Focusing on Low Vision

What is the difference between low vision and poor vision?

Beyond the borders of the vision community, the average person, likely is unfamiliar with the term ‘low vision’. It has become somewhat synonymous with the term ‘poor vision’. Even in the vision community, there are different definitions floating around that cause confusion, especially when it concerns referring a patient to a low vision specialist.

Two common definitions are:

  1. Low vision is vision that can’t be adequately corrected with glasses, contacts, medication, or surgery.
  2. Low vision is a term that refers to vision 20/70 or worse.

As we define it in our practice, low vision is a result of having an eye condition that prevents someone from doing the things that they want to do.

Common eye conditions that can cause low vision are:

  • macular degeneration
  • Stargardt disease
  • ocular albinism
  • retinitis pigmentosa
  • diabetic retinopathy
  • stroke-hemianopsia

Patients whose eyesight is affected might be having trouble performing tasks such as:

  • reading- books, newspapers, magazines, sheet music, labels on packaging including prescriptions
  • seeing faces
  • driving
  • playing cards
  • art projects
  • crafts
  • watching tv
  • seeing food on utensils

Although the damage sustained may be uncorrectable, our exclusive objective is to capture and maximize the utility of a person’s remaining vision. We can attain our objective through the prescription of highly specialized devices.

Our low vision practice focuses on identifying the best vision-enhancing device to allow the performance of specific tasks. Custom low vision glasses, such as bioptic telescopes, or microscope and prismatic reading glasses, are just a few examples of the hands-free aids at our disposal. Often, more than one device is prescribed to accomplish different tasks.

An example of a low vision patient is Jane.

Jane has macular degeneration. She found out that regular glasses won’t help and there isn’t a cure. She can’t read her Bible anymore or see the numbers well enough on her bills. It’s also hard to tell what is happening on tv. She feels frustrated and down. Jane has low vision. She is a perfect candidate for a low vision evaluation.

Here are some questions that may identify someone is a low vision candidate.

  1. Do you have a vision condition?
  2. Are there things that you can no longer do as a result?
  3. Does the inability to do these things frustrate you?

If the answer to all three of these questions is ‘Yes’, then the person would benefit from a low vision consultation. If the answer to any of these questions is ‘No’, they do not have low vision (they may have poor vision.)

Let’s compare a person with hearing loss to a low vision patient. For example, George has mild hearing loss (poor hearing). He mentions it to his primary care physician, but it is not severe enough to warrant a referral to an audiologist. Instead, George goes out and buys an over-the-counter amplification device so that he can hear his tv better.

Then there is Dennis. Dennis has more severe hearing loss than George. There are some tones that he can’t hear like the seatbelt alarm in his car, and he is concerned that his hearing could put him in physical danger. His primary care physician referred him to an audiologist. Dennis’ audiologist prescribed a specific hearing aid so that he could hear the missing tones and live confidently again.

Low vision specialists are the audiologists of the visual world. Our patients have moderate to severe vision loss and are frustrated with their inability to function in their everyday lives. We assess and prescribe custom, physical solutions for the things they want to do. Oftentimes, we see our patients for the initial assessment, at the dispensing, and thereafter, annually, or as needed to assess any vision loss that occurs over time.

Ever since William Feinbloom OD introduced low vision glasses in 1936 there has been hope and promise for people with low vision. Only recently has the standard of care evolved into the referral of low vision patients to a low vision specialist. What was once hope and promise is now a reality.

Our commitment has always been and continues to be that “There is life after vision loss”.

Dr. Jill Mogil is transforming the lives of many people living with Macular Degeneration through her low vision aids and glasses

Glasses are custom-made as per the patients’ requirements

Dr. Jill Mogil, low vision optometrist and Fellow of the International Academy of Low Vision Specialists (FIALVS), is the Clinical Director of Gateway Low Vision. Dr. Mogil specializes in prescribing high-powered, custom low vision glasses to patients with impaired vision due to glaucoma, diabetic retinopathy, or other eye diseases, particularly Macular Degeneration, a predominant cause of vision loss that affects millions of American adults ages 60+.

Speaking in detail about age-related macular degeneration (AMD), Dr. Mogil added, “The macula is the most sensitive part of the retina, the film in the back of the eye which turns light into vision. It is in the center and is responsible for clear, high-definition, central vision. Macular degeneration is an eye condition that occurs due to damage to the macula, thus, causing partial or complete loss of central vision.”

“My heart goes out to those who have lost the ability to do the normal activities that they love, like reading, watching TV, recognizing faces, and driving,” Dr. Mogil explained, “I’m honored to be a part of the team of doctors that include optometrists, ophthalmologists, and retina specialists who provide a holistic patient-first approach.” People lose hope of ever doing the things they love again, but a low vision practitioner can help by utilizing the custom glasses and other solutions available. Managing the effects of vision loss from conditions like macular degeneration is the critical task that Dr. Mogil attends to.

Through her education, training, and experience Dr. Mogil is uniquely qualified as a specialist in vision enhancement for low vision patients. Although low vision cannot be fully corrected, a wide array of low vision glasses and low vision instruments significantly improve vision, such as, custom bioptic or full diameter telescopic glasses, E-Scoop glasses, high powered prismatic reading glasses, etc.

As an IALVS Fellow, Dr. Mogil is a component of an international network of approximately 40 low vision optometrists located throughout North America. “We utilize our ever-improving arsenal of tools to enhance vision and help patients reclaim the ability to carry out tasks that are most important to them.”

Since referral of low vision patients to a low vision specialist is now recognized as the standard of care, many more low vision patients will benefit from Dr. Mogil’s expertise and association with IALVS. Patients will now be able to appreciate the phrase, “There is life after vision loss.” “Gateway Low Vision is committed to helping people improve their quality of life and giving them another chance to do what they love to do.” Vision Enhancement helps boost one’s confidence and morale, thereby reducing depression.

How Can Gateway Low Vision Help Patients with Glaucoma?


is one of the leading causes of blindness in older adults but can occur at any age. It is caused by damage to the optic nerve, often the result of pressure buildup in the eye. There are several forms of glaucoma; the most common is primary open-angle glaucoma, often called “the sneak thief of sight” because it has no symptoms until significant vision loss has occurred.

Glaucoma damage is permanent—it cannot be reversed. But medicine and surgery help to stop further damage. Early detection is crucial.

If glaucoma is caught early enough before the damage is too severe, usable vision could be significantly enhanced using high-powered low vision glasses. Making the most of the patient’s remaining vision is the goal.

Patients who are having difficulty reading, watching television, seeing loved ones, or even driving could greatly benefit from the services of a low vision specialist. Dr. Jill M. Mogil, a low vision optometrist and a Fellow of the International Academy of Low Vision Specialists (FIALVS), is the Clinical Director of Gateway Low Vision. Dr. Mogil is uniquely qualified to prescribe special low vision glasses and other devices. She will perform an extensive vision examination to determine which low vision glasses, such as bioptic and full diameter telescopes, microscope reading glasses, or other high-powered devices, a patient will benefit from.

An initial complimentary phone consultation (833-376-6445) will help assess a patient’s likelihood of benefiting from high-powered low vision glasses or devices.
