AI Technical Summary
Existing refraction measurement technologies are inadequate for low-vision patients due to their impaired central vision, making it difficult for them to perform subjective refraction measurements, and they often have uncorrected refractive errors that further reduce their visual acuity.
A telescopic ocular refraction test apparatus and method that uses a focusable telescope with adjustable magnification to enable low-vision patients to clearly view vision testing images, allowing for accurate determination of vision correction parameters such as sphere power, cylinder power, and cylinder axis.
Enables low-vision patients to achieve improved visual acuity by providing accurate lens prescriptions, potentially improving uncorrected visual acuity from 20/1000 to 20/200, facilitating precise refractive corrections for hyperopia, myopia, and astigmatism.
