Systems and methods for evaluating and reducing negative dysphotopsia

A computer-implemented method for reducing the detectability of negative dysphotopsia (ND), comprising:

• constructing a respective NSC ray-tracing model of the eye with an ophthalmic lens for each of a plurality of different ophthalmic lens edge designs;
• modelling a light source and a detector, wherein the detector is configured to mimic a retina of the eye;
• for each of a plurality of pupil sizes, computing irradiance data using the light source, the respective NSC ray-tracing models, and the detector;
• evaluating ND by analyzing the respective irradiance data for each of the pupil sizes;
• and
• selecting one of the different ophthalmic lens edge designs to reduce ND.

A system, comprising:

• a processor;
• and
• a memory operably coupled to the processor, wherein the memory has computer-executable instructions stored thereon that, when executed by the processor, cause the system to:
• construct a non-sequential (NSC) ray-tracing model of an eye with an ophthalmic lens;
• model a light source and a detector, wherein the detector is configured to mimic a retina of the eye;
• for each of a plurality of pupil sizes, compute irradiance data using the light source, the NSC ray-tracing model, and the detector;
• and
• evaluate negative dysphotopsia (ND) by analyzing the respective irradiance data for each of the pupil sizes.

A non-transitory computer-readable medium having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to:

• model a light source and a detector, wherein the detector is configured to mimic a retina of the eye;
• for each of a plurality of pupil sizes, compute irradiance data using the light source, the NSC ray-tracing model, and the detector;
• and
• evaluate negative dysphotopsia (ND) by analyzing the respective irradiance data for each of the pupil sizes.
