Uncomfortable wearing contact lenses!! Don t dare to wear contact lenses!

Crypto glasses – not for everyone.

Invisible glasses, as the name suggests, are "stealth". It not only has the function of ordinary glasses to correct vision, but also relieves the inconvenience caused by glasses, so wearing hidden glasses has become a fashion for today's teenagers. However, contact lenses are not suitable for all people who need glasses, so who should not wear them?

Primary and secondary school students are in a period of vigorous growth and development, the visual axis of the eyeball has not yet been shaped, if too early or a long time to wear contact lenses, it is easy to produce corneal hypoxia and physiological metabolic disorders. If the lens is not cleaned and disinfected strictly, secondary infection will occur; If the curvature of the lens is not suitable for the cornea, it will also cause corneal wear, epithelial detachment, and in severe cases, corneal ulceration or perforation. Therefore, if there is no special need for primary and secondary school students, it is advisable to wear glasses.

People with colds often carry a large number of germs on their hands, which can easily get into their eyes when they take or wear contact lenses. In addition, colds are often accompanied by mild inflammation of the retina, which can be exacerbated by wearing hidden glasses. Many cold, cough, and pain medications contain ingredients that suppress tears.

Reduced tear production can make the contact lenses too dry and less transparent, which in turn can affect vision.

Allergy patientsPeople with allergies are prone to complications caused by wearing contact glasses, such as slight inflammation, itching, redness, conjunctivitis and swollen eyes. If these conditions are not used for a long time, they can be dangerous to vision. If you have allergies and must wear contact lenses, it is best to use them only during the day and stop using them at least one day a week.

If inflammation occurs, it is best to discontinue use. If the inflammation does not subside after 2 to 3 days, you should go to the hospital immediately.

Patients with glaucoma, chronic dacryocystitis, conjunctivitis, corneal ulcers, hyperthyroidism and other diseases should wear them after the inflammation disappears if they are already equipped with contact lenses and their eyes are in the inflammatory phase.

When the local resistance of the eyes decreases and the secretion of tears decreases in fever patients, Bacillus subtilis will multiply in large numbers, so that the metabolites of bacteria are deposited between the cornea and the lens, resulting in the reduction of oxygen permeability of the contact glasses, and the normal metabolism of the cornea is disturbed, thus causing bacterial corneal ulcers.

When long-distance cyclists ride long distances, the convection of the air accelerates, so that the moisture of the soft contact glasses decreases, and the lenses gradually dry and harden, and the eyes will feel uncomfortable, and over time, the hardened lenses will damage the cornea, causing eye pain or bacterial infection.

After the age of 40, there will be more obvious degenerative changes in the eye tissue. If a thin layer of lenses is worn on the surface of the eyeball, it will lead to hypoxia of the eyeball, which will lead to corneal infection, ulcers and other complications. Middle-aged people between the ages of 40 and 60 can wear contact lenses for a short time, and the elderly over 60 years old should not wear contact lenses, otherwise it is easy to cause serious complications and cause permanent vision damage.

I also have tactile glasses.

But it's not as serious as you say.

Are your glasses reversed? If your eyes are dry.

Just go to the place where you have glasses and buy a small bottle of eye drops with hidden glasses.

It's not okay to moisturize. You can't buy blindly.

Also, it is best not to wear these glasses for more than 12 hours.

If I bring it, I will take it with me when I go out in the morning. Go home at noon and take it off, and go out in the afternoon with it.

I go home at night and take it off.

It's better to bring a 5 or 6 hours.

It would be nice to practice a few more times·· You should have just started bringing it... After a long time, you will become a veteran... Rest assured...

Long-term wear can affect eye health.

It can be matched, but it is necessary to pay attention to disinfection to prevent cross-infection Bausch & Lomb is recommended.
