Thank you Dr. Brown. I will make sure I am reading from the bottom portion of my trifocals. That very well could be the problem. Thanks again.
Trifocals are lenses that have 3 separate parts to them: top = distance, center = computer, bottom = reading. Your symptoms are caused by the fact that the extra power provided for your reading is not enough to give you stable up-close focus. It is possible that you are actually reading through the central part of the trifocal, not the bottom part. Pay attention to this and make an effort to read through the bottom of the lenses. If the problem persists, see an eye care provider for an updated prescription.
