Refractive error (hyperopia, myopia, astigmatism), in any spherical equivalent of worse than -8.00 or +8.00 diopters; if ordinary spectacles cause discomfort by reason of ghost images or prismatic displacement; or if corrected by orthokeratology or keratorefractive surgery. However, for entrance ...
They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them."...

These publications point to a statistically significant increase in the optical quality with SL even under challenging conditions. However, many factors could degrade the visual performance during SL wear that should be assessed appropriately – residual astigmatism, lens flexure, lens rotation, midday ...
The cleanup in vision was worth it. The scar-astigmatism could be fixed, either by working on the current cornea or transplanting. I’m not interested in either. Nope. Not gonna. The upside is that I can use a computer all day long without glasses. Non computer, I’ll use bifocals, ...
