COMPUTER VISION SYNDROME

As we enter the 21st century, the growsing use of computers in the home and office brings with it an increase in health risks, especially for the eyes. One eye problem, called Computer Vision Syndrome (CVS), is afflicting more and more people who find themselves constantly in front of computer screens. While eye health professionals have yet to find CVS as a cause of any permanent eye damage, the pain and discomfort associated with the problem can affect workplace performance or the enjoyment of home activities. With a few preventative measures, however, the symptoms associated with CVS can be easily erased. The General Ophthalmology Service at Scheie Eye Institute offers many techniques for preventing CVS.

Percentage

Computer vision syndrome (CVS) is the most common 21st-century occupational hazard, which affects more than 70% of all computer users . CVS is a serious public health issue that results in decreased workplace productivity, higher error rates, lower job satisfaction, and compromised visual ability.

HYPERMETROPIA

Long-sightedness, also known as hypermetropia or hyperopia is a common vision disorder. It results from the overall power of the eye not being strong enough, or the length of the eye being too short. Surgical correction is a treatment option for hypermetropia, including laser eye surgery and clear lens exchange.

Percentage

The prevalence of hyperopia was 46.9% and higher in women (51.8%).The prevalence of hyperopia increased from 29% for 40-49 years of age to 65% for 50-59 years of age and tended to decline thereafter.

Myopia

Nearsightedness (myopia) is a common vision condition in which near objects appear clear, but objects farther away look blurry. It occurs when the shape of the eye — or the shape of certain parts of the eye — causes light rays to bend (refract) inaccurately.

Percentage

br>myopia was 21.9% but higher in men (25.0%).

PRESBYOPIA

Presbyopia is the gradual loss of your eyes' ability to focus on nearby objects. It's a natural, often annoying part of aging. Presbyopia usually becomes noticeable in your early to mid-40s and continues to worsen until around age 65.

Percentage

The prevalence of presbyopia has been estimated at nearly 80% by age 45–55 in North America with an estimated 16% of these individuals without adequate correction.

CATARACT

A cataract is a cloudy area in the lens of your eye (the clear part of the eye that helps to focus light). Cataracts are very common as you get older. In fact, more than half of all Americans age 80 or older either have cataracts or have had surgery to get rid of cataracts.

Percentage

They typically develop after age 55, but younger patients can be affected as well, including some infants at birth. About 18% of Americans aged 40 or older (more than 25 million people) have a cataract in one or both eyes

AMD

Age-related macular degeneration (AMD) is an eye disease that can blur your central vision. It happens when aging causes damage to the macula — the part of the eye that controls sharp, straight-ahead vision.

Percentage

Two forms exist: Dry (atrophic) AMD: is generally slowly progressive and is the most common. It causes moderate to severe visual loss (fig 1). Wet (exudative) AMD: accounts for 10% of AMD but results in 90% of blindness.

GLAUCOMA

Glaucoma is a group of eye diseases that can cause vision loss and blindness by damaging a nerve in the back of your eye called the optic nerve. The symptoms can start so slowly that you may not notice them. The only way to find out if you have glaucoma is to get a comprehensive dilated eye exam

Percentage

Anyone may develop glaucoma, but the incidence increases with age. About 1 in 10,000 babies are born with glaucoma, by age 40 about 1 in 200 have glaucoma, rising to 1 in 8 at age 80

ASTIGMATISM

Astigmatism (uh-STIG-muh-tiz-um) is a common and generally treatable imperfection in the curvature of the eye that causes blurred distance and near vision. Astigmatism occurs when either the front surface of the eye (cornea) or the lens inside the eye has mismatched curves.

Percentage

Astigmatism is measured in diopters. A perfect eye with no astigmatism has 0 diopters. Most people have between 0.5 to 0.75 diopters of astigmatism. People with a measurement of 1.5 or more typically need contacts or eyeglasses to have clear vision

DIABETIC RETIONAPATHY

Diabetic retinopathy is an eye condition that can cause vision loss and blindness in people who have diabetes. It affects blood vessels in the retina (the light-sensitive layer of tissue in the back of your eye). If you have diabetes, it's important to get a comprehensive dilated eye exam at least once a year.

Percentage

time, about 1 in 15 people with diabetes will develop DME. DME happens when blood vessels in the retina leak fluid into the macula (a part of the retina needed for sharp, central vision).
