refractive correction error
Hartmann test - Opis:
- In this work, we describe a new method for assessing the refractive correction error in power corrected ophthalmic lenses. The ideal power distribution map corresponding to the lens design to be measured is initially obtained. Then, using some known techniques, the real power distribution map of the lens under test is obtained. Finally, the difference between the two distributions is computed, obtaining a distribution map of the refractive correction error of the lens under analysis. In the paper, we describe the implementation of the proposed method using the Hartmann test to analyze a corrected power ophthalmic lens. The technique is analyzed, and its effects on measurement resolution discussed. This method can be useful to verify the designing errors in the lab or to verify manufacturing errors of ophthalmic lenses during mass production.
