What is it about?

The majority of lenses implanted after cataract surgery have traditionally been clear, and designed only to block UV light. There are, however, blue-light-blocking lenses on the market that are intended to protect against blue-light damage to the retina.

Why is it important?

Several studies have proposed that blue-blocking lenses do not affect visual perception; however, we present data here that luminance contrast perception when based on colour stimuli is changed when blue light is blocked.


I enjoyed working on this collaboration, specifically because as a researcher I learned a lot about surgical interventions and about the need for researchers and clinicians to collaborate, each highlighting their specific skills.
