You should not rub your eyes with your hands too often, as they can carry bacteria or viruses that can infect the eyelid glands when you rub them, causing inflammation and promoting the formation of bumps. If you feel a foreign body in your eyes and want to rub them, you can do eye exercises to relax your eyes. You can look into the distance or take a break from reading books or electronics at intervals. If you have dry eyes, you can use artificial tear drops as appropriate with your doctor’s advice.
