ZEISS has entered into a license agreement with CREAL to develop a digitized vision care platform using CREAL's light field display technology. The partnership aims to revolutionize vision diagnostic and treatment procedures by introducing devices that enable digital examination of eye conditions and virtual simulation of ophthalmic lenses and contact lenses. This collaboration seeks to bring century-old vision test procedures into the 21st century, providing fast, cost-effective, and user-friendly diagnostic procedures. The integration of CREAL's technology into vision test devices will allow for precise digital diagnosis of eye defects and the replication of any physical or theoretical lens. The ultimate goal is to enhance the prescription eyewear customer buying experience and accelerate the development of vision-health and vision enhancement enterprise. [Extracted from the article]
