Lenskart — Air bubbles on my and my mom's spectacle glass lenses

Address:

Karve Rd, pune

It has been 2-3 years since I bought a pair of glasses for me and my mom worth 12k each. I have noticed that in recent times the glass has started developing air Bubbles on the surface maybe because of green coating or whatever. Had also visited a lenskart showroom where they told that it cannot be fixed. Why would you charge such a high amount of it's the same quality as any other brand
