My eyes are always red. I went to doctor. He wrote prescribe "artelac rebalance" eye drops. I almost finished second one. But still they are red.

Artelac Rebalance. Is a lubricating drop to treat dry eyes. This will help improve dry eye symptoms but may not help redness. This is especially true if you have chronic eye allergies or if your eyes are red because of chronic sunlight exposure. There are other treatments, but avoid using "get the red out" drops long term because they don't treat the underlying cause of your symptoms. Talk to your eye doctor.
