Question: how many times a day can i use optrex refreshing eye drops?
Answer: Apply 1 or 2 drops into your lower eyelid. Or, if you prefer, close your eye and apply 1 or 2 drops to the inner corner, then open and blink to spread the drops. Use Optrex Refreshing Eye Drops as often as you like to revive your eyes. The drops can be used every day.
