Abstract
|
|
|
Purpose: This study was aimed at investigating whether changes in light transmittance depend on the pantoscopic angle and distance between the optic point in lenses with different indices, refractive powers, and coatings.
Methods: Lenses with different refractive indices, refractive powers, and coatings were enrolled, and light transmittance was measured using a spectrophotometer.
Results: Light transmittance of the lenses decreased by 1.20% when pantoscopic tilts were increased. Light transmittance correlated most strongly with a lens with a refractive index of 1.56. Light transmittance of the lenses decreased by 5.59% when the distance from the optic point was increased. The amount of decrease in light transmittance was the largest in the ?3.00 D lens. As the distance from the optic point increased, the decrease in light transmittance correlated more strongly in all lenses.
Conclusions: The results of this study confirmed that the decrease in light transmittance was related to the distance from the optic point rather than the pantoscopic tilt.
