Visine is a decongestant that relieves redness in the eyes brought about by minor irritations such as dust, smoke and swimming. This drug works by temporarily constricting blood vessels in the eyes, explains WebMD. Overusing this medication can result in increased redness after the drug effect subsides. The use of Visine should not exceed three or four consecutive days.
People should only use Visine as per a doctor’s instructions or the medicine label, states Drugs.com. Children under 6 and people who are allergic to any of the ingredients should not use Visine. Pregnant and breastfeeding women and people taking any other medicine should consult a doctor or pharmacist before using this medication. When a person experiences blurred vision following Visine application, she should not operate machinery, drive or undertake any task that could lead to danger until she is able to see clearly.
