Mumbai: Megastar Amitabh Bachchan is fascinated with the hi-tech devices and treatments available for the eye, but he likes his uber cool frames the best because they have 'more character'.

The 69-year-old likes experimenting with different eyewear - on screen as well as off screen.

He tweeted: “Went for routine eye check up, learnt they have device to surgically put a multifocus lens inside your eye, so you never need glasses. Very rapid technical advances in the field or opthalmic devices... every three months something new makes other equipment obsolete!”
