What prescription is legally blind?

What Eye Prescription is Considered Legally Blind? Simply put, if your prescription is -2.5 or lower, this means that you are legally blind. Visual acuity of -2.5 is equivalent to 20/200 vision. Visual acuity of -3.0, for instance, means that you have 20/250 or 20/300 vision.

What do images look like with astigmatism?

Astigmatism is a common form of visual impairment in which an image is blurred due to an irregularity in the curvature of the front surface of the eye, the cornea. In astigmatism, the curve of the cornea is shaped more like an American football or a rugby ball rather than a normal spherical basketball.

Do people with astigmatism see lines in lights?
