Hamilton has a dig at a 'blind' Vettel fan

Cape Town - Lewis Hamilton hit back at a Sebastian Vettel fan, who suggested that the German was the more accomplished of the two drivers, saying he should perhaps stop by "Specsavers."

Following his victory at the Singapore Grand Prix, Hamilton engaged fans in an Instagram live video.

When it was suggested to him by 'Kevin' that Vettel was the more accomplished of the two F1 drivers, the Brit made his thoughts clear. 

"One day you will see that Vettel is not the best," Hamilton, who on Sunday claimed his 60th grand prix win, said. 

"If you haven't, then maybe you need to go to Specsavers."
