Take it easy, you should make out whether your daughter has gotten an eye infection. Symptoms of eye infection include increasing redness of the eye or eyelids, pain in the eye, eye discharge, watery eyes, dry eyes, light sensitivity, swollen eyes, swelling around the eyes, itching, blurred or decreased vision. And there are many different types of eye infections caused by different factors. Now that you suspect an eye infection your daughter is suffering, why not take her to the eye doctor for a thorough examination? Trying to diagnose your daughter's condition on your own can delay effective treatment and harm her sight in serious case, although most eye infections can resolve with minimal or no treatment. Foods rich of vitamin A, vitamin C and vitamin E such as livers, eggs, milk, carrots, spinaches, leek, sweet potatoes, cucumber, cabbages and dates are good for eyes. You can cook salmon, krill, cod and tuna for your daughter to supplement essential fish oil, which also benefits eyes much.
