Can Refractive Error Cause Styes?
MAR 10, 2014
No, but a large stye may be the cause of a type of refractive error known as "astigmatism." A larger form of a stye, called a chalazion, involves blockage of the oil glands of the eyelid (meibomian glands). If a chalazion gets large enough, it can press on the globe and cause an induced astigmatism. The astigmatism typically resolves as the chalazion is treated and resolves.
