WebbVA while wearing both types of pinhole glasses improved due to the pinhole effect. A smaller aperture than the pupil can reduce the blur circle (3, 9) and block aberrant incident rays from the peripheral cornea and lens (10, 11, 12). Hence, pinhole glasses improved distant and near VA. WebbAlso, a similar effect happens with points of light in the focal plane, but not at the focal point -- emitted light from these areas is blocked by the pinhole screen. So a confocal microscope has slightly better resolution horizontally, as well as vertically.
