diopter

Head to Costco and buy three three packs of the diopter strength you loose.

I'm in the -7 diopter range, so the correction has to be pretty strong.

If it's so accurate, how did I end up an entire diopter off target?

Even cheap dslr cameras have a small +/-3 diopter adjustment in the eyepiece.

Couple of questions for those with Glass:Do they work with eyes older than 40 - those that can't focus within 18 inches without multi-diopter help?

I saw this film recently and thought it had a very interesting style, especially the shots using a split focus diopter.

Before that I had ~6 diopter short-sightedness in both eyes, with slight astigmatism.

The base value in my calculation is a regular prescription, so adding one diopter would put it in the area of a reading glasses prescription.

> I thought the diopter adjustment could compensate for glasses?The problem I had when I tried it was that I could get everything looking perfect through the viewfinder, but the resulting picture was blurred.

A couple of years later I realized that my formerly amblyopic eye suddenly sees almost as well as the nonamblyopic one. I suspect the fact that my amblyopic eye was unwittingly overprescribed by 1 diopter might have played a role by giving it an advantage for reading even when not using an eyepatch.

I commented to a colleague that the device would benefit from some sort of corrective adjustment of the optics, such as the "diopter" and "pupillary distance" adjustments in a high quality microscope.
