MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202641100243 A) filed by Forus Health Pvt Ltd. on August 19, 2026, for System And Method For Initial Estimation Of Refractive Errors In Vision.
Inventors include Pal, Sourav; Srinivasan, Venkatakrishnan; and Sidiq, Kousar.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: Disclosed herein is method (600) for making initial estimate of refractive errors in vision of subject. Method (600) includes displaying (602), predefined radial line pattern (132) on display device (130). Obtaining (604), based on first input from input device (120), first focal length value (S1) of the tuneable focus lens (112) of digital phoropter (110) corresponding to clearest first angular line set of the predefined radial line pattern (132). Obtaining (606), based on second input from the input device (120), first angular value corresponding to orientation of first angular line set. Obtaining (608), based on third input from the input device (120), second focal length value (S2) of the tuneable focus lens (112) corresponding to clearest second angular line set orthogonal to first angular line set. Making (610) initial estimate of the refractive errors of the subject based on first focal length value (S1) and second focal length value (S2).
