Development and Validation of a Disabling-Glare Mapping Device for Quantifying Dysphotopsia-Related Effects

Key Points

• The aim is to develop and validate a device that measures the size and shape of dysphotopsia produced by contact lenses.
• Utilized a mapping device to assess dysphotopsia related to two different optical designs of contact lenses.
• Measured repeatability to determine the consistency of the device's readings.
• Conducted comparisons between the dysphotopsia size and shape produced by the lenses.
• Successfully differentiated the optical designs based on dysphotopsia measurements.
• Achieved measurement repeatability within 8% error, indicating reliable results.
• Identified potential applications for the device in clinical practice, research, and lens development.
