AI Technical Summary

Technical Problem

Current methods for measuring ocular refractive errors and determining the need for reading glasses are limited, as they primarily focus on the far point and do not account for interactive, subjective measurements of distance and object size, which can vary with age and visual task, leading to imperfect focus and visual quality issues.

Method used

A computer-implemented system that includes distance measurement circuitry, a user interface, and processing circuitry to interactively measure ocular refractive errors by adjusting the distance between a user's head and an electronic device, allowing users to choose the optimal interval of clear vision based on subjective preference, and calculating the necessary power for reading glasses.

Benefits of technology

Enables accurate, interactive measurement of refractive errors and power for reading glasses, improving visual quality by considering individual preferences and varying object sizes, thereby enhancing the precision of optical corrections.

Abstract

A system and method for interactively measuring ocular refractive errors, addition and power of reading glasses without the need of an optical component that would change optical vergence of a target. The system can measure the distance from a user's eyes to either or both border of interval of clear vision, for one orientation or two perpendicular orientations. The measurements together with the user's age can be used to estimate sphero-cylindrical refraction, addition and power of reading glasses. The system can use different sizes, directions and colors of targets which can change with said distance or user interaction.
