Do you find studies that suggest astigmatism (high, asymmetrical, chromatic aberration etc) causing form deprivation thus progression of myopia when left uncorrected with or without correction of spherical refractive error?
I feel I ordered reading glasses (differentials) without astigmatism correction in vain. This is way too terrible to read at 50 cm from screen with uncorrected astigmatism somewhere about 2 diopters. Yes, I knew, it could be like that, but in time astigmatism was better by about 0.5 diopters, I read from screen at 30 cm just fine. However, 30 cm and 50 cm is a very big difference.
I neglected correction for 2 and 1.5 astigmatism for two months, then again for half a month, and it was not only not improve, but got worse to 2.5 and 1.63 with worsening of myopia. Could it be the reason?
Also, I am too tired with unstable vision (changing with each blink) contact lenses give me. While glasses would to be like Sph -9 Cyl -3.5, I am “tempted” to give spherical and cylindrical glasses a shot.
