It's a bad idea. I've seen patients who get eyeglasses online, and have
no idea how they made them or how they work. Where do these outfits get
thier measurements from when the patient was never measured, nor such
information put on thier Rx?
I emailed one such site, and asked how they went about measuring seg
heights for multifocals. Of course, I was ignored. If they are
confident in what they do, they would not be afraid to email me back.
Makes me wonder how they would treat an unsatisfied patient.

If you already have a properly-fitting pair you might send it along with your
order or take measurements yourself.
There is a standard height below the PD. I once wanted the segment higher and
was ultimately unhappy -- it made it easy to see the speedometer without
moving my head, but it got in the way the rest of the time.

I emailed Zenni with a question and the guy got back to me the next day. No
point in dealing with unresponsibe people.

There is a fine line between 'hobby' and 'mental illness.'
Who knows -- maybe Zeni will mass market a
trial-lens kit, and other supporting material to
assist in the measurement of PD and segment height.

If you've worn glasses before I don't think it's too difficult to figure out
either. So you're saying it's OK for me to wear glasses as long as I wear +
lenses?

Although some opticians/opt shops will use a formulaic method of
determining seg height, or pd, I still think it's a much better idea to
have it done by an eyecare professional. Not everyone can be fitted
with such general standards. In a well reputed optical shop, you will
be taken care of until you are satisfied, many people have different
preferences where they'd like thier seg height to be, and various
facial anomolies, and certain occupational considerations should be
taken. In the end, if it works for you, go for it, but be aware of any
risks involved and make sure they back up thier product. When it comes
down to it, it's the integrity of the optical shop, whether online or
off line.
