Where and how does someone buy prism lenses?

Published on

Prism lenses are specialized lenses, and while they can be prescribed by any optometrist using any lab, the key to effective treatment with prism lenses is how it's being prescribed. 

At our neuro optometric eye care clinic in Bellflower, we specialize in prescribing advanced prism designs for patients who have experienced a head injury, stroke, or have other conditions that will benefit from these specialty lenses. Under the leadership of Dr. Eric Ikeda, FCOVD, DPNAP, a recipient of the Skeffington Prize and former president of Neuro-Optometric Rehabilitation Association, we are referred patients from many of the leading rehabilitation centers in the Los Angeles area.  Patients with functional vision issues following a head injury or stroke visit our clinic from all over California, and we are proud to be a leading provider of neuro optometric rehabilitation services for patients from Bellflower, Long Beach, Lakewood, and Los Angeles.

Dr. Ikeda was recognized as “Physician of the Year” by the Rehabilitation Nurses Society in 2012 and currently serves as program director for the Neuro Optometry Clinic at Casa Colina Centers for Rehabilitation in Pomona. He provides clinical staff services at Rancho Los Amigos National Rehabilitation Center (Downey). Dr. Ikeda was appointed to the American Optometric Association Vision Rehabilitation Committee and to the TBI (Traumatic Brain Injury) Task Force. 

When you are prescribed prism lenses at Amplify EyeCare of Greater Long Beach, you are working with a team that has years of leadership experience in the field of prism lenses for even the most complicated cases. 

How long does it take to see a difference after wearing prism lenses?

There are cases where Dr. Ikeda sees patients who have poorly organized spatial concepts, they tend to hug the wall, when they're walking, they have a shifting posture, and ambulation, they feel very unsteady. And so when we present them, we do a prism test, we try different prisms again, we determine what direction we're going to place the base of the prism. And oftentimes it immediately has a very profound effect. Prescribing the prism is the first step of helping the patient, the second step is to make sure the patient is able  to integrate the change in space, because they have adapted to their visual deficits by adapting their posture, which now needs to be corrected. And so our job is to get them working with our neuro optometric vision therapist while using the prism. So it's done safely and the changes get integrated into the motor system. Once the patient works with the therapist to adapt, they start to improve or work on their spatial map, we are creating a neurological change in how they perceive the space around them. 

Who can benefit from prism lenses? 

Prism lenses are prescribed for patients with many different visual conditions or who have symptoms that include: 

  • Stroke
  • Migraine
  • Head injury or traumatic brain injuries (TBI)
  • Convergence insufficiency
  • Strabismus (crossed eyes)
  • Tumor
  • Diabetes mellitus
  • Multiple sclerosis
  • Binocular Visual Dysfunction (BVD)
  • Myasthenia gravis
  • Graves’ disease

Schedule a neuro optometric rehabilitation vision evaluation at our Los Angeles Neuro Optometric Rehabilitation Center

Our eye doctors see patients from all over the Los Angeles area and Southern California who have vision issues following a TBI (traumatic brain injury), stroke, or conditions such as MS (multiple sclerosis). We have tremendous success helping our patients enjoy profound improvements to their visual function and quality of life using a combination of prism lenses and in-office guided therapy that helps them integrate their prism lenses. As a world class neuro optometric center, we are referred patients from our colleagues in optometry and ophthalmology, as well as from other health care professionals such as occupational therapists, physical therapists, and neurologists. We work extensively with workers compensation and litigation, and are known as the go-to clinic for the hardest to care for cases. 

If you, a loved one, or someone you know is experiencing difficulties following a head injury or other conditions that may benefit from a prism lens, call our office at (562) 925-6591 to schedule a neuro optometric evaluation. 


I haven't actually used the optometrist side, so my review is limited to the vision therapy offered.  This office was recommended by my occupational therapist for the treatment of my double vision following a stroke.

Love this location. I had a brain injury accident from day one one. All the team make you feel you still important and hope in the horizon after when the medical system fell you miserably. Dr. Ikeda very professional and very understanding about your issue. Two tombs up.

My husband and I were immediately impressed with Dr Ikeda. I was hit by a car while cycling which caused broken bones and three brain injuries. The brain injuries caused double vision. Dr. Ikeda examined my eyes and got me started on vision therapy with his occupational therapist who specializes in vision therapy.  She (Chris) is absolutely great.  I am impressed with the array of tools used to help recover my binocular vision.  I am doing things I never thought were possible (balance boards etc).  Chris pushes me and keeps me motivated. I really enjoy my sessions with her.  The office staff is always friendly and they have a wonderful appointment reminder tool that makes it easy to keep my calendar up to date. I am happy the rehab center at Little Co. of Mary recommended them!!

The Vision Therapy is handled in a separate office through a different door from the shared waiting room. Chris, the vision therapist, has a wide and varied assortment of tools, equipment and resources to best evaluate and treat most vision issues. After just a few visits, my double vision became easier to control, using exercises developed during the therapy process. It was time well-spent.

I have been coming here since I can remember. I love it here. The staff is so amazing and nice. They explain everything they gonna do and never make you feel rushed. Dr. Ikeda has always been my doctor and I would never want another one. He is the doctor for my whole family and is always asking how everyone is doing. I am also so crazy about picking out my frames and have to try so many and each person who helps me take the time and lets me try them all on. I would never want to go anywhere else! I definitely would recommend this office to anyone looking for a great eye doctor.

This is not for the eye exam but for the frames selection portion. I brought my prescription from Kaiser here with my VSP insurance. The reception staff was very polite and professional.  Manny helped me to pick out frames and explain my coverage.  Very helpful and patient not like the individual at the other place I rated here on Yelp.  I was running late and he still helped me and was not bothered at all.  I am so glad I came here ..........very pleased.

Very professional staff and pleasant.
