I am curious as to where the line is drawn for visual impairment to be considered “blind”.

For example, i am profoundly myopic and have a significant astigmatism in both eyes. Vision correction surgeries are not a viable option for me due to anatomy. Even when I’m wearing glasses or contacts with the proper prescription, everything is still fuzzy around the edges. I have a very difficult time seeing things that are pointed out to me within a couple feet. I’m blue eyed and incredibly sensitive to light, I almost cannot bear to be outside without sunglasses. My vision is still declining as I age with no end in sight. At what point am I truly considered visually impaired?

I would like to be clear that I am under the care of an amazing optometrist, so I am not seeking medical advice. I would just like to hear from the visually impaired community on how much further I have to go to consider myself such.
