  • Abstract
  • Look Inside

The optical correction for ametropia was evalu-ated by measuring MTF of the human visual system corrected with contact lenses (standard-type hard, thin-type hard, soft) or spectacle lens. The MTFs were also measured in the condition of viewing through the optical center and some laterally eccentric parts of the correcting spectacle lens.

We found that the optical center of the spectacle lens was optically best for correction of the low and medium degrees of myopia. The MTFs me-asured while wearing contact lenses were almost equal to that obtained while viewing through 10 mm laterally eccentric part of the spectacle lens.
