Monovision laser eye surgery?
I am shortsighted (around -2) and am finally (I'm 55) considering having my eyes corrected with laser / Lasik surgery. At the consultation, I was told the best thing for me would be monovision, ie just one eye corrected to 20/20 vision, the other left as the reading eye, only the astigmatism would be corrected. I have worn contacts with some monovision for years, but found reading a strain, as there was not so much difference in the correction. Now I have been given soft lenses to try out the monovision as it would be after the laser surgery. I find it really difficult to make up my mind. I seem to get on with it fine in everyday life, but worry about that I'll always feel my vision is not quite right. I can read ok, but what about reading over longer periods? I can drive, but it's not ideal. Monovision seems ideal for my work when teaching, but not when using the computer. Has anyone had any experience? What do you think?
Monovision delivers the best reduction in your dependancy on glasses. However, this depends on what you do with your eyes. Monovision is not considered a good option in some industries such as Cab/truck drivers, pilots etc.
The particular areas of concern for Distance Vision have been stated already : low light conditions (night driving), intermediate distances (PC, sometimes TV). Thus, how critical is your distance vision in such circumstances? Secondly, Monovision does not fully correct your need for Reading Glasses either, small print or print in low lighting will require a pair of Ready Readers.
Trialling bother full correction and the monovision correction in similar circumstances is the only way you will get to a decision. Perhaps spend a few days under normal working/living conditions with either to get a better idea.
