Optional Nikon eyepiece diopters allow you to optimize your SLR viewfinder's sharpness in conjunction with your individual eyesight. Nikon SLR cameras (without built-in adjustable eyepiece correction) have a base diopter value of minus one. Minus one is considered the optimum starting point for the majority of SLR users with normal vision. The combination of the camera's viewfinder components and a clear (standard) eyepiece form a virtual image of a subject on the camera's focusing screen that is the approximate equivalent of a viewing distance of one meter.

Each Nikon eyepiece diopter incorporates a numerical value, represented by a minus value (nearsighted) or a plus value (farsighted) number, enabling you to select the appropriate diopter for your vision and your camera model.

The eyepiece's diopter value is, when combined with the viewfinders minus one value, the end-result value. No combination of the camera's base value of minus one and a given accessory diopter's value is required to arrive at the final desired value. In other words, if you require a diopter of plus 3, simply add a plus 3 diopter to your camera.

Comments about Nikon +0.5 Diopter for FM2/FE2/FA:

I got this for my FM3a, which I had read has a -1 diopter by default. Well since my eye only needs -0.5 I figured this would bring it down just right. It didn't. I'm not sure, but I'm guessing nikon labels these with the correction that results when adding the default -1 to it's own correction (which would be +1.5 then).

Either way, this will get no use from me, despite being of seemingly good quality.
