Oohh! OOOh! I know! I know!
They work the same as normal only... the other way around!!!
No-one knows what that means, though, and that includes Peacegirl. |
What does needing spectacles have to do with the claim of efferent vision. If the eyeball is not curved perfectly, there will be refractive problems, but this has to do with with the mechanics of the eye (the window of the brain) rather than with the brain itself. It would be like looking through a window that has a crack in it, or that has some other defect.
Refractive errors are optical imperfections that prevent the eye from properly focusing light, causing blurred vision. The primary refractive errors are nearsightedness, farsightedness and astigmatism.
