摘要: Myopes have a reduced accommodative response to negative lenses compared with nonmyopes. Mathematical models predict that the is due decrease in sensitivity blur myopes. We examined effect of induced by positive and defocusing on visual acuity 12 myopes nonmyopes during cycloplegia for up +/-3.00 D defocus 0.25 steps. Although showed symmetrical reduction lenses, myopic group less loss lenses. The magnitude was lower No significant difference found between Residual accommodation (after cycloplegia) about 0.20 both too small explain relatively good through minus group. known occur may be lens has their acuity.
