Wear properly and care for the condition
Breathability and corneal health: Modern contact lens materials in breathability and other aspects have been greatly improved, as long as the choice of qualified quality, good oxygen permeability products, wear time is reasonable, generally will not have a significant impact on the respiration of the cornea, cornea can maintain normal metabolic and physiological functions.
Tear circulation and wetting of the eye surface: Suitable contact lenses usually do not interfere with the normal tear circulation, and the eyes can be kept moist and clean through the secretion and flow of tears, reducing discomfort caused by dry problems.
In case of improper wear and care
Infection risk
Bacterial infection: If you do not pay attention to hand hygiene when wearing contact lenses, or improper cleaning and care of contact lenses, such as no regular cleaning, replacement of care solution, etc., it is easy to lead to bacteria, fungi and other microorganisms on the lens breeding, and then lead to eye infections, such as bacterial conjunctivitis, keratitis, etc., may appear red eyes, pain, increased secretions and other symptoms.
Viral infection: In some special cases, such as contact with patients with viral eye diseases, then wearing contact lenses may also increase the chance of viral infection, causing diseases such as viral conjunctivitis.
Corneal hypoxia
Long-term wear: If you wear contact lenses continuously for a long time, such as more than 8 hours or more, it will affect the oxygen supply to the cornea, resulting in corneal hypoxia. Long-term hypoxia may cause damage to corneal epithelial cells, corneal edema, neovascularization and other problems, affecting corneal transparency and normal function.
Poor material: If the contact lens material is poor in oxygen permeability, even if it is not worn for a long time, it may not be able to provide enough oxygen to the cornea, which will also cause corneal hypoxia related problems.
Dry eye problem
Increased tear evaporation: Contact lenses will directly contact the eye surface, changing the stability of the tear film, speeding up the evaporation of tears, resulting in dry eye symptoms such as dry eyes and foreign body sensation. Dry eye symptoms may be more pronounced, especially in an air-conditioned environment or when electronic devices are used for a long time.
Reduced tear secretion: Long-term wearing of contact lenses may also affect the function of the tear glands, reducing tear secretion and further aggravating dry eye problems.
Mechanical damage
Improper wearing and removal: In the process of wearing and removing contact lenses, if the operation is not skilled or too rough, it may scratch the cornea or conjunctiva, causing eye pain, photophobia and other symptoms, and in serious cases may lead to corneal epithelium shedding, increasing the risk of infection.
Lens quality problems: If the contact lens itself has quality problems, such as the edge is not smooth, damaged, etc., it may also cause mechanical damage to the eye surface during wearing.
In order to reduce the damage of wearing contact lenses to the eyes, it is necessary to strictly follow the correct wearing and care methods, choose the right contact lens products, and regularly visit the eye doctor for eye examinations.
