Computer Vision

Squinting at computer, tablet, or mobile screens for hours at a time is a normal part of our lives in the 21st century. Unfortunately, eye problems associated with this activity are also on the rise. Even if you have never had eye problems before, you may have noticed computer vision syndrome symptoms after two or more hours of screen time. Signs include:

Blurry vision
Eye strain and discomfort
Headaches
Dry, scratchy eyes
Neck and/or shoulder pain

Even if your symptoms are mild, they can worsen and cause other vision problems if not addressed. Our optometrist, Dr. Nadel, can help.

Diagnosis and Treatment of Computer Vision Syndrome

The severity and length of computer vision syndrome symptoms depends on how long you stare at the computer, your posture, lighting, glare, the angle of the monitor, and whether or not you have other diagnosed or undiagnosed vision problems. If you already suffer from astigmatism, farsightedness, presbyopia, aging eyes, and/or diabetic eye problems, your computer vision symptoms may worsen. This can even be the case if you already have prescription contacts or glasses. Many regular eyeglasses and contact lenses are not designed to deflect the problems caused by computer screens.

Dr. Nadel will take your symptoms, pre-existing conditions, and potential undiagnosed conditions into account as he performs the following eye tests:

Visual acuity—Measures the quality of your current vision.
Refraction—Tests the potential lens prescriptions that would optimize your vision.
Focus and Eye Coordination—Tests how well your eyes work together and how quickly and accurately your eyes are able to focus on objects and varying distances.

From these measurements, Dr. Nadel can design a treatment plan to help relieve your symptoms. For people with otherwise normal eyes and vision, a set of specially-designed glasses used during the time you are working on the computer can be very helpful. For patients already wearing contacts or glasses, new, more computer-friendly prescriptions are available. In addition to these treatment options, there are many things we can suggest to cut down on computer eye strain problems:

Computer setup—Adjust your monitor so that it is about 15-20 degrees lower than your eye level when seated between 20-28 inches away from the screen. Reference materials can be placed on a document holder between the monitor and keyboard, or to the side, but positioned for as little head movement as possible. Also invest in an anti-glare screen for your monitor to help reduce glare from surrounding lights. Be sure to sit and work with proper posture.
Adjust Lighting—If you can, reposition any lighting (or your computer) to minimize glare and use natural lighting whenever possible.
Eye Rest and Blinking Breaks—Every 20 minutes during your work, look away toward a distant point for 20 seconds to refocus your eyes, and give them a 15-minute break after each 2-hour computer session. Also remember to blink more frequently to keep your eyes moist.

With a combination of the proper optometry care and self-care, you can minimize computer eye syndrome and other modern-day vision problems. Contact us for an appointment today.

Astigmatism:

Astigmatism develops when the front of the eye curves into a bulge or oval shape. It causes blurred vision and can be difficult to correct because regular contacts cannot account for the bulging.

Dry Eyes:

When eyes become excessively dry, it leads to irritation, burning, redness and blurred vision. Contact lenses can exacerbate these conditions by making it feel like a foreign object is stuck in your eye.

GPC:

This form of conjunctivitis is caused by inflammation on the inner surface of the eyelid. Protein buildup on contact lenses can make this condition worse.

Keratoconus:

This is an uncommon condition that causes major discomfort when wearing contacts. Keratoconus happens when the cornea becomes thinner and allows the eye to bulge forward. The bulge forms into a cone shape.

Presbyopia:

Eyes tend to have a tougher time focusing on close objects as they age. This condition is known as presbyopia. It typically affects people aged 40 or older.

Solutions for Hard to Fit Contacts

Wearing contacts is not impossible if you suffer from one of the above conditions. You do need to meet with an eye care professional, however, and get prescribed contact lenses that are tailored to deal with your specific vision condition.

Gas permeable lenses are a good solution for patients who suffer from GPC or Keratoconus. A GP lens will limit protein deposits from accumulating which will reduce GPC symptoms. It is also effective in containing corneal bulging and relieving pressure on the tissue for a Keratoconus sufferer.

Toric lenses are useful for correcting astigmatism. Since the lens needs to align with the bulge it is correcting, toric lenses must not rotate in order to fit on the eye. They are typically custom made to correct a specific astigmatism. For that reason, this type of lens takes longer to make and costs more than a traditional contact lens.

Bifocal and multifocal lenses can help remedy presbyopia. Monovision lenses are another option for presbyopia. This type of lenses can have one fitted for distance vision and the other for seeing close objects.

Medicated eye drops can be an effective solution for dealing with dry eyes. They will lubricate eyes enough to make contact lenses more bearable, although a punctual occlusion also must be done to plug the ducts in some extreme cases. GPC symptoms can also be lessened through medicated eye drops. They flush out protein deposits and reduce inflammation.
