Dear Charles,
It is also legal to buy blood-pressure measuring equipment
over-the-counter.
Thus if you check you B.P. and find 120/80 you indeed
have no problem.
It is also legal to buy plus and minus lenses and look
through them.
You can buy them on the internet (a pair for $10).
You can also find a Snellen on the internet.
If you are reading the Snellen at 20/70, and find
a -1.25 diopter minus lens "clears" the 20/20 line,
then that is indeed your refractive STATE.
The issue is this. Do you have the right to do this?
If you wished you could go to the OD and have him
check. His methods are the same a per above.
He will check for retinal problems (organic) and
the like. But once it is clear that a -1.25 diopter
will clear the 20/20 line -- then you do have a choice
in where you obtain that minus lens.
Given the availablity of minus lenses of various powers,
you could determine your own refractive STATE if
you choose to do so.
