- I have been sufferring from myopia since my college days and now at age 43 it
- still is progressing. It has been my experinece that after each increase in
- the lens prescription, my eyes accomodated and my vision deteriorated
- further. This vicious cycle continued each year until I took matters into my
- own hands. I decided to only use the full correction for distant vision
- switching off to the old prescription for reading and other close work. When
- I brought this up to the opthomologist, he stated that this was a futile
- excercise and that I would not suffer a greater degree of myoipia by doing
- close work with the new lens. There seems to be a dicotomy of opinion as to
- whether or not doing a lot of close work aggrevates myopia. All the
- opthomologists that I have consulted reject this concept, but the
- optomotrists agree with my layman diagnosis. As an additional data point, I
- also suffer from amblyopia in one eye and the degree of myopia in that eye is
- negligible compared with the other eye ╨ the one that I essentialy use. It
- seems that the opthomoligists are mainly concerned with eye disease and not
- preventative measures against myopia. My optometrist's suggestions make sence
- to me: Be careful not to focus in on close objects for prolonged periods of
- time, look up periodicaly and focus on distant objects. Do not use the full
- correction for close work.

- What is the bottom line here? How do you explain an increase in myopia in an
- adult? My uneducated hunch is that this is a muscle related problem (the eye
- isn't getting any longer at this stage). When pressed for an explanation, my
- opthomologist stated that the lens of the eye can become thicker with age and
- that this was a possible explanation. He gave me a thorough exam and ruled
- out degenerative myopia. I have great fears that after submitting to this 1
- diopter increase I will find myself in his exam room next year only to have
- this conversation once more. I would appreciate any feedback on this topic or
- the name of a good specialist in the Boston area. I have researched the
- surgical procedures for correcting myopia and understand that the results are
- not conclusive.
