MAKING OF PROGRESSIVE SPECTACLE LENS CUSTOMIZED BASED ON BLUR PERCEPTION |
摘要 |
The invention relates to the making of a progressive spectacle lens for customizing the lens based on the blur perception by a future lens wearer. Accordingly, a blur threshold value is determined for the wearer according to a blur perception criterion that varies based on an optical-power addition value prescribed for the wearer. The blur threshold value is associated with a reference sight direction for the lens provided to the wearer. |
