Eye drops are also helpful in preventing dry eye. Research has shown that vitamin A and cyclosporine drops can lead to great improvement in the symptoms of dry eye. These kinds of drops were found to be more effective than preservative-free artificial tear eye drops. While dry eye itself isn’t a harmful condition, it can lead to serious conditions that can harm your eyes, including eye infections and eyes damage. If you are exposed to conditions that can cause dry eyes, you can prevent the condition from occurring by gently washing your eyelids with a cloth and warm water. The best way to avoid allergic conjunctivitis is to avoid the substances that trigger your symptoms. But researchers have also found eye drops to be helpful in preventing allergic conjunctivitis in those who are prone to allergic reactions. The antihistamines emedastine and levocabastine are helpful in preventing the condition. Use these after you have been exposed to a trigger, such as a day with high air pollen levels.
