I have a question about the legally blind part

[Mike9241]

you weren't very specific it so this is from the 1040 instructions

If you weren’t totally blind as of December 31, 2022, you must get a statement  certified by your eye doctor (ophthalmologist or optometrist) that: 

• You can't see better than 20/200 in your better eye with glasses or contact lenses, or
• Your field of vision is 20 degrees or less.
If your eye condition isn't likely to improve beyond the conditions listed above, you can get a statement certified by your eye doctor (ophthalmologist or optometrist) to this effect instead.
You must keep the statement for your records.

for IRS notices and letters If you receive a notice or letter but you would prefer to have it in Braille or
large print, you can use Form 9000, Alternative Media Preference, to request notices in an alternative format including Braille, large print, audio, or electronic. You can attach Form 9000 to your return or mail it separately.
• You can download, or view online, tax forms and publications in a variety of formats including text-only, Braille ready files, browser-friendly HTML (other than tax forms), accessible PDF, and large print.
