Wearing medical devices at night Contact lens, probably leads to vision loss.
In order to correct vision or for cosmetic or therapeutic reasons, people tend to use contact lenses. A thin lens placed directly on the surface of the eye, considered as medical device. Others wear contacts lenses for functional or optical reasons, however an overnight use or wearing contact lens while at sleep may turn to blindness.
Using contact lenses must have prescription by ophthalmologists, optometrists, or specially licensed opticians under the supervision of an eye doctor to avoid infections. It has been found out, contact lens while at sleep decrease vision and later to blindness. While asleep, oxygen supplied from the blood vessels in the back of the eyelid, lens interferes with the passage of oxygen to the cornea can cause corneal hypoxia. This can result in many complications, including a corneal ulcer, which has the potential to permanently decrease vision.
Chad Groeschen, a 39 year-old builder and sculptor in Cincinnati, Ohio, diagnosed by Doctors at Cincinnati Eye Institute after a week of sleeping with extended use contact lens. He developed a corneal ulcer infected with Pseudomonas bacteria, quickly destroying his cornea, eye’s protective outer layer.
Thomas Steinemann, a clinical spokesman for the American Academy of Ophthalmology said, The lens case can get dirty, and germs from the case get onto the lens or vice versa, and eventually they get onto your eye and attack your cornea,”While sleeping in contacts or “topping off” the solution in the case instead of dumping it out, may seem like a small infraction, it can cause devastating eye infections and even blindness.”
An improper use of contact lenses may affect the eyelid, conjunctiva and the various layers of the cornea. Wearing contact lens while at sleep not approved for extended wear, common cause for complications. A habit can risks permanent damage to the eye and can be very unsafe and potentially cause permanent damage to the eye and loss of sight.
Centers for Disease Control and Prevention study, found out people choose not to follow rules, which
can lead to serious vision and health consequences. In statement of Dr. Jennifer R. Cope, medical epidemiologist at the CDC, “We think that there’s an event where maybe you seed the contact lens or your case with one of the microorganisms that can cause infection and then subsequent behavior can allow that to amplify so it’s causing an infection.” Showering in lenses or not replacing contact lens solution could seed the bugs, then wearing lenses for too long could allow them to amplify.
To insure safe use of lens, user must consult ophthalmologists especially when wearing contact lens while at sleep and to find out if patient’s eyes are still healthy enough to support contact lens wear.
If discomfort occurs, look for eye specialist to rule out potentially serious complications. In order to prevent more eye damage, contact lens wearers must observe proper hygiene. Regular wash hands, specially before touching their lenses and to remove contacts before showering, swimming and avoid wearing contact lens while at sleep. IMAGE/Cincinnati Eye Institute
