Dry eye is when there is insufficient tear production or unstable tear film that can lead to irritation, burning, foreign body sensation, or pain of the eye; blurry vision or even reflex tearing. Not uncommon, patients of dry eye also experience soreness or tiredness of they eye, especially after prolonged reading or computer work.

Dry eye is very common. There are many factors that may contribute to the development of dry eye. Often time though, we do not know why a patient has dry eye. Regardless of the cause, the modifying factors or treatments are the same.
• Avoid over-the-counter or prescription medications that can contribute to dry eye
• Avoid drafts from heating or air conditioning vents
• Take frequent breaks during long period of computer use or reading
• Avoid wearing your contact lenses more than 8 hours

In severe, refractory cases, the opening to the tear duct is closed with a punctal plug or surgically to prevent draining of the tears.
