If you have low vision and you are looking for a magnifier, you will quickly encounter two fundamentally different categories of products: optical magnifiers and electronic magnifiers, also called CCTVs or video magnifiers.
Both help people with low vision read and see more clearly. They work differently, cost differently, and fit different tasks and lifestyles. This guide explains what each type does best and how to decide which option fits your specific vision needs.
What Is an Optical Magnifier?
An optical magnifier uses a glass or plastic lens to enlarge what you are looking at by bending light. It does not require charging or electronic controls. You position the lens over an object or printed material to make it appear larger.
Optical magnifiers range from simple handheld lenses to stand magnifiers that rest on the page, illuminated magnifiers with built-in lighting, and bar magnifiers that help highlight a line of text. They are compact, affordable, and immediately usable.
Optical magnifiers are best for:
- Quick reference tasks such as checking a price tag or reading a label
- Restaurants, outdoor settings, and other places where electronic technology may be impractical
- People who prefer a simple magnification tool
- Travel and portability
- Lower-cost magnification needs
Limitations of optical magnifiers
- Magnification is generally lower than electronic options
- Illumination is limited unless the magnifier includes its own light
- The usable viewing area becomes smaller as magnification increases
- Traditional optical magnifiers are designed for near tasks rather than distance viewing
What Is an Electronic Magnifier or CCTV?
An electronic magnifier uses a camera to capture an image and display it on a screen at adjustable magnification. Because the image is digital, you can change magnification, contrast, color modes, and other display settings to better match your vision.
Electronic magnifiers generally fall into two categories: portable handheld models and larger desktop systems designed for sustained reading and other close-up tasks.
Electronic magnifiers are best for:
- Sustained reading of books, newspapers, mail, and paperwork
- People whose preferred magnification level changes by task
- Progressive or complex vision loss
- Customized color and contrast settings
- Distance viewing when the device includes a distance camera
- Home, school, and workplace reading stations
Limitations of electronic magnifiers
- Higher purchase cost than most optical magnifiers
- Controls and settings require some familiarization
- Portable devices require charging
- Desktop models take up more space and are less convenient to carry outside the home

How to Decide Between an Optical and Electronic Magnifier
Choosing the right magnifier starts with understanding your vision, not simply choosing a product. A low vision evaluation can help determine whether an optical magnifier is appropriate, what strength you need, and whether electronic magnification or enhanced contrast features would better support your daily tasks.
Step 1: Schedule an evaluation with a low vision specialist
In addition to continuing care with your ophthalmologist and any other eye-related specialists, find a low vision specialized optometrist near you for a functional vision evaluation.
A low vision specialist looks beyond the medical diagnosis to understand how your remaining vision affects everyday activities such as reading mail, identifying medication labels, writing checks, viewing photos, cooking, or completing work and school tasks.
This evaluation can help determine whether a handheld or stand optical magnifier is appropriate for you and identify the magnification strength that best supports the tasks you want to complete.
Step 2: Learn how to use the optical magnifier that is recommended
Getting the correct magnification strength is only part of the process. Positioning, working distance, lighting, reading technique, and how you move the magnifier across the page can all affect how well an optical magnifier works in daily life.
At The Chicago Lighthouse, our comprehensive low vision services within our locations can include training on how to use handheld and stand optical magnifiers for everyday activities. This helps connect the magnifier selected during your evaluation with the practical skills needed to use it at home, school, work, and in the community.
Step 3: Determine whether optical magnification meets your everyday needs
After evaluation and training, consider whether an optical magnifier gives you enough access for the tasks you complete most often.
Optical magnifiers can work well for quick reading tasks, labels, menus, mail, and other close-up activities. If you need significantly more magnification, a larger viewing area, longer reading sessions, or the ability to change magnification frequently, your needs may extend beyond what an optical magnifier provides comfortably.
At that point, an electronic magnifier evaluation can help identify additional options.
Step 4: Evaluate whether electronic magnification and enhanced contrast would help
If optical magnification does not provide enough access, The Chicago Lighthouse's Assistive Technology team can help evaluate electronic magnification options based on your vision and daily activities.
Electronic magnifiers provide adjustable magnification and display features that optical lenses cannot provide. These can include high-contrast viewing modes, inverted contrast such as white text on a black background, adjustable brightness, and different color combinations.
People with macular degeneration and other conditions that affect contrast sensitivity can especially benefit from evaluating these display options rather than selecting an electronic magnifier based on magnification level alone.
Step 5: Match the electronic magnifier to where and how you will use it
Once electronic magnification has been identified as appropriate, consider the environments where you need it most.
If you primarily read books, mail, paperwork, recipes, or other materials at a table or desk, a desktop electronic magnifier such as the Vario 16 is designed for sustained near viewing.
If you need magnification for menus, labels, appointments, stores, classrooms, signs, or other activities away from a desk, a portable electronic magnifier such as the Humanware Explore 8 provides adjustable magnification in a smaller form factor.
Some people use both because a desktop and portable magnifier solve different problems.
Step 6: Consider budget, funding, and long-term needs
Once you know which type of magnification works for your vision, compare the options that meet those needs with your budget and available resources.
Optical magnifiers are generally less expensive than electronic magnifiers. Electronic devices represent a larger investment because they include cameras, digital displays, adjustable magnification, contrast controls, and other technology.
Ask your low vision specialist or Assistive Technology specialist about funding resources that may apply to your situation, including vocational rehabilitation programs or other assistance available in your area.
The goal is not to purchase the most advanced magnifier. It is to identify the level of magnification, contrast, portability, and training that best supports the activities you want to complete independently.

Frequently Asked Questions About Optical and Electronic Magnifiers
These questions address some of the most common differences between optical magnifiers, portable electronic magnifiers, and desktop CCTVs.
What is the difference between a CCTV and an electronic magnifier?
They belong to the same general category of assistive technology. CCTV, short for closed-circuit television magnifier, is a longstanding term for a video magnification system. Electronic magnifier and video magnifier are also commonly used. Larger desktop systems are often called CCTVs, while smaller portable devices are often called electronic magnifiers.
What magnification do I need for macular degeneration?
The appropriate magnification depends on your visual acuity, contrast sensitivity, reading goals, and the size of the material you need to see. A low vision specialist can help determine an appropriate starting level. Electronic magnifiers such as the Humanware Explore 8, with 2x to 30x magnification, and the Vario 16, with 1.3x to 45x magnification, allow you to adjust enlargement for different tasks.
Can I use an electronic magnifier for watching TV or distance viewing?
Some portable electronic magnifiers support distance viewing. The Humanware Explore 8 includes two HD autofocus cameras, including a camera for distance tasks such as viewing a sign, presentation, or other material farther away. Desktop systems such as the Vario 16 are primarily designed for near tasks at a desk or table.
Is an electronic magnifier worth the cost?
An electronic magnifier is most useful when its adjustable magnification, display size, contrast settings, or other digital features directly support tasks you complete regularly. Someone who reads books, mail, paperwork, or other print for extended periods may benefit from those features more than someone who only needs occasional help reading a short label. Comparing the device with your actual daily tasks is the best way to judge its value.
Does insurance cover electronic magnifiers?
It is often the case that public and private insurance do not cover electronic magnifiers or other assistive technologies because they are not directly considered Durable Medical Equipment (DME). It should be said that coverage and funding options may vary for individual circumstances. Vocational rehabilitation programs and other third party funding resources may help some people obtain assistive technology. Ask your low vision specialist or The Chicago Lighthouse about resources that may be relevant to your situation before assuming a device will or will not be covered.
