Minus eight diopters? Minus ten? Worse? No doubt you have been on the receiving end of a long series of ever stronger prescriptions from your optometrist or eye doctor. As a severe myope, you probably also spent much time with your nose in books or too close to a screen, landing you on the extreme end of the myopia spectrum.

Strong minus glasses significantly compress objects in your field of view such that they appear smaller. The closer the lenses are to your eyeballs, the less compression happens. At the same time, the angular coverage of the lens increases so that your have a larger field of view. Try it: move your minus glasses away from and back towards your eyeballs, and the view compression effect will be apparent.

When the lenses sit on your eyeballs, view compression is absent and the field of view is not clipped. This is the case when you wear contact lenses. For glasses you can get these benefits to some degree by choosing a frame with really small diameter lenses and adjusting the nose pads and ear hooks to position the lenses closer to your eyeballs than you would be able to with larger diameter frames: these won't fit between your eyebrow ridge and cheek bones. The practical limit on how deep you can place small-diameter lenses is reached when your eye lashes brush against the lenses.
