Few days ago, we have posted regarding Alice (F/45) a full-time contact lens wearer who does computer work most of the time, complained blurry near vision with her contact lenses.
Alice was wearing toric lens that corrects shortsighted & astigmatism power. Now that she has reading power (or we call presbyopia), she needs additional reading power to support her near work. We have modified her prescription so that she is able to see near, to do her computer work. Her right eye has lesser astigmatism, so we prescribe a multifocal lens without astigmatism correction on this eye while maintaining a toric lens on her left eye. We explained the options available for her in order for her to see her computer work.
Now, we prescribe monovision for her, in which one eye is optimised for far vision (left eye) and the other eye is optimised for near vision (right eye). Is it always successful this way? As each individual is different, everyone has different needs & expectation. For Alice, she emphasises on her near vision as she looks at computer at work most of the time and she wants to continue wearing contact lens. With this monovision, she may not find her far vision as fantastic as her previous toric lens fitted on both eyes, but in return she will gain her near vision. So long as her far vision is still satisfactory to her, then it is all good! As her reading power is still low, monovision works great! But as her reading power gets higher, it means that monovision will give a bigger power difference between two eyes. Our eyes normally can tolerate up to a certain amount of power difference between two eyes, beyond it may not be as comfortable as before.
Alice has tried on the contact lenses for a week now. Happy to know that monovision works for you Alice in which she said so far no problems.. awww.. i truly appreciate your feedback yesterday????
Thank you Alice and hubby Mr Chan for your trust & support!????
