## What is Sensitivity Tests?

The first vision sensitivity measurements that can help eye care professionals to measure the sensitivity score of their patients, which will be used as a unique personalization parameter for Nikon's latest lenses and will provide a unique design according to each visual preference. The tests work by showing the participant images with different levels of bluriness and asking him to choose the image where the letters start to be defined.
