High Index and Aspheric Lenses

What are High Index Lenses?

A high index lens is a lens that has a higher “index” of refraction. This means it has a greater ability to bend light rays to provide clear vision for people with stronger prescription glasses. But that’s the technical terminology. What do high index lenses mean for eyeglass wearers?

Thinner, lighter, and more visually appealing, that’s what! High index lenses are manufactured to be thinner at the edges of the lens and lighter in weight overall.

High index lenses are a good option for people who have strong prescriptions for myopia—commonly called “nearsightedness” due to a difficulty in focusing on far objects. A high-index lens can bend light rays more, while using less material in lenses created for both nearsighted and farsighted people (hyperopia).

No more soda bottle glasses

In times past, strong prescriptions meant thicker, heavier lenses, giving some a “glass bottle” appearance. But now, with high index glasses available in thinner, lightweight plastic (as well as slightly heavier glass), lens wearers with stronger prescriptions can get more attractive, yet equally effective, lens products. Because high-index lenses bend light more, anti-reflective (AR) treatment is often recommended as an add-on for optimum clarity of vision.

For better comfort, better vision and improved cosmetic appeal, people with strong prescriptions can’t beat high-index lenses.

To Our Patient Family,

Due to the COVID-19 pandemic and in the best interest of public health to help flatten the curve, our office will be following the CDC guidelines to postpone all routine eye care visits. We have made the decision to reduce our services to urgent/emergent eye care only until April 6th at which time we will re-evaluate.

What Does This Mean?

Although the physical office will be closed starting Saturday March 21st, there will be limited staff available to answer questions, place contact lens order, schedule urgent/emergent patients, etc. by phone at (512) 452-5735 from 9am – 1pm Monday through Friday.

Dr. Amin is still available for red eyes, sudden vision changes, injuries, and other urgent issues for both new and established patients. Please call us to schedule an appointment for urgent care.

If you have an eyeglasses or contact lens order ready for pickup, please call us to arrange a pickup time.

As always, we are here for you if you need us and if you have questions about your specific situation please feel free to call or email! God bless & stay safe!

Thank you for your understanding during this challenging time!
