Our Areas of Focus

Myopia Management

As a parent, you have one chance to slow/stop myopia and that’s when your child’s prescription is low. When their eyes are protected from myopic progression, they maintain a lower prescription and their eyes remain healthier as they grow into adulthood.

Scleral Lenses

Scleral lenses can greatly improve your eyesight. If you have complex vision problems or conditions such as keratoconus or severe astigmatism, these lenses can help you to see more clearly than with glasses or contacts.

Neurolenses

Since we spend so much time on our digital devices, problems like headaches, tired eyes, and stiff necks are becoming common. But it’s important to know that feeling this way is NOT normal. If you’re coping with these issues, Neurolenses can provide significant relief.

Testimonials

https://lumenoptometric.com/wp-content/uploads/2021/08/floating_image_03.png

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.

I was under the care of Dr. Valerie Hoshizaki for the last three years, I do not have enough gratitude for all her attention and patience, regarding my keratoconus, she and her team are very patient and careful, they know what they are doing and how exhausting and stressful, can be suffering from the keratoconos disease, if you are tired of going with doctors who do not have the patience for this progressive disease I recommend 100% to Dr. Valerie and her team.

Laura R.

Beyond impressed by the helpfulness and hospitality-forward employees (which is not a characteristic I would expect to use to describe an eye doctor office). Dr. He was so nice, warm, thorough, clear, concise, proved to have a really strong memory/actually listens to patients and processes what patients said + applies it real time to individual treatment plans. The equipment was really modern, gentle on my eyes, and I'm confidently saying best eye exam for quality and staffing ever.

Alicia R.

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.

All the staff was really friendly and helpful. There were some difficulties with my insurance and ordering my contacts but the staff was really helpful and able to address it. My doctor, Dr. He, was wonderful! I have never had an eye doctor explain so much to me. She was very thorough, patient, and gave me so much time. She was concerned I may have a condition with my eyes and she took a lot of time to fully explain the condition and next steps. She provided excellent care.

Amanda C.

Dr. Hoshizaki is the best! She is knowledgable and kind, very thorough and caring. You can't beat kindness and caring in the healthcare industry! Highly recommed!!

Lucy Y.

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.

My visit to Lumen Optometric exceeded all expectations. From start to finish, I was impressed by the thoroughness of their explanations regarding my eyes, prescription, available options, and costs. The staff demonstrated exceptional professionalism coupled with genuine friendliness and helpfulness throughout the entire process. I am pleased to say that Lumen Optometric has earned my trust and loyalty. Without hesitation, I will be returning to them for all my optometric needs.

Kim A.

As someone who has worn glasses or contacts their whole life, and visited my share of optometrist, Dr. To and his team are strides above the rest. This place is top notch. The team and doctor are friendly and personable. Top tier technology in the office, I felt like I took a mini crash course in optometry myself while being explained the condition of my vision and what is possible. You don't often find yourself telling your buddies about how cool your trip to the optometrist was, but this is that type of place.

Blake S.

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.
