Assistive technology resources

There are much more technologies available in the market that we can imagine for people living with Leber’s Hereditary Optic Neuropathy – LHON, who manifest vision loss symptoms and need to perform certain adaptations. And the options keep increasing.

Thanks to this resources people living with LHON can start reading again, as well as writing, using smartphone apps, studying, working, and performing many ordinary daily activities that would seem impossible.

There is a wide variety of assistive technologies available for people with visual impairment and the options continue to increase.


With appropriate magnification, as with a CCTV, you can project texts in a screen, which allows many of those with LHON to read

Computers, smartphones, and tablets

Currently, most computers, smartphones, and tablets have accessibility mechanisms. Smartphones and computer software such as ZoomText, Kurzweil, and JAWS, as well as the integrated accessibility resources on Apple products, are used.

Accessibility on Windows operating system

Windows provides a menu of accessibility functions that may be used for different objectives, such as for people with some disability, problems with basic computer resources, or improvement on navigation in general. Check out below the accessibility functions:


It is used so a voice reads the screen contents. The voice may be personalised according to user preferences, allowing to choose between a male or female voice, changing the speech speed, and even what content will be narrated.


It allows the user to increase the zoom over some content of the screen. The user may define the zoom percentage of the tool, as well as select where they want to apply it.

High contrast schemes

It facilitates the visualisation of the content for those that are visually impaired. It has many different high contrast schemes, such as the one on the image below:

On-Screen Keyboard

It is possible to activate an on-screen keyboard, which is very useful for those who have a touchscreen device and do not want to use a traditional physical keyboard, for example, as well as other possible key configurations.


If you do not own a mouse, or if it stopped working, you can configure on this menu options to access it through the keyboard. Besides, you can also define the size of the pointer.


Amazon has many devices with voice activation, as well as other accessibility options. Some examples are Echo, Dot, and Alexa.

Each person’s vision is different and it is important to test every product to determine which is more effective. Some interesting relatively new electronic glasses include:


With a built-in camera, the accessory connects to human agents that describe the environment to the visually impaired person and help them with basic chores, like calling a cab or an Uber, navigating on websites, etc.

eSight Eyewear

This is one of the multi-function electronic glasses, which include high definition magnification, electronic texts reader, internet access, electronic projection on the lenses, etc. For other information, visit the product’s official website:


OrCam MyEye 2.0 was developed to give more autonomy to blind or visually impaired people and can recognize texts, people, products and bar codes, money bills, and colours. It can also inform the date and time by turning your wrist. It allows easy access to real-time information confidentially.


Books and texts in a digital format is another form of reading. There are many free access to electronic books services. With the text in a digital format, you can use your device’s (computer, smartphone, or tablet) screen reader and be able to read practically any text.

Other options are the Institutes for visually impaired people’s digital libraries. In Brazil, Fundação Dorina has a wide book and audiobook collection on many themes. For more information, visit “Dorinateca”.

Glasses that can read and make facial recognition

Text recognising cameras that magnify them on screen are a fantastic option for visually impaired people, but the OrCam raises the concept to another level. It is a camera that can be fixed on a pair of regular glasses that later connects to a small computer that can be carried in your pocket. With a simple hand gesture, OrCam can recognise text, reading it to the user through a small earphone. Additionally, OrCam also recognises street signs, menus, money bills, and even faces. OrCam helps blind and visually impaired people being more independent and tends to become even faster and more useful in the future.

MyTherapy: The Accessible App

It is simple and accessible for everyone, as well as compatible with VoiceOver and TalkBack.

Apps that make life more accessible


It scans products’ bar codes and speaks (in the chosen language) details such as the ingredients or the brand.


It detects objects and speaks their names aloud. It works as a reminder of medicines, as well as a health journal registering all symptoms. It is also accessible to visually impaired people.

VoiceOver e TalkBack

They are screen readers of Apple or Android smartphones.

Be My Eyes

This application is maintained thanks to the volunteers’ community spirit and willingness to help others. When a visually impaired person needs help, either for reading the expiration date of the milk or to cross the street, this person can use the app to connect to a volunteer and ask for help through a video call. The person on the other side of the line lends a bit of their time to help, making the everyday obstacles easier to go through by the user.
