what are the dangers of wearing contact lenses

Many people are now abandoning traditional framed glasses for contact lenses for a variety of reasons. While it is true that contact lenses are more distinguishable and aesthetically pleasing, they can be harmful to the body if worn for long periods of time.

Causes corneal infections

Contact lenses are a thin plastic film that attaches directly to the cornea, and although it is a very thin layer, it acts as a barrier between the cornea and the air. If you wear contact lenses for a long time, it will directly affect the function of the tear film, which transmits oxygen to the cornea, so that the cornea can easily be in a state of oxygen deprivation for a long time. Corneal hypoxia can easily cause prolonged congestion and edema around the cornea, making the cornea fragile and prone to infection if contact lenses are not worn with care.

Paralysis of the eye

Wearing contact lenses for long periods of time can seriously harm the nerve endings in the eye. Because contact lenses are attached directly to the eyeball, we say that there is no room for sand in the eye. There are many nerve endings within the eye tissue that have a very distinct sense of the tiny foreign objects inside the eye. If you wear contact lenses for a long time, it is easy to cause nerve endings paralysis, the cornea of the eye perception is reduced, once the eye disease discomfort, you can not notice in time.

Decreased eye resistance

Wearing contact lenses for a long period of time can easily cause the resistance of the eyes to decline. Because contact lenses are close to the cornea, they can easily affect the normal metabolism of the cornea, which can easily reduce its ability to resist germs when it is in an abnormal metabolic state for a long time. In serious cases, it may also cause keratitis and corneal ulcers due to viruses.

Causes dry eye syndrome

Wearing contact lenses for a long time can cause eye fatigue, especially in the eyes, which can lead to many uncomfortable symptoms, such as increased eye stool, dry eyes, foreign body sensation in the eyes, etc. If these symptoms are not treated with care, they can easily lead to serious dry eye disease.

Corneal wear

Wearing contact lenses for long periods of time can cause corneal wear and tear, resulting in the loss of corneal epithelium. It is important to know that a person who wears contact lenses for long periods of time will have a corneal endothelial cell density that is much closer to that of an older person who cannot tolerate any eye surgery. Plus, contact lenses that are not concave or convex to the eye can easily wear down the cornea and cause corneal lesions.

Causes eye allergies

Wearing contact lenses for long periods of time can easily lead to eye allergies. Contact lenses can absorb proteins, lipids, collagen, etc. from tears and accumulate all these adsorbed substances on the surface of the lens, which can easily breed bacteria. When wearing contact lenses for a long time, bacteria can easily cause corneal edema and corneal neovascularization, leading to allergies, etc.

Excessive financial burden

Wearing contact lenses will inevitably cause corneal hypoxia, so you should try to wear them as little as possible, and if you must wear them, you should pay attention to choosing better quality contact lenses with better oxygen permeability. In order to avoid infection, it is best to choose the shorter use cycle, daily disposable is the best, but this can easily cause excessive economic pressure. It is best to choose contact lenses that are within your financial reach and have a short life cycle.
