Developed by Microsoft Israel R&D Center Innovation Labs, Digital Lens is designed to work only with 32-bit Windows 7. At the same time, devs will need to have Windows Aero theme enabled. "Digital Lens currently supports following filters: Green-Red – Simulates green & red color blindness; Yellow-Blue - Simulates yellow & blue color blindness; Black-White – Simulates full color blindness; Blur - Simulates blurry vision; Dazzle – Simulates glare."
"Digital Lens was designed with the mission to simplify the process of finding problems that would make your UI less accessible to users with impaired vision. It provides UI designers and developers the tools to view the visual design as it would be seen by vision impaired users. By emulating common impaired vision conditions, Digital Lens users are able to identify issues in the UI and fix them before the product is released - with Digital Lens you are able to design a more accessible product," Microsoft stated.
