I work for Infosys and I have taken vision plan from Birla sun life company 3 years back .I have made lot of home work while choosing the plan.
I almost took 2 months to compare with all other insurance companies, later I decided to choose BIRLA for the product features. I feel Birla gives higher bonus rate and most of the benefits are guaranteed.
Even the recent year bonus rate is very high. Very tight option I have taken and am happy about the service provided.
