenerative diseases such as Glaucoma and age-related macular degeneration.
Preventing eye injuries is very important as they are one of the most common causes of visual loss. Wearing appropriate safety glasses during work and play can prevent these injuries. Children should be advised not to play with sharp objects.
Go for regular eye check-ups to detect asymptomatic diseases such as Glaucoma and Diabetic retinopathy so that timely intervention can prevent visual loss.
