6 possible hazards of contact lenses

Abstract: 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.

more and more people are involved in the army of contact lens families. Some nearsighted people wear them for the convenience of daily life, while others wear them for beauty. However, you may not know that wearing contact lenses incorrectly and some incorrect habits will not make your eyes bright, but will hurt your soul window. Experts detail the hazards of 6 kinds of contact lenses for you.

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!

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

four things harmful to wearing contact lenses:

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: for early myopia, wear frame glasses or laser vision correction surgery as much as possible, or go to multi viewpoint Health Vision Center for three-dimensional therapy and physiotherapy.

warm tips: in these cases, wear less contact lenses.

spa, hot spring

when the weather turns cold, many people will think of going to the hot spring or spa to say goodbye to the cold… But it is recommended not to wear contact lenses when doing these similar spas, hot springs or steam baths. Because the contact lens contains water, the lens is easy to dehydrate at high temperature, resulting in the lens sticking in the eye and difficult to remove, which will also have some adverse effects.

and

do not wear contact lenses when swimming or after makeup. It is best not to wear contact lenses for menstrual women and pregnant women. If you must wear contact lenses, in addition to cleaning every day and removing them during sleep, you should try to reduce the time of wearing glasses. Don’t wear contact lenses when using the computer.

and

contact lenses are made of polymer materials. The oxygen permeability effect is not good, which will hinder the eyes from breathing oxygen directly and cause damageCorneal hypoxia. When facing the computer for a long time, the tear secretion itself has become less, and wearing contact lenses will make it worse. If you don’t develop good hygiene habits at this time, it is more likely to cause keratitis and corneal ulcer. In severe cases, it will also cause eyelid spasm and eventually affect your vision.
