Beware of Vision Express. They sell poor quality and cheap defective lenses at high prices made by incompetent and inexperienced staff. Do not use their lenses as it will spoil your eyes.
The frames they sell are very cheap ones which break frequently and they make good business in selling you new frames.
The staff is typical zhopad patti types who does not understand anything and they behave like parrots and babble whatever taught by their seniors, who are bigger parrots.
As it is a venture by Reliance, we all know what to expect from a cheater.
Search on google and you will come across thousands of bad experiences written by people who suffered due to defective spectacles.
Such companies should be banned in India as they are posing health hazards.
