The Mono-vision Myth

Picture
With baby boomers  surpassing their mid forties, the bifocal issue has arisen in large numbers. Some do not like bifocals with or without a line and contact lens bifocals are difficult to fit and are always compromised.

Picture
One answer is mono-vision in contact lenses or LASIK. The dominate eye, is designed for driving and the other for reading - a modification of the antiquated monocle. This resolves the cosmetic problem of bifocals, the need to switch between two glasses, and difficult to fit compromised contact lenses. That sounds great, but are there problems?

Pictureflight 554
First, is it safe? The FAA does not think so, and will not let pilots fly with mono-vision because of the reduction in depth perception that affects 100% of mono-vision patients. The October 19,1996 Delta Airlines Flight 554 crash at LaGuardia Airport in New York has been attributed to the pilot's mono vision.




Picture
Are mono-vision doctors trained in binocular vision (the use of two eyes working together)? Either they are not trained or are ignoring basic physiology which they were taught in college. No doctor trained in binocular vision would recommend mono-vision except in the rare case of individuals who already only use only one eye at a time and can't be helped with vision therapy. That lack of training can lead to the wrong eye designated for driving. Not everyone who is right handed is right eye dominant, so a dominance test must be conducted.

Picture
What could happen to those who are prescribed mono-vision? All are an automobile accident waiting to happen. For mono-vision to work a person must suppress one eye. Thus, information will be missed (not good for work, sports, or study). Fatigue and nausea in reading may take place. Comprehension will be reduced. Sports skills will diminish or one will have to work harder to achieve the same level. Irritability is likely. Headaches and stomach aches may show. They may become strong willed and or argumentative. One eye may follow the direction of the mono-vision and a stronger prescription may be needed. Oh, yes, 3-D movies are out. Even if mono-vision is dis-continued vision therapy may be necessary to get the eyes to work as a team again. See Judy's story in success stories

If you or anyone you know has been prescribed mono-vision, reach Dr. Henshaw as soon as possible and get on the road to efficient comfortable vision
