Filters for Low Vision

Sometimes, low vision patients experience vision difficulty in certain lighting conditions. Fortunately, specialized filters exist which can help maintain comfort in all environments.

What are Filters for Low Vision?

Some low vision patients have difficulty seeing in certain lighting conditions. There is a range of filter types that can help these patients see better in those conditions, and the type and intensity of the filter will vary based on a patient’s individual condition.

Filters may be recommended for patients that have difficulty with:

  • Bright lights 
  • Night driving
  • Outdoors in bright sunlight 
  • While on the computer or phone

There are two categories of filters for low vision:

Polarizing filters: These filters reduce glare, and also heighten the perception of color and relief.

Color Filters: Color filters improve visual function by optimizing contrast perception .

How do Filters Work?

Filters for low vision patients function in a similar manner to sunglasses, in that they affect the amount of and type of light that enters the eyes. In addition to increasing visibility and comfort, they can also provide protection for the eyes.

For color filters, the different tints change the nature of the light entering the eyes to provide additional clarity and contrast in different situations (for some, filters are needed while outdoors while sunny or while cloudy; for others, while indoors.

Polarizing filters filter out glare to increase comfort and to increase visibility outdoors.

How Are Filters Prescribed?

Filters for low vision patients are either prescribed by a low vision doctor, following a low vision eye exam, which tests for color contrast deficits.  After the exam the doctor or low vision therapist will walk you through the options of filters that are available and match the doctor's recommendations.

How Are Filters Prescribed?

There are a few types of lenses which utilize filters.

Fitovers: These are lenses that can go over regular glasses lenses, and are ideal for patients who wear prescription glasses but do not need a medical tint at all times. Additionally, patients who want lenses for low vision as quickly as possible, and those who wear different types of glasses and want an option that works with all of their frames.

Fitover lenses are also often more affordable

Clip-on: Clip-on lenses are also easily removable, but are more fitted for a specific pair of frames, making it hard to use with multiple pairs of glasses.

Plano glasses: Plano glasses are a lightweight, convenient option for patients who do not already wear prescription glasses.

Built In on lens filters: Filters can be ordered for your prescription lens. Another example of filters are escoop glasses that include slight magnification and prisms.

Filter lenses, which can be fit over the glasses you already wear, can be extremely helpful for low vision patients who are having difficulty seeing in certain conditions. While not all filters need to be prescribed, filter purchases should be made based on the advice of a low vision doctor. If you think filters can help you, you can contact Amplify EyeCare of Greater Long Beach at (562) 925-6591 to schedule an appointment for a low vision eye exam.



  • 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.
