According to a new report released Thursday by the Centers for Disease Control and Prevention, a whopping 99 percent of wearers have engaged in at least one “contact lens hygiene risk behavior” known to increase the chances of developing eye infection or inflammation. And nearly one-third have had to visit a doctor because of eye redness or pain caused by their contact lenses.
Relying on market research, the CDC authors estimated that there are approximately 40.9 million Americans over the age of 18 who regularly use contact lens, 93 percent of which use soft contact lenses as opposed to rigid lenses.
Contact lenses are worn in “contact” with the eye. They are prescription lenses designed to correct vision errors, much like miniature eye glasses. They change where the light is focused on the retina, which improves your eyesight.3
These little lenses move with the eye and float on your tear film over the surface of your cornea. As far back as 1508, Leonardo da Vinci had illustrated the concept of contact lenses. The first lenses were made of glass in 1887.
The Importance of Full Spectrum Light
Your eyes need full spectrum light to stay healthy, just as your body needs sunshine. When light enters your eye it not only assists you to see but likewise goes to your brain’s hypothalamus.
This is the gland in your brain that controls your body temperature level, appetite, thirst, water balance and blood pressure.
It likewise has a considerable influence on your pituitary gland that produces numerous different necessary hormones. For this factor direct exposure to full-spectrum lighting is an effective therapy for treating anxiety, infection and more.
According to research study by Dr. Martin Mainster and Dr. Patricia Turner at the University of Kansas School of Medicine:
” Insufficient environmental light and/or ganglion photoreception can cause circadian interruption, increasing the threat of insomnia, anxiety, various systemic disorders and potentially early death.
Synthetic lighting is dimmer and less blue-weighted than natural daylight, adding to age-related losses in unconscious circadian photoreception.”
Studies have actually likewise demonstrated poor lighting is connected with headaches, tension, fatigue and stretched, watery eyes. Poor lighting is also related to bad work production.
Conversely, business that have changed to full-spectrum lights report enhanced worker spirits, greater performance, minimized mistakes and reduced absence.

In this five-minute video you’ll discover a few of the typical errors people make when they clean or keep their contact lenses. These mistakes can have serious consequences, consisting of infection and damage to your eye sight.
In a current news broadcast from ABC, Dr. William Faulkner from the Cincinnati Eye Institutes cautions that 20,000 people a year establish pseudomonas infections in their eyes. According to the Centers for Illness Control and Prevention (CDC) HALF of individuals sleep with their contact lenses on.
Unfortunately, these practices lead to an increased danger of infection in your eye, which might cause a devastating infection and loss of eyesight. Left untreated you may even lose your eye.
Faulkner relates that people who sleep in their lenses, even those marketed as over night contacts, have a 10 times higher risk of establishing an eye infection.
Nearly 1 in every 5 individuals with eye infections including contact lenses experience damage to their eye. These issues consist of scarred corneas, corneal transplants and loss of vision.
As far back as 1996, researchers determined numerous elements adding to increased threat of infection and corneal ulcers from sleeping in your contacts, including:
– oxygen deprivation
– bacterial survival
– patterns of sleep
– absence of eye and lid motion
– climatic pollution
Reports of infection and eye damage are monitored by both the CDC and U.S. Fda (FDA) as contact lenses are regulated by the FDA as medical devices. A high percentage of the reports included individuals utilizing over night or prolonged wear contact lenses.The CDC reports keratitis, or inflammation of the cornea, sets off over 1 million visits to the emergency situation room each year with an approximated direct medical cost of $175 million. Greater than 99 percent of the individuals surveyed reported they participated in at least one behavior that increased their risk of contracting an infection.
A different type of contact lens is used only at night in order to reshape the eye so the user does not need glasses or contacts the next day. This item has been used by young professional athletes to decrease their need for glasses or contacts while they’re competing. The lenses are called orthokeratology, likewise referred to as ortho-k.
The expense of these lenses can be high, but lots of moms and dads discover the pros exceed the cost. The practice of reshaping your cornea with contacts has been around for decades, however the FDA just first approved them for use in 2002.
These lenses are now normally marketed to teenagers and children by eye doctors. The lenses are used for kids with mild to moderate myopia with the hope that the lens will help in reducing refractive mistake over time. Nevertheless, wearing these lenses overnight come with significant dangers.
While a lot of kids experience short-term enhancements in their eye sight, some specialists think that by prescribing the lenses at a young age, improving of the cornea could become semi-permanent since the cells in children’s eyes divide more rapidly. This quick cellular division might lead to more permanent changes to the shape of the eye.
Eye doctors and corneal specialists are not so taken with ortho-k lenses, mentioning their experience and numerous studies for their issue. Sleeping with contact lenses, whether they are marketed as extended wear, as are ortho-k lenses, or if you unintentionally drop off to sleep in your lenses, increases your risk of eye damage.
Dangers Associated With Oversleeping Your Contacts
Wu Jian-Liang, the director of ophthalmology at Taipei’s Wan Fang Health center, estimated in the Daily Mail, states:
” Contact lens wearers are a high-risk group that can easily be exposed to eye diseases. A shortage of oxygen can damage the surface of the epithelial tissue, developing tiny wounds into which the bacteria can quickly infect, infecting the remainder of the eye and supplying an ideal breeding place.”
Typical threats include:
Wearing contact lenses reduces the quantity of oxygen readily available to your eyes. Every tissue in your body depends upon oxygen. In reaction, your body starts growing brand-new vessels, called corneal neovascularization. Extra blood vessels increase your threat of retinal damage.
Corneal microcysts and vacuoles also develop from chronic hypoxia. Normally you do not have symptoms but your eyes might get slightly irritated or you might experience hazy vision. Treatment is to stop utilizing contact lenses. Often times the condition is reversible when dealt with.
Hypoxia may also trigger contact lens intense red eye (CLARE) when high levels of gram negative germs take up residence under your lens after sleeping in your contacts. Treatment includes removing your lenses, anti-inflammatory eye drops and eye lubes. Antibiotics are not utilized as CLARE is the result of endotoxin reaction and not intrusive infection.
Corneal ulcers are open sores that form might form when contacts scratch the surface of the cornea and might trigger long-term damage. The scratches leave your eye available to infection. If something is left on the contact lens it can likewise scratch the cornea. Absence of oxygen from sleeping in the contacts can also leave the tissue more susceptible to ulceration.
The main parasite and infection discovered associated with contact lenses is Acanthamoeba keratitis. When you use your contacts during the daytime and night hours you keep the parasite in contact with your eye where it can feed upon the corneal tissue. Although it is relatively uncommon, it can lead to permanent structural damage to your eye and vision loss.
Showering and swimming in your contact lenses may increase your danger of parasitic infection. The acanthamoeba parasite resides in the water supply and doesn’t usually trigger other health issue. The parasite is likewise resistant to the majority of the contact lens disinfectants on the market, so cleaning your lens after swimming doesn’t minimize your risk.
Overusing your contact lenses is another element that might increase your threat of infection and damage to your eye. If you over wear your lenses they may become so thin they tear and scratch your cornea. Calcium and protein deposits can develop up, scratch your cornea and affect your vision.
You should constantly have the ability to rotate your lens in your eye. If your eye becomes dry and your lenses are not floating over your eye take them out right away. Clean and soak them while you give your eyes a rest. You can reduce the risk of over wearing by following these pointers:.
