Bionic eye that mimics how pupils respond to light may improve vision

Summary

This article by Jason Murugesu, writing for New Scientist, makes the following points:

• The recent creation of a bionic eye that mimics the widening and shrinking of the pupil may bring us a step closer to helping visually-impaired people.
• Light enters the eye via the pupil before travelling to the retina.
•  It then converts the light stimuli into nerve impulses sent to the brain (via the optic nerve) for processing.
• An artificial eye might help people who have double vision, light sensitivity, or difficulty focusing on nearby objects due to eye injuries, 
• The designer is now hoping to develop an artificial eye that perceives colour.
