Dry eye is a complex disease that has many causes that often overlap and interact. For many people, a few simple lifestyle changes can resolve dry eye. For a long time, omega 3 supplements were thought to help alleviate dry eye. But new studies show that omega 3s are not very effective. Dry eye occurs when the eye does not produce enough tears or when the quality of the tears can’t keep the surface of the eye adequately lubricated. It frequently occurs with other health conditions. Environmental triggers, such as pollution or the weather, play a role. Sometimes it’s caused by medications, such as antihistamines, asthma medication or birth control pills. It can be made worse by computer or contact lens use. If your eyes remain red and irritated after trying these tips, see your ophthalmologist, a physician who specialize in medical and surgical eye care.
