Since your symptoms of thick discharge and itching have lasted for two months without improvement from allergy (Algic Plus) and lubricating (Refresh Tears) drops, you likely have a condition requiring different treatment. Thick discharge often indicates a bacterial infection or eyelid inflammation (blepharitis), rather than simple allergies. I strongly advise against trying alternative over-the-counter drops without a proper diagnosis. Please consult an ophthalmologist for an eye examination. You may need prescription antibiotic eye drops (like Moxifloxacin) or anti-inflammatory treatment. Meanwhile, practice good hand hygiene, avoid rubbing your eyes, and gently clean your eyelids with a warm, damp cloth.
