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.

Our patient's health will always be of the utmost importance. With that in mind, we have been using recommendations for opening from the CDC, the American Optometric Association, and our government. Many of these changes will be very different than we are used to.

An appointment will be needed to enter the office and all patients will be screened prior to entering the office (temperature checks, face mask required, COVID questionnaire).  If you are an adult with medical conditions that exempt you from wearing a mask, a doctor's note is required to enter our practice. If these are not met upon screening we will gladly reschedule to a later date.  We will also take appointments for car side glasses pickups and adjustments. We appreciate your patience with these new guidelines.  It truly is a different world and way of doing things but they are meant to keep our patients, staff, and community healthy during the pandemic.  We are looking forward to seeing you all again soon! If you have any questions or concerns please give our office a call.
