What information can you give me about vasocon eye drops use, risk?

Use something else: Vasocon is a vasocontrictor which gives you temporary relief but in the long run can irritate your eyes even more. It shrinks your blood vessels on the surface of your eye making them look white. But when you stop, your vessels dilate again. Eventually, you have to keep using them and this leads to chronic irritation. Use regular artificial tears instead.
