I went to Titan eye for my spectacle, it was progressive lenses, cost close to 23000, including frame , they recommended Titan eye lens, while the options are available with essilor and others brands,
I also having trust in TATA brand and opted for TITAN eye lenses, Cost around 15000 rs.
However the protective coating of the lenses came out within a year causing blurred vision, I should have opted for the branded lens like essilor or Zesis.It is a waste of money and discomfort believing in Titan eye lens.
