Do yellow-tinted intra-ocular lenses block blue light to a point where patients notice this effect?

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.
