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.

In response to the recent announcement of Governor Abbott’s Executive Order on the mask mandates, we would like to reinforce the importance of mask-wearing in our office as recommended by the CDC and the State and Federal Optometric organizations. All staff members, patients and guests will be required to wear a mask in our office even if vaccinated. Although we have been encouraged by the recent declining COVID-19 cases and hospitalizations as well as increasing vaccinations, it is essential to continue our safety efforts to help stop the spread and reduce transmission as new COVID-19 variants spread across our communities.

Our top priority is the safety of our team members, patients and their families. Thus, we will continue to enforce all of our existing COVID-19 prevention protocols by diligently disinfecting all surfaces, practicing hand hygiene, socially distancing and wearing a mask in the office. We truly appreciate your support and understanding as we protect our employees, patients and communities.
