While Khan is mostly known for making bulk sunglasses, the brand has deviated and started making reading glasses. Designed for modern men, these rectangle-style reading glasses are an ode to those glasses from the 1950s, but feature a facelift with lightweight plastic and the telltale Khan logo on the temple. Available in classic black or tortoise brown, these reading glasses are an excellent investment for today's retailers who are looking for profitable items. In fact, most people easily lose or misplace reading glasses, which is why they are profitable selling accessories in airports, bookstores, pharmacies, etc.
