A new perspective on Phantom Eye Syndrome
Researchers from the University of Liverpool have found that approximately half of patients who have an eye removed because of a form of eye cancer experience ‘phantom eye syndrome.
A world without color — researchers find gene mutation that strips color, reduces vision
People with achromatopsia, an inherited eye disorder, see the world literally in black and white. Worse yet, their extreme sensitivity to light makes them nearly blind in bright sunlight.

Researchers conducting a comprehensive proteomics analysis of human aqueous humor samples identified 763 proteins – including 386 proteins detected for the first time – in this clear fluid that helps…
Alterations to the eye microbiome of contact lens wearers may increase infections
A study comparing the bacteria found in the eyes of people who use contact lenses with that of non-lens wearers finds the two groups have different microbiome compositions.

Smart micro chips may optimise human vision
To date, chip-based retinal implants have only permitted a rudimentary restoration of vision. However, modifying the electrical signals emitted by the implants could change that.
