Remote Optical Prescription System for Accurate Online Eyeglass Purchase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for purchasing eyeglasses and contact lenses online lack the capability to determine accurate lens specifications and refractive errors, requiring customers to visit opticians for prescription lenses, and do not enable direct home delivery of completed pairs.
Innovation Solution
A system that uses digital imaging and advanced ophthalmic instruments to determine visual acuities and refractive errors, allowing customers to obtain optical prescriptions through a network, with remote eye doctor interpretation and auto-refractometers, auto-lensometers, and auto-phoropters for precise lens specifications, enabling direct purchase and home delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If customers purchase eyeglasses online using existing systems, then convenience is improved, but the ability to obtain accurate lens specifications and prescriptions deteriorates
Solution Approach 1:
The patent introduces a remote practitioner as an intermediary who receives vision screening data from automated instruments, interprets the results, and provides authorized prescriptions. This mediator bridges the gap between automated online screening and accurate medical diagnosis, enabling convenient online purchase while maintaining prescription accuracy through professional oversight.
2Measurement precision
If customers visit opticians for in-person examinations, then measurement precision of prescriptions is improved, but loss of time and convenience deteriorates
Solution Approach 1:
The system performs preliminary vision screening using automated instruments (auto-refractometer, auto-lensometer, digital imager) before remote practitioner interpretation. This preliminary automated assessment captures essential vision data, allowing the remote practitioner to efficiently review and authorize prescriptions without requiring full in-person examinations, thereby reducing time loss while maintaining accuracy.
3Ease of operation
If existing online systems are used for eyeglass purchase, then ease of operation is improved, but reliability of obtaining complete prescription eyeglasses deteriorates
Solution Approach 1:
The patent merges automated vision screening instruments with remote practitioner interpretation and electronic prescription authorization in a single integrated online system. This combination unifies the convenience of online操作 with the reliability of professional medical oversight, enabling customers to obtain complete prescription eyeglasses through a unified remote process rather than separate online and in-person steps.

AI summary
Systems and methods are provided for obtaining sight screenings, optical prescriptions and fittings for eyeglasses and contact lenses. A system can be self-operated through a voice-activated response system that enables an individual to determine one's own refraction, or can be operated with the assistance of a technician. A plurality of customer diagnostic locations can include digital equipment and optical instruments to conduct the sight screening. The data generated at these locations can be transferred to a remotely located eye doctor who interacts with a customer via a live audio-video connection to assist with interpreting the data, diagnosing the customer and operating the instruments at the locations. The eye doctor diagnoses, consults and authorizes the prescriptions for the customer. The customer's data can be sent to a lens laboratory to enable the fabrication, purchasing, and delivery of eyeglasses or contact lenses.
