Changing my prescription for safety glasses?

My prescription is SPH +1.75, ADD +2.25.

I want to get a pair of safety glasses that I will use only to look at
things within 5'.

Would it make any sense to change the prescription to SPH +2.5, ADD +1.5, or
something like that? Obviously that wouldn't be too good for driving, but
should be perfect for use in the shop.

I have an eye doctor appt next month; if it is a silly idea I won't bring it
up. Thanks.

It is an excellent idea, and several brands already offer solutions that do
that exactly that. Most often they are called computer lenses or
Office/Business lenses.

Zeiss makes two different ones: Gradal RD and Zeiss Business. Unfortunately,
they are only available is 1.50 plastic (not considered to be a safety
lens). Not sure about the lens materials that are available form other
manufacturers who offer computer lenses.

But your OD can make up a custom Rx that can be used with any lens model to
get close to what you want. Some opticians can take a regular Rx and convert
for you without a visit back to the OD (they may have to call the OD to get
permission depending on your state).

BTW, polycarb is the lens material usually used for safety lens, but tell
your Optician you want Trivex, which has much better optical qualities than
polycarb, and provides the same level of impact resistance and tensile
strength. Trivex is available from lens companies in such products as Hoya
Phoenix, Younger Image, Essilor Definity, Smamir Genesis, and a few others.

Now that I have given you some specific products to consider, search the
Internet and get more information before you visit your OD/Optician so that
you will be an informed consumer. Once they realize you know what you are
talking about, they won't try and BS as much.

You can say that again. My ordinary glasses are Trivex (since I often use
them as safety glasses even though the frames really aren't suitable) and
they are so much better than polycarb...

OK, I will say it again. Polycarb sucks for Rx lenses.

Personally, I haven't been able to find any manufacturer that make
"computer" progressives in Trivex.
But, both Younger Image and Hoya make a regular progressive in Trivex
if you don't mind the narrower corridor.
If you want the wider corridor provided by the "computer" progessives,
you'd have to go with the polycarb, of which two brands come to
mind... Sola Access and Shamir Office.

How is the corridor on the Younger progressives? Is it super narrow
like many regular progressives I've tried?
Was thinking of getting a pair of the DriveWear pros, but if their
corridor is real narrow I'll have adapt trouble as usual.

I'm not sure i can answer that. When I put on my first pair of bifocals,
they just worked. Either I am extremely adaptive, or estremely insensitive.
But sitting here and moving my head around and looking for blurry spots,
they seem really good. I will buy them again.
