I have already replaced my lens within one year of purchase from LENSKART. But now it was useless again due to patches formed to disturb clear view. Now the frame(VINCENT CASE Gun metal) also broken. Very bad products from lenskart both have life period of Less than 2 years only including one replaced lens. very very bad products. Don’t go with Vincent case frames and anti reflection coated lens. because the coating formed patches in Lens and disturb clear view. Very cheap and lowest quality products from LENSKART.
