Nikon -4 Diopter for Rectangular-Style Viewfinder
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 -4 Diopter for Rectangular-Style Viewfinder:
If you need glasses to see far away, this is a great way to get your eye closer to the viewfinder. Field of view doesn't seem to be limited by the lens frame, and it's easy to install and remove. I'd suggest asking your eye doctor (yes, I am one) if these diopter lenses will work for you--if you have too much astigmatism, or your near-sightedness or far-sightedness is beyond the range of these lenses, your image might not be sharp enough for what you need.

Allows me to work w/o eyeglasses. The built-in diopter adjustment doesn't provide enough range for my eyes. Would like it better if it had the rubber cup that the stock eyepiece has.
