So what are the hazards of not removing contact lenses? Let's take a look at it together. Generally speaking, it is reasonable to wear contact lenses within 8 to 10 hours a day. If you wear them for a long time, it will be more harmful. Because contact lenses are covered on the cornea, and the oxygen absorption of the cornea is obtained through the air, if you wear it for a long time without taking it off, the cornea is prone to hypoxia. Wearing contact lenses is very harmful to the cornea. Corneal ulcers are not suitable for wearing contact lenses in the future. Bacteria can grow easily if you don't remove your contact lenses. We all know that contact lenses need to be cleaned and cared for, and it is important to keep them clean and hygienic. If the contact lens is not taken off, more protein and dust are easily deposited on the surface of the lens. These substances can cause the growth of bacteria, and the eyes are prone to dryness and redness. Bacteria invade the eye, causing inflammation, causing complications such as keratitis, follicular hyperplasia, dry eye syndrome, and damaging the health of the eye. If the contact lenses are not removed for a long time, the contact lenses will stick to the eyes, causing serious damage to the cornea, and some cells are destroyed and difficult to proliferate. In some serious patients, it is very difficult to remove the lens because the lens and the cornea are stuck together, and the damage to the eyeball is also great. In severe cases, it can cause blindness. Not taking off contact lenses will also reduce the immunity of the eyes and reduce the perception ability. When the eyes feel uncomfortable, it is also the time when the eyes are more damaged. And because the lens is covered on the cornea for a long time, the metabolism of the eye cannot be carried out normally, which affects the health of the eye. Especially when the seasons change, the eyes are more prone to infection, and some even suffer serious damage such as corneal ulcers and corneal perforations. Failure to remove contact lenses can cause vision loss. If the contact lenses are not removed for a long time, the corneal endothelial cells may undergo characteristic morphological changes, but many people do not feel it. For a long time, the harm of contact lenses to vision is also invisibly deepened, such as rainbow vision, photophobia, tearing, Vision loss will also appear gradually.
