many, many many threads here about this. you should spend a few hrs and read them. but to answer your question...NO, not really. almost all multifocal lens designs are designed for and only work well when inserted into BOTH eyes.
so no. it probably wouldnt work well.
so no. it probably wouldnt work well.
Go get 3 opinions/exams and see for yourself.
The key to my one eye success (I think) is that I have been a very successful contact lens wearer for over 30 years. I normally wear my one lens daily from the time I wake till I go to bed. I can tell you that wearing glasses (with one lens removed) does not work for me at all.
Thus, the answer to your question depends (In my opinion) on how nearsighted or farsighted you are, and how well you tolerate contacts all day, every day.
Question,could you please explain why a multifocal lems would be fine outside, but blur when indoors.
Answer, depends on the multifocal. The culprit in blurring vision is the magnification that in inherent in multifocal - Rezoom, or Bi-Focal - Restor. You are describing blurring in low light conditions which requires me to speculate that you are referring to the ReZoom. The ReZoom has a standard monofocal center, the magnification used to help you read is on the periphery. When you move indoors light is reduced and your pupil enlarges bringing into play the magnification located on the periphery of the ReZoom. From an engineering standpoint this makes a lot of since because all of us need help at near in low light as we get older. However when the pupil enlarges you now have light coming thru 2 optical powers, the distance power in the middle of the lens and the magnified light thru the periphery, this leads to blurring in some patients, not all. Hope this helps and yes I am a crystalens supporter, no apologies for that.
