Is 20 1000 vision bad?

Understanding Visual Impairment

A vision of 20/500 to 20/1000 is categorized as profound visual impairment or profound low vision. If visual acuity falls below 20/1000, it is classified as near-total visual impairment or near-total low vision. Conversely, a complete lack of light perception indicates total visual impairment or total blindness.
