APPARATUS AND METHOD FOR MEASURING VISUAL ACUITY BY USING FOCUS-TUNABLE LENS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17874958 titled 'APPARATUS AND METHOD FOR MEASURING VISUAL ACUITY BY USING FOCUS-TUNABLE LENS
Simplified Explanation
The patent application describes an apparatus and method for measuring visual acuity using a focus-tunable lens. The apparatus includes a display engine, an image combiner, a focus-tunable lens, an input device, and a processor. The focus-tunable lens can assign different optical powers to different lens regions on its surface. The display engine displays a visual acuity measuring image through the image combiner. The input device receives user input related to the image. The processor controls the focus-tunable lens based on the user's input and determines the user's visual acuity based on the specified optical power.
- The apparatus uses a focus-tunable lens to measure visual acuity.
- The lens has different optical powers assigned to different regions on its surface.
- A display engine and image combiner are used to present a visual acuity measuring image to the user.
- The user provides input related to the image using an input device.
- The processor controls the focus-tunable lens based on the user's input.
- The visual acuity of the user is determined based on the specified optical power.
Potential Applications
- Optometry and ophthalmology clinics for measuring visual acuity in patients.
- Vision testing in schools and workplaces.
- Research studies on visual acuity and its variations.
Problems Solved
- Provides a more efficient and accurate method for measuring visual acuity.
- Allows for customization of optical power based on user input.
- Reduces the need for multiple lenses or manual adjustments during visual acuity testing.
Benefits
- Faster and more precise measurement of visual acuity.
- Improved user experience with customizable optical power.
- Simplifies the process of visual acuity testing for both users and practitioners.
Original Abstract Submitted
Provided are an apparatus and method for measuring a visual acuity (VA) by using a focus-tunable lens. The apparatus includes a display engine, an image combiner, a focus-tunable lens provided on a path of the light guided by the image combiner, an input device, and a processor configured to control the focus-tunable lens to assign different first and second optical powers to first and second lens regions, respectively, on a lens surface of the focus-tunable lens, control the display engine to display a VA measuring image through first and second output regions of the image combiner, control the input device to receive a user's input with respect to the VA measuring image, specify one optical power of the first and second optical powers based on the user's input, and determine a VA of a user based on the specified optical power.
