Abstract: do not wear contact lenses. Menstrual women and pregnant women had better not wear contact lenses. If you have to wear contact lenses, you should not only pay attention to cleaning every day and removing them during sleep, but also try to reduce the wearing time as much as possible., Contact lenses, also known as corneal contact lenses, are lenses worn on the cornea of the eye to correct vision or protect the eyes. More and more people join the contact lens group. Some myopic people wear them for the convenience of daily life, while others wear them for beauty. However, do you know that wearing contact lenses incorrectly and some incorrect habits will not make your eyes bright, but will hurt your soul. Do you know the dangers of wearing contact lenses?, What are the hazards of wearing contact lenses: 1. The resistance of the eyes decreases. Contact lenses will prevent the cornea from contacting the air. The eyes will produce a situation similar to human “altitude reaction” due to hypoxia, unable to metabolize normally and reduce the resistance., Expert advice: do not wear it to sleep. The cornea of the eye is a very special organ. There are no blood vessels on it. Its breathing is realized by means of air and surrounding tissues. If you sleep with glasses, it will affect its breathing. If it is serious, it may lead to corneal infection!, The second thing that wearing contact lenses does harm: it leads to visual fatigue and dry eye. Wearing contact lenses for a long time is easy to produce visual fatigue and even dry eye. Cause itchy eyes, foreign body sensation, eye excrement, dryness, burning eyes and blurred vision.,
contact lenses, also known as corneal contact lenses, are lenses worn on the cornea of the eye to correct vision or protect the eyes. More and more people join the contact lens group. Some myopic people wear them for the convenience of daily life, while others wear them for beauty. However, do you know that wearing contact lenses incorrectly and some incorrect habits will not make your eyes bright, but will hurt your soul. Do you know the dangers of wearing contact lenses?
one of the things harmful to wearing contact lenses:
eye resistance decreases.
contact lenses will prevent the cornea from contacting the air, and the eyes will produce a situation similar to human “altitude reaction” due to hypoxia, unable to metabolize normally and reduce resistance.
and
experts suggest that you should never sleep with your clothes on. The cornea of the eye is a very special organ. There are no blood vessels on it. Its breathing is realized by means of air and surrounding tissues. If you sleep with glasses, it will affect its breathing. If it is serious, it may lead to corneal infection!
and
what are the hazards of wearing contact lenses? 2:
and
lead to visual fatigue and dry eye disease.
and
wear contact lenses for a long time, which is easy to produce visual fatigue and even dry eye disease. Lead to itchy eyes, foreign body sensation, multiple eye excrement, dry sensation, burning eyes and blurred vision.
and
experts suggest that the main index of water content should be selected for contact lenses. If the water content is too high, the lens will absorb water from the eyes, causing discomfort and easy to dry. If the water content is too low, it will cause poor oxygen permeability of the lens, and the eyes are easy to feel dry, because the oxygen is transmitted through the water in the lens. Therefore, the ideal water content is between 50% – 60%.
and
three things harmful to wearing contact lenses:
and
cause eye allergy.
and
contact lenses adsorb protein, lipid and collagen in tears, make them deposit on the lens surface, breed bacteria, corneal edema, corneal neovascularization reaction and allergic reaction.
and
experts suggest that during the use of contact lenses, the components, secretions, impurities or foreign matters in the external environment in human tears inevitably adhere to the lens to form deposits. Even if nursing and cleaning are carried out strictly according to the process, there will still be deposits invisible to the naked eye that cannot be removed on the lens. It is recommended to use monthly polishing or replacement contact lenses with a shorter cycle than monthly polishing.
and
what are the hazards of wearing contact lenses? 4:
and
wear the cornea and cannot be corrected. The
and
contact lenses wear the cornea, which may cause serious consequences of corneal epithelial abscission or perforation. The concavity of some contact lenses is inconsistent with the corneal convexity. They wear the cornea irregularly, causing corneal ulcer and irreversible visual loss. Even after treatment, white spots will be left on the cornea. Experts of
and
suggest that the small scars on the lens are of different depths, which will cause irritation to the eyes and damage the corneal surface. It is necessary to ask an ophthalmologist to judge whether the lens should be replaced. Some small shallow scars on the surface of hard contact lenses can be repaired by grinding, but soft contact lenses cannot be repaired.
and
five things harmful to wearing contact lenses:
and
cause eye meridian paralysis.
and
contact lenses are attached to the eyeball for a long time, which will paralyze the nerve endings and lead to decreased corneal perception. Many patients are unaware of ulcerative keratitis. Experts from
and
suggest: go to a regular hospital or glasses fitting institution for detailed examination, select contact lenses suitable for your own wear, pay attention to eye hygiene and avoid other eye symptoms. If your eyes are red and dry, painful and afraid of light, and your vision drops during the process of wearing contact lenses, you should go to the hospital for examination in time.
the harm of wearing contact lenses 6:
corneal aging accelerates
if you wear soft contact lenses from the age of 20, the corneal endothelial cells will be greatly reduced five years later. After water intrusion, it is very easy to cause corneal edema. 10 years later, the density of corneal endothelial cells is equivalent to that of the elderly aged 60, so you will not be able to withstand any ophthalmic surgery, Even if cataracts occur in old age. Experts from
and
suggest that early myopia should wear frame glasses or laser vision correction surgery as much as possible.
warm tips: in these cases, wear less contact lenses,
spa, take a hot spring
when the weather turns cold, many people will think
