ohhhh i have astigmatism.
i'm not really sure what it means, but i checked it up on the dictionary and it say:
1) also called astigmia,
ophthalm. a refractive error of the eye in which parallel rays of light from an external source do not converge on a single focal point on the retina.
2) optics. an aberration of a lens or other optical system in which the image of a point is spread out along the axis of the system.
i still don't know what it means -.-
