CCTVs include a monitor and camera that may either be fixed or portable, some models including features like text-to-speech technology and OCR for reading printed texts.

CCTVs are low vision devices designed to magnify for use in many tasks such as spot checking, reading, writing and viewing photographs as well as medication management and hobbies.


People with low vision often require magnifiers to increase the size of text and objects they see, whether because they cannot read printed words, can only view handwriting at reduced size or cannot perceive photographs or visual images. Magnifying devices may either rely on magnifying properties in glass or plastic lenses or use electronic methods with cameras that project an enlarged image onto a screen; typically it’s best to own both for maximum flexibility in daily activities.

There are two types of portable electronic magnifiers: standard desktop CCTVs (CCTVs) and handheld magnifiers. A desktop CCTV typically measures 17-24 inches in size and weighs 30-50 pounds; its monitor displays full magnification capabilities, contrast/brightness control settings, reverse polarization functionality, as well as additional screen color options.

A handheld magnifier features a more portable design that is easier to carry around, making it suitable for patients who must use their magnifier in multiple locations such as work, school, church and home. Furthermore, these handheld magnifiers also come equipped with touch screens similar to mainstream tablet computers for ease of operation.

ClearView GO is an electronic magnifier designed to offer both reading comfort and user convenience with the added feature of self-view mode allowing them to use it for personal grooming, watching television or listening to music.

When purchasing an electronic magnifier for low vision, it’s essential to understand the differences in magnification strengths. A higher magnification power might be useful for reading labels on medication bottles but may reduce the number of words appearing on screen. A low vision specialist can assist in selecting an electronic magnification solution best tailored for you – they will bring various models directly into your home so you can try them all out and find one that meets your individual needs. Ask questions and become involved with the process – asking questions may lead you in the right direction when choosing what electronic magnification device is appropriate for you!

Text to Speech

CCTVs are electronic devices designed to magnify reading, pictures, and objects at much higher magnification than handheld magnifiers. A CCTV can help people who have limited vision by substituting for Braille or large print reading methods like tapes, scanners, electronic text readers or sighted readers; or be an additional tool in their reading arsenal.

As it pertains to medical equipment, CCTVs should only be prescribed by a doctor as part of a treatment plan. This differs from electronic tablets or laptops which may only be used for entertainment and therefore do not qualify under Medicare’s DME definition. Usually a physician will recommend CCTV as treatment for specific eye conditions in their care plan and include it accordingly.

There are different kinds of CCTVs, some which utilize the screen and power of a computer to interact with documents and images. These devices can be connected to monitors for viewing; many also come equipped with USB ports for uploading files directly onto computers for storage and saving. Used to read documents, play games or work on projects these cameras may prove costly but with proper training can become highly proficient tools.

Other CCTVs are designed for portability. These devices tend to be smaller and lighter than desktop computers, though not as portable as smartphones or tablets. They usually offer magnification with features like line markers and window masking to assist in following lines of text more easily; some models even connect directly to computers for project collaboration without sighted assistance needed.

Technology continues to offer more options to assist those living with low vision, making eye care professionals aware of any new devices or resources which might benefit their patients’ daily lives. By including such devices into treatment plans, eye care practitioners can help their patients reenter society more seamlessly.


Optometrists now have more choices when creating care plans for their patients thanks to low vision device cctv technologies. These devices offer software and features to scan, read and convert printed documents into speech or braille – as well as live images being captured from cameras that beam them back directly to users – providing many ways for optometrists and optometry practices to assist their patients. Furthermore, many low vision devices also double up as computer monitors allowing those living with low vision regain independence through resumed activities while increasing independence allowing them to resume activities previously enjoyed prior to being diagnosed cctv can transform lives; improving lives of those living with low vision by enabling them to resume activities previously enjoyed prior to diagnosis allowing optometry offices or optometry practices by becoming independent more quickly in care settings than would ever been previously possible prior.

Eye care patients typically seek help when they are having difficulty with specific tasks, most commonly reading. Such difficulties can result in decreased quality of life, increased anxiety and depression levels, as well as feelings of social awkwardness; many of these symptoms can be avoided or minimized with simple environmental modifications and low vision devices such as placing children near windows for natural lighting during reading can make a big difference in their ability to see; similarly using felt-tipped pens with thicker lines may aid visually impaired in writing better and reading their own handwriting better.

Low Vision Device CCTV may be an ideal solution for individuals having trouble reading due to macular degeneration, stroke, glaucoma, retinitis pigmentosa or other visual impairments. The technology combines a video camera and large screen that magnify materials up to 131 times for reading convenience; additionally it can convert printed text to audio for spoken aloud reading as well. Both portable models and self-contained units are available which can be used at home or work environments.

Some VA programs that prescribe CCTVs and EOEDs follow guidelines to ensure veterans receive clinically necessary devices, including CCTVs and EOEDs. These guidelines require patients demonstrate they need them, with evidence that this device will help achieve their goals using remaining vision. Furthermore, programs must implement a documented procedure for evaluating all available devices to evaluate whether they meet patient goals, such as training on using it effectively as well as home trials of equipment.

Touch Screen

Touch screen CCTVs can be invaluable tools for visually impaired individuals. Their touch screens enable users to scan, read, write and interact with computers using this device; you can even use them to magnify text and images as well as writing checks or filling out forms. Some CCTVs also come equipped with speech output that will read back the printed word aloud; this feature may prove especially helpful for people with hearing loss who cannot read braille.

Desktop CCTVs are the workhorses of low vision electronic magnification technology. Their size ranges from 17-24 inches and weight between 30-50 pounds; though somewhat cumbersome in terms of portability, their larger frame enables significantly enlarged words or images to fit on monitor screens.

Portable CCTVs feature smaller monitors that can be easily carried around in a bag or pouch, making them great for active people on-the-go all day. Unfortunately, their limited durability means they often get bumped and dropped, and may need repairs after repeated uses; additionally they may only offer limited magnification capabilities and require extra battery power in order to function.

New CCTVs are being introduced that go beyond simple magnification. Some models combine features of both, including Screen Readers that use Optical Character Recognition (OCR) technology and CCTVs, so as to magnify and read your image on screen to you simultaneously. Additional features may include line markers or window masking that darken areas above and below lines of text to emphasize them as you read.

The VA regularly issues CCTV devices to blinded veterans. It helps them perform daily tasks, such as reading mail, books, magazines and newspaper articles; writing letters; taking medication; preparing meals; shopping; and playing games.

As part of a CCTV evaluation process, it is critical to consider an individual’s specific visual needs and limitations. Some can utilize the device with minimal difficulty while others find it more challenging or impossible. It is also crucial that a CCTV wouldn’t interfere with an individual’s educational development – for instance some legally blind children might be encouraged to use CCTV instead of learning Braille which may compromise their academic success.
