Lenskart pr Titan eye plus?

Lens are scam of Lenskart

Neither. Go for local opticals. You can get good quality and price which will be cheaper than what you get at either of the stores.

And the big advantage - you don't have to convert to get a specs.

Lenskart has own labels only. Titan has both, own labels as well as branded ones. I personally prefer titan eye plus though have taken only branded frames and lenses from them.

Lenskart is not worth. They lack consistency in producing lens with accurate power. The last time I bought two pairs, one pair is somewhat fine while the other pair gives me blurred vision and headaches despite getting them exchanged.
