Eyeglasses for Eyestrain

If you work long hours at a computer, you are probably no stranger to eye strain in Charleston. This is an actual condition called computer vision syndrome (CVS) that can cause blurry vision, eye irritation, headaches neck pain and back pain.

Causes of Computer Vision Syndrome

CVS is like a repetitive stress injury that can worsen over time.

•     Looking down at the keyboard and then back up to the monitor strains the eye muscles due to the constant shift of focus.
• If you choose not to wear your prescription lenses as you work (to correct nearsightedness or astigmatism), you will be forced to strain to see the monitor clearly.
• If you do not keep your lens prescription up-to-date, you may be adding to the eye strain.
• The onset of presbyopia (the need for reading glasses) beginning around age 40 can make it more difficult to focus on the computer monitor.  
• Workstations that are not ergonomically-designed may cause you to crane your neck, slouch or arrange your body in an awkward position to compensate.

Look cool in your cubical!

Special computer glasses featuring lens coatings and tints that reduce glare can help to reduce the symptoms of CVS. These glasses can be purchased in non-prescription versions or in versions that support your specific refractive error. Before you invest in these glasses, be sure to read reviews online so you can make the best decision; these glasses don’t work for everyone.

Not surprisingly, prescription computer glasses cost more than non-prescription glasses. And if your prescription changes frequently, you will need to invest in new glasses regularly.

One way to combat the ongoing expense of glasses, contact lenses and cleaning solutions is by investing in the one-time cost of LASIK vision correction in Charleston. Dr.O'Day at Charleston Cornea and Refractive Surgery can determine if your eyes are right for LASIK during a free LASIK Consultation. 

Other Ways to Control Eyestrain

•  Every 20 minutes on the computer look at something 20 feet away for 20 seconds. This is known as the 20-20-20 rule.
•  Set a timer to remind yourself to take breaks from your screen (it’s easy to lose track of time when you are focused!)
•  Identify and implement the right ergonomics for your computer workstation by visiting the OSHA website.
• Adjust the brightness and contrast of your computer monitor and reduce the glare on your screen from lights or windows.

20/20 doesn’t mean an end to 20-20-20

Even if you have a successful LASIK procedure at Charleston Cornea and Refractive Surgery and achieve 20/20 vision, it’s still important to practice the 20-20-20 rule! CVS can affect anyone who sits in front of a computer for long periods of time.

Alcohol’s Effects on Night Vision

We all know that alcohol impairs judgment and coordination and slows reaction time.

But here is yet another reason to cut back on your alcohol consumption: A study coming out of the University of Grenada has shown that overconsumption can also adversely affect your night vision. The study examined 67 subjects who had consumed various quantities of wine. The researchers used a “halometer” visual test to determine the level of night vision disturbances and optical image quality. What they found was that the greater the breath alcohol content level, the greater the visual disturbance.

Why Alcohol Affects Vision

Alcohol disturbs the tear film that covers the surface of the eye. The ethanol (intoxicating agent) present in alcoholic drinks disturbs the outer tear film layer, causing the aqueous part of the tear to evaporate. When tear film is disturbed, the image quality that forms on the retina is also negatively affected, leading to the presence of halos and other visual disturbances in night vision.

Pre-existing Vision Conditions

Now add into the equation a pre-existing vision condition, such as nearsightedness, farsightedness or astigmatism. If your vision is already impaired due to a refractive error and you consume alcohol, the tear film disturbance combined with poor choices (such as not wearing glasses or contacts) can lead to disastrous consequences for yourself and others. LASIK vision correction in Charleston can correct these types of refractive errors, but even having 20/20 vision will not reduce the negative effects of alcohol on your vision.

In the past, some LASIK patients also complained of night vision problems after their procedure; however, today’s LASIK technology has effectively reduced this type of complication of LASIK. To learn more about Charleston LASIK and find out if you might be a good candidate for the procedure, contact Charleston Cornea & Refractive Surgery at 843-856-5275 or charlestoncornea.com. And whether or not you have LASIK, please never drink and drive.
