Several studies are exploring the possibility that people who are already nearsighted, have
unusually high levels of aberration or show greater adaptive delays. The main aim of this …

The accommodation stimulated by convergence, CA/C, was measured under laboratory and
clinical conditions. There was a small nonlinearity to the CA/C ratios measured under …

The effect of a 14 minute near‐vision task on the response accommodative convergence/
accommodation (AC/A) ratio was investigated for three refractive groups (each comprising …

Purpose: Myopes have been shown to have abnormal accommodative characteristics. This
study investigated the characteristics of accommodation facility in myopic and emmetropic …

Previous investigators have observed that some subjects show large amounts of
accommodative lag. We hypothesized that less accurate accommodation might be …

Purpose: To clarify whether myopes show poor accommodative response and thus have a
larger accommodative lag under natural seeing conditions. Methods: Forty-three adults …

Results Fig. 1 shows the monocular accommodative response of an emmetropic eye. The
target moved from 0.5 to 5 D with a velocity of 0.25 Disec. The tonic accommodation …

Purpose: Prolonged near work is considered to be an environmental factor leading to the
development of late-onset myopia. Accommodation may be the specific mechanism …

The convergent accommodation/convergence (CA/C) ratio was measured in 30 subjects
comprising 10 late-onset myopes (LOM's), ie, myopia onset at 15 years of age or later, 10 …

Purpose: To compare accommodative convergence over accommodation (AC/A) ratio when
Myopic patient changes from Spectacles to Contact lenses. Methods: a prospective, cross …
