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.

Dear Valued Patients,

We would like to clarify to our patients that despite the province-wide lockdown starting Thursday, December 24, our office is still open.  Patients who have appointments already booked will still be seen as scheduled.

We will continue to operate in a way that is in alignment with provincial guidelines and is designed to keep you and our staff safe while still allowing us to deliver the high standard of eye care you are accustom to.

Our doctors have modified their schedules to increase physical distancing. As a result, fewer appointments are available, and we are having to assign these appointments to people with immediate and greatest needs.

We will also be:

• Using telehealth appointments, when appropriate, to deliver care from a distance.

• Time in our Frame Gallery will be scheduled for patients to try on and choose eyewear.

• All eyewear adjustments, repairs, and pick-ups will be scheduled.

• Our doors will be closed as we will not be accepting walk-ins at this time.

• Contact lenses will continue to be shipped directly to patients.

We look forward to servicing our amazing community with all their eye care needs and thank you for supporting us as we navigate these unprecedented times.
