Because reading glasses are very weak and are meant to account for age related vision loss which is typically mild but degenerative.
As someone with eye shape hyperopia (just the inverse of myopia), I’ve never had a prescription weak enough to get otc glasses. Hell, many of us need special lens materials to prevent distortions (and unfortunately prescription safety glasses don’t have those options and so I get fish eye from them).
Reading glasses are super useful though for when I’m wearing contacts and need to do something small and precise.
ETA: hyperopia vs presbyopia Wikipedia articles. Farsightedness is about eye shape and is just the inverse of nearsightedness, while presbyopia is age related changes to the lens of the eye reducing it’s ability to focus.
