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).

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.

Due to the rapidly evolving situation with the COVID-19 pandemic, and to continue our commitment to the safety of our patients and community, Vintage Optical will be postponing all routine eye care visits. We will continue to be available for all essential and emergency care during this time.

 

While our office will be closed for non-medical care, there are a few ways we can help with other eye care needs at this time:

If you are scheduled for a non-medically necessary visit in the upcoming weeks, we will call you to postpone your exam to a later date. We ask for your understanding and appreciate your help in reducing the spread of infection in our community.

 

In light of this need to limit community exposure, Vintage Optical will be working with an accelerated telemedicine program to provide certain urgent care needs to our patients from their home.

 

If you have an urgent eye care need, please do NOT go directly to the emergency room, but call our office at 309-263-8611. If appropriate, we will schedule a virtual visit with one of our doctors to address your needs and do our part in protecting our community. If your eye care needs would be better addressed in person, we will continue to be available for in-office emergency care throughout this crisis. As always, if you have a life-threatening emergency, please call 911. We appreciate your help in reducing the burden on emergency departments and urgent care centers during this time.

 

We have wonderful patients and love seeing you in our office, and while this is yet another inconvenience during an already stressful time, we're doing everything we can to limit the effects of this pandemic on our community.
