Postblink changes in the ocular modulation transfer function measured by a double-pass method.

摘要: PURPOSE. To examine the temporal changes in modulation transfer function (MTF) of eye after a blink. METHODS. The distance MTF 5-mm pupil was derived from double-pass retinal images 20 healthy young subjects at various intervals blink (1 second up to 15 seconds). Such measurements include effects wavefront aberration, scattered light, and errors focus are thus more relevant real life than estimates based on alone. RESULTS. Optimal by variety criteria found some 6 seconds CONCLUSIONS. Inclusion stray light does not affect finding that optimal image quality occurs time It appear loss optical is trigger normal blinking.
