Insight Into Eyesight: Drugs That Affect Your Eyes
Anti-histamines (Benadryl, Dimetane, others) causes an increase in pressure in the eyes and should be avoided by people with glaucoma.
Diuretics such as Chlorothiazide (Diuril) and Furosemide (Lasix) can cause dryness and blurred vision.
Plaquenil used in arthritis, lupus and malaria can reduce your ability to see the colour red and can cause a distortion of the central vision. Lines that are straight may look wavy, making reading difficult.
