Accommodative response to ocular surface pain

Clinical and Experimental Optometry, 2021
The discovery of an accommodative response to ocular surface stimulation could inform clinicians and patients that optical effects may occur due to ocular discomfort and perhaps an assessment of the accommodative system after carrying out interventions impacting the ocular surface, may be warranted.There have been no previous reports evaluating the ...

Spectral bandwidth and ocular accommodation

Journal of the Optical Society of America A, 1995
Previous studies have suggested that targets illuminated by monochromatic (narrow-band) light are less effective in stimulating the eye to change its focus than are black-white (broadband) targets. The present study investigates the influence of target spectral bandwidth on the dynamic accommodation response in eight subjects. The fixation target was a

Ocular Aberrations and Accommodation

Ophthalmic and Visual Optics, 1992
It has been generally considered that on the visual axis in monochromatic light, the eye is limited only by diffraction effects for pupil diameters up to 2mm1 and thereafter is predominantly affected by spherical aberration. Most eyes are considered to suffer from positive spherical aberration when unaccommodated, which tends to negative spherical ...

Changes of ocular aberration with accommodation

American Journal of Ophthalmology, 2002
To study the effect of accommodation on ocular aberrations.Observational case series.The ocular aberrations in 33 eyes of 33 young adults were measured with a Hartmann-Shack wavefront aberrometer before and during 3 diopters of accommodation.The root mean square values of wavefront error did not change for a 4-mm and a 6-mm zone; however, spherical ...
