What are the dangers of wearing beautiful pupils to your eyes?

Eye contact lenses can cause dry eyes, conjunctivitis, keratitis, etc. If you wear them for a long time, tears will not cover the eye surface evenly. The epithelium on the eye surface will not get moist and nutritious tears for a long time. It will show dryness, damage and keratosis. After a long time, it will show dryness and discomfort. Wearing them often can cause protein and lipid to precipitate on the lens surface. If you wear them improperly, it will easily cause allergic conjunctivitis. Corneal epithelial damage can result from keratitis. If keratitis is not treated promptly and effectively, it can further develop into corneal ulcer, which will produce corneal scar after healing and thus affect vision.
