I get stringy clear/yellow eye mucus. blurs over my pupil when i blink & hurts, so i remove daily w/ a cotton swab. how to get rid of permanently?

Allergies or blepharitis: Allergies cause mucous & tearing. Over-the-counter allergy medicine & eyedrops help relieve it. Zaditor (ketotifen) is a good eyedrop. Blepharitis also causes this. It's a minor infection of the eyelids. Crusting & tearing is common. Warm compress with daily baby shampoo washing of the eyelids helps relieve this. Severe cases are placed on antibiotics by your doctor.
