    We Specialize In

    Imagine being able to see the world without the hassle of glasses or contacts. It’s possible with Corneal Reshaping Therapy (CRT) from Lumen Optometric. CRT is an FDA-approved, non-surgical treatment that corrects your vision by gently reshaping your eyes while you sleep.

    Scleral lenses can make an incredible impact on your vision. For those with vision-distorting conditions such as keratoconus, pellucid marginal degeneration, or post-LASIK complications, scleral lenses can change your life.

    As we work more and more on digital devices, things like headaches, eye strain, tired eyes, and stiff neck/shoulders are becoming an accepted part of our lives. We want you to know that experiencing these symptoms is NOT normal. If you suffer from any of the above symptoms, we can help.

    Testimonials
    Dr. To has been one of the best doctors I've seen for my condition hands down. Due to my eye condition I have to get scleral lenses. It was the easiest and most professional staff to work with. I am really happy with the turn out and HIGHLY recommend them if you need scleral lenses.
    Virginia L.
    We have been going to Lumen for a couple of years now. Everyone is fantastic!!! My husband and I both have the Neurolens glasses and our headaches have decreased by at least 90%. Dr. Eric To is great, he takes the time to explain everything during the examination and answers all of your questions
    K.G.
    Our experience has always been a positive one. I didn't think my insurance covered vision but the front desk staff encouraged me to at least let them check. They saved me hundreds of dollars! Great addition to Sierra Madre!
    Drew
    The staff here is the best staff I have ever interacted with in the medical industry, hands down. They are extremely knowledgeable, professional, excellent at communicating, and super prompt. They are also so quick to reply via email and they even text. That is seriously so impressive.
    Tramanh N.
    Dr. Eric To covered many aspects of the eye that I had never experienced. His office uses several eye equipment that looks into different parts of the eye that resulted in my rx glasses being made the best rx glasses I've ever had - and I've been seeing eye doctors for nearly two decades.
    Noemi S.
    Dr. To saved my quality of life- no exaggeration. I thought I was losing my vision, and I had so much pain. He figured out what two other doctors could not. I could not be more thankful he helped me. Thank you, thank you. From, Your Former Neurolens Skeptic
    Leslie G.
    Clean and efficient office with friendly staff. It was my first time getting glasses and Dr. To was friendly and very helpful in explaining my options.
    Jordan R
    My favorite place to go get my eyes checked! I’ve been going to this location for 2 years and each time I’m happy when I leave. I’ve also had to send a few questions through out the years and they are always fast with a response. Definitely recommend!
    Haley L
    You will find nothing but the BEST at Lumen! Thank you for taking the time to help Malia find the perfect glasses and for answering all of her questions!
    Ashley W
    I'm always leary of going to eye doctors. But I have to say that without a doubt coming here was amazing! The eye exam was easy and thorough and the glasses I got are a revelation. I am a customer for life.
