Low Vision Magnifiers And Their “New-Age” Alternatives
Last updated: October 4, 2021
Low vision magnifiers are optical devices that assist people with low vision to perform daily activities, by magnifying or enhancing vision. Magnifiers include a wide range of devices, including hand-held devices, stand magnifiers, high-powered reading glasses, video magnifiers, and more. These styles of magnifiers usually vary according to their purpose of use and are different from regular glasses or commercial magnifiers. If you’re in the market for a magnifier device, know that there is no “one size fits all” approach. There are several factors to consider in your selection process. This article covers the different types of magnifiers available for low vision, how you can choose the right magnifier, and high-tech alternatives to magnifiers.
Types of Low Vision Magnifiers
There are 6 general types of low vision magnifiers:
- Video camera magnifiers
- Hand-held magnifiers
- Stand magnifiers
- Magnifiers mounted atop glasses
- Low vision reading glasses
Low-Tech Magnifiers vs High-Tech Magnifiers
Low-tech magnifiers are simple devices, such as hand-held magnifiers (such as a magnifying glass), that are relatively easy to use by people with vision impairment. However, they do have a limited function as the field of vision tends to be small with this kind of magnifier.
High-tech magnifiers, however, use technology to improve the sight of people with low vision. Examples of high-tech magnifiers include desktop video magnifiers and portable video magnifiers. High-tech magnifiers can greatly improve vision, but are typically more expensive and may not be suitable for people who struggle with technology.
Telescopes have magnifying powers from 2x to 10x and can assist people with low vision to carry out tasks at both close and distant ranges. There are several types of telescopes available including hand-held, clip-on, head-wear, bioptic, and more. Telescopes are portable, making them suitable for people who need assistance with on-the-go, short tasks, such as reading the newspaper headlines. However, telescopes offer only a narrow field of vision.
Portable Video Magnifier
A portable video magnifier is a compact, electronic, hand-held magnifier that is relatively easy to use and carry. Like handheld magnifiers, portable video magnifiers allow the user to easily read items in their environment, like a label, menu, or map. Since portable video magnifiers are small in size, their field of vision is narrow. Also, note that because they operate using batteries, portable video magnifiers are not well-suited for long periods of use.
A hand-held magnifier is best used for on-the-go, quick spot reading. For example, a handheld magnifier is useful for reading fine print such as price tags and viewing menus. Handheld magnifiers vary in size from small, portable pocket magnifiers to a 5.5 inch full-size one. Sometimes, magnifiers will have built-in light to make reading easier. However, handheld magnifiers are not suited to all tasks, especially those requiring object magnification at a distance. Ranging in price from $5 to $150 USD, handheld magnifiers are the most affordable version.
Stand magnifiers are ideal for tasks that are longer in duration, such as reading a novel or magazine. Stand magnifiers are popular due to their affordability ($30-$150 USD) and suitability to people who have trouble with hand-held magnifiers. However, stand magnifiers are not recommended for portable use cases.
Desktop Video Magnifier
Desktop video magnifiers use a built-in camera lens to display highly magnified images on a computer desktop screen or a video monitor. This kind of magnifier allows the user to modify the image to their preferences, with options to adjust magnifying power, brightness, contrast, and color of the display according to user requirements.
Desktop video magnifiers typically require a power outlet, so they are rarely portable, and they also tend to be more costly, with an average price tag of $3,000 USD.
What Magnifiers Can Do For Your Low Vision
If you have low vision, magnifiers can greatly improve your vision and ease of performing everyday tasks. A low vision specialist, such as an optometrist can help you identify the correct device for your needs.
Magnifiers are known to improve vision for people with the following conditions:
Although magnifiers for low vision are effective, you may require different types of magnifiers for different tasks. For example, a hand-held magnifier can help you to scan maps and labels, but a stand magnifier would be more suitable for reading a book.
All-In-One Assistive Technologies
All-in-one assistive technologies, such as eSight, have led to breakthroughs in vision improvement. Assistive technologies are easy to use, have a wide range of applications, and offer great flexibility to the user. eSight is worn comfortably like glasses and offers immediate enhanced vision plus easy to use advanced vision controls. Used by thousands of people with visual impairments daily, eSight includes 24x zoom magnification; focus, contrast, and brightness controls; and patented bioptic tilt. Learn more about eSight.
Choosing The Right Magnification Device
There are many factors to consider when choosing the right magnification device for low vision, such as your current level of vision, what your needs are and personal comfort levels.
Your Vision: Visual Acuity And Low Vision Condition
While magnifiers for low vision are effective, you will likely require multiple types to meet all of your needs as one size does not fit all. One magnifier is unlikely to fulfill all of the functions you require in your daily life. You would need to buy a pair of low vision reading glasses, a handheld magnifier, and a stand magnifier just to be able to read your favorite novel, go shopping, and study.
What You Are Trying To Achieve with your Low Vision Magnifier: Lifestyle And Personal Goals
Magnifiers with higher power typically provide you a small field of vision. This can limit what you are trying to achieve. For example, if you are trying to read a novel, it will allow you to visualize only a part of the page instead of the entire page for easy reading. This can be an inconvenience for those who require high power magnifiers, who are now restricted to seeing only a fraction at a time. Your lifestyle, hobbies, and personal goals also determine what kind of device you need.
Low Vision Magnifiers for Students
For students with low vision, it is important that the magnification device allows them to spend prolonged periods of time reading, learning, writing, or viewing screens. As such, a desktop video magnifier would be an ideal solution.
Low Vision Magnifiers for Seniors
Seniors typically require high-powered magnifiers that are portable and easy to use. This makes head-worn magnifiers an ideal candidate.
Low Vision Magnifiers for Work
Workers with low vision require task-specific magnifiers that are suitable for their job. For example, someone who works at an office may find desktop video magnifiers more appropriate, while a mechanic may require magnifiers that are head-worn or special eyeglasses with high magnifying power.
eSight® – The Award-Winning “All-In-One” Alternative to Magnifiers
eSight, a head-mounted assistive vision enhancement device, is the most versatile and advanced all-in-one device for people with visual impairment.

Trusted By Doctors
Eyecare specialists and ophthalmologists trust eSight to provide the best low vision assistance for their patients.
Dr. Robert Devenyi, an ophthalmologist at the University Health Network, has attested to the life-changing possibilities of eSight for his low vision patients:
eSight opens up a whole new realm of possibilities for low vision patients and allows us to help them in ways we never could before.
The eQUEST (eSight Quality of Life Efficacy Study), completed in collaboration with researchers at six leading universities, including John Hopkins University and Bascom Palmer Eye Institute, proved that eSight improved distance acuity, reading performance, contrast sensitivity, facial recognition, and activities of daily living (ADLs) for people with vision loss
eSight also demonstrated:
- 100% mobility retention
- A 7-line gain in distance acuity
- A 12-letter contrast improvement
The results of our study indicate significant improvement in a number of validated visual performance measures. More importantly, study participants reported much improved day-to-day visual ability when using eSight.Dr. Gislin Dagnelie, Associate Professor of Ophthalmology, John Hopkins University School of Medicine.
eSight is a Class 1 Medical Device. It is registered with the European Databank on Medical Devices (EUDAMED) and the Food and Drug Administration (FDA) and inspected by Health Canada.
