still wear contact lenses while sleeping, Secure?

As a contact lens users, perhaps you've one or two times asleep still wearing box. Most did not intentionally, for example asleep in front of the TV or forget to bring a soft lens cleaning fluid while staying elsewhere.

However, there are also people who quite often sleep without removing contact lenses for practical reasons. This habit should not be continued because it is dangerous to the health of the eye.

Sleep with still wear contact lenses will make corneal oxygen deficiency. "It's like sleeping with a plastic bag to cover your head," said Dr. Rebecca Taylor, spokesman for the American Academy of Ophthalmologists (AAO).

As long as we are awake, the cornea will receive oxygen from the air. Meanwhile, when asleep, Korena will get nutrition and lubrication of tears and ciran gelatinus called the aqueous humor. If we fall asleep with contact lenses have not been released, there will be a barrier between the eyelid with the cornea. Moreover konta lens cover almost the entire surface of the cornea.

"When we are awake and blinking, contact lenses should be shifted approximately one millimeter so that the cornea is able to receive oxygen. However, contact lenses while sleeping can not move because the eye does not blink," said Taylor.

Other adverse impact is infection. Slightest friction between the back of the contact lens in contact with the cornea can cause bacterial or parasitic infections. Microorganisms can be carried away by contact lenses before use.

"Bacteria that can be carried as a contact lens is dirty or worn too long. Even through clean water potable though," he said.

Parasites were found in the water, among others, Acanthamoeba that can cause eye infections. Another danger is corneal ulcers or sores in the outer layer of the cornea. A Taiwanese woman reportedly blinded by using contact lenses for six full months.

In 2012, research in the journal Ophthalmology showed that the risk of keratitis (inflammation of the cornea) will increase 6.5-fold due to using contact lenses during sleep. This will not happen if the users to remove contact lenses before bed.

Indeed there is a contact lens on the Agency permits the US Food and Drug Administration (FDA) may be used several days in a row. However, Taylor and the FDA itself recommends to not use up all night and let go of at least once a week.

AAO research, people who use contact lenses soft hydrogel (type of contact lens wear resistant days) had a risk of 10 to 15 times higher than the inflamed ulcer regular contact lens wearers.

"Wearing any type of contact lens-all night semalama increase the likelihood of infection of the cornea," according to the AAO.
