If you wear soft contact lenses for astigmatism, don’t be surprised if your vision gets blurry when you watch television while lying on the couch. The problem? Your contacts are rotating out of position.
In order to correct astigmatism, toric soft contacts have different lens powers in different parts of the lens, with a design feature that enables the lens rotate and stabilize in a position so the correct lens powers are aligned in front of the appropriate parts of your eye.
Design features to maintain rotational stability include a thicker, heavier portion at one point in the lens periphery, “thin zones” in specific portions of the lens or a combination of both these features.
Researchers in the UK recently conducted a study of the effect of gravity and gaze direction on toric contact lens orientation and eye chart visual acuity. Read more…
