How does CCTV help people with Low Vision?

The CCTV system is a highly adaptable and customizable technological device that can greatly enhance the quality of life for people with low vision. CCTV is an electronic magnification technology which projects images on a monitor, making it easier for people with low vision to read for extended periods of time. There is a range of different kinds of Video Magnifiers, but what they all have in common is that they contain a camera that magnifies and projects images onto a screen.

This device is made to be user-friendly for both those who are comfortable with technology and also for people who are less accustomed to using digital devices. If you find that your vision challenges are preventing you from living the life you want, you can speak to your low vision eye doctor about the CCTV which was created to help you and your personal vision needs.

Types of Video Magnifiers

There is a wide range of CCTVs available, made by various companies. There are different types of Video Magnifiers, some are portable and others are stationary, as explained below.


Types of Video Magnifiers

Handheld CCTV Magnifiers

Handheld magnifiers are great for those who need vision assistance while on the move, whether it’s for activities around the house like reading recipes, playing cards, or looking at a computer screen. These smaller magnifiers tend to be somewhat cheaper than large desktop models. However, being handheld devices, you need steady and available hands to hold them and they need to be charged.

Stand Video Magnifiers

Some Video Magnifiers come with stands and there are different kinds available. Some CCTVs come with four legs so that it can be placed on a book without having to be held. There are other magnifiers that have a handle, but they don’t always need to be held as they can be placed on a page in order to support itself. When the CCTV has a stand, the stand is already set to be at the perfect working distance from the text which means that when you use it, you don’t have to adjust it. A Stand Video Magnifier is ideal for a person who does not have the stability of holding an object in a steady fashion due to limited motor skills which could be a result of a wide range of conditions, including Parkinsons.

Desktop CCTV Magnifier

Desktop CCTV magnifiers have several advantages over portable magnifiers, for people who need them for reading and other tasks while at home. In addition to being hands-free and not requiring charging, they are more powerful and also larger. This means that they can also magnify more text at a time. They are also adjustable so that you can properly position the device over the text or other objects you need magnified.

Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

Thank you!

When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
