Creal: A radically new way of subjective refraction
What does the future of subjective refraction look like? A Swiss start-up has an answer: refraction should be digital, offer almost unlimited display options, and also be independently manageable by the customer. Subjective refraction with the help of light field displays would therefore change the traditional way of doing the subjective refraction with a phoropter or trial frame set tremendously. Even a “refraction automate” in a shopping center is theoretically conceivable in the future.
