When shopping for prescription glasses, lens material is just as important as the frame. Two of the most common options are 1.50 index lenses and 1.59 index lenses.

1. What is the difference between high-index lenses and regular lenses? Answer: High-index lenses are also known as ultra-thin lenses, generally with a refractive index above 1.70. Regular lenses feature a refractive index ranging from 1.49 to 1.53.

As a lens supplier, we don’t just want to tell you “what we can produce”; we’d also like to discuss how we can help you solve the challenges you face with your orders.

Many people start experiencing presbyopia (age-related farsightedness) after age 40. Seeing far is clear, but reading up close becomes a struggle.
