Seeing Eye To Eye
Computer Vision Syndrome (CVS)
Written By: Carrie Gaines | April 23, 2012
More than 50% of Americans spend 2 hours or more on a computer. Computer Vision Syndrome (CVS) describes a group of eye and vision-related problems that arise from extended periods of computer use.
Many of us who spend a great deal of time on the computer recognize and experience many of these symptoms:
- Difficulty focusing and blurred vision
- Dry, itchy, watery eyes
- Pain or muscle spasms in the neck and shoulders
Minor vision problems such as uncorrected nearsightedness, farsightedness or presbyopia can contribute to the development of CVS. Poor eye coordination and focusing skills can contribute as well.
Steps to manage CVS:
- Adjust text size so that it is three times the smallest text you can read from your normal working distance.
- Experiment with color choice. Black text on a white background works well for most but a light text on a dark background or other color combinations may work better.
- Adjust the brightness to match the room brightness. Then, increase the contrast to the highest comfortable level.
- Reduce glare:
- Position your monitor so that windows are to the side of the monitor.
- Do not shine a desk lamp on the screen.
- Consider using a glare filter over the monitor or a monitor hood.
- Use lubricating eye drops. And, remember to blink.
- Make sure to use proper “computer ergonomics”
- Position your monitor 20 to 26 inches away.
- Make sure your monitor is 4-9 inches below straight ahead gaze.
- Position your chair and monitor so that your arms are parallel to the floor while typing and your feet are flat on the floor.
- Use a document holder close to the screen.
- Finally, take a break. Either look away from the computer and even stand up or stretch.
- Take time to make your computer use as comfortable as possible.
It is a New Year!

Beware of Halloween Contact Lenses (on the internet)
Written By: Carrie Gaines | October 13, 2011
Halloween is right around the corner. Special effect and “circle-tinted” contact lenses popularized by the Twilight Saga movies and Lady Gaga are being sold on the internet. This is a concern.
The United States Food and Drug Administration (FDA) classified all contact lenses, whether they correct vision or are simply cosmetic, as medical devices in 2005. In the United States, contact lenses cannot be obtained legally without a prescription.
Contact lenses of all types obtained without a prescription and without appropriate fitting, training and follow-up present risks to the eye that include corneal abrasion, corneal ulcers, vision impairment and blindness.
If you want special effect contact lenses,
- Get an eye examination from an eye care professional.
- Get a valid prescription that includes the brand and the lens specifications.
- Buy the lenses from an eye care professional or a vendor that requires prescription information.
- Follow directions for wearing, cleaning, disinfecting and replacing the lenses.
- Visit your eye care professional for follow-up eye examinations.
- And, never share your contact lenses.
Help for Keratoconus – a true case story.
Written By: Carrie Gaines | March 25, 2011
William is a very intelligent and pleasant 34-year-old gentleman. He has had known keratoconus since 2006. The keratoconus was more severe in his right eye. With glasses his best vision was 20/150 in his right eye and was 20/25 in his left eye. Keratoconus interfered with his life. Images were multiple, distorted and blurred. His work suffered because he had difficulty using the computer and reading. He experienced glare and haloes around lights which made it difficult to drive both at night and in bright sunlight. William tried multiple contact lenses to manage his keratoconus. And although he could see reasonably well with contact lenses, they became intolerable after 4 to 5 hours.
Intacs corneal implants were recommended for William to restore his visual function. Intacs are micro thin. They work by flattening the steep part of the cornea resulting in improved vision and reduced vision distortions. Prior to Intacs, the steepest part of his cornea was 9.25 diopters in his right eye. Following Intacs, the steepest part of his cornea was 5.25 diopters and his vision improved from 20/150 to 20/30! Lastly, he was fit with a custom scleral contact lens to fine tune the vision in his right eye. He comfortably wears the scleral lens all day long and has the best vision that he can remember. Although William still has keratoconus, it is no longer a source of stress and no longer interferes with driving or work. Best of all, he is able to clearly see his new baby girl!
