What Low Vision Aids (LVAs) are
A low vision aid (LVA) is a device that increases a child or young person’s visual access.
Types of LVAs
LVAs can be grouped in two basic categories.
Near LVAs
These are for close-up, detailed activities such as:
- reading
- writing
- crafting
Most LVAs may isolate, bring closer or magnify an image or text.
Others have more sophisticated functions, for example they can:
- change the background colour or the font colour
- provide more light
- provide a higher level of contrast
Distance LVAs
These are for activities which are further away such as:
- reading street signs
- identifying numbers on buses
- seeing the teacher
- accessing a whiteboard
Some distance LVAs just bring a distant image closer. Others can:
- change colours of the image
- change the level of contrast
- freeze the image
Examples of LVAs
LVAs can be further subdivided into:
- those that may be recommended by a Qualified Teacher of the Visually Impaired (QTVI) or
- specialist magnifiers that might be prescribed by an orthoptist through a low vision clinic
LVAs that might be recommended by a QTVI include:
- typoscope
- reading ruler
- sloping desk
- specialist electronic magnifiers with a camera and big monitor, often coming with a specially designed worktop
An orthoptist will:
- assess individual needs by taking into consideration:
- tasks performed by the patient
- the nature of the vision loss
- prescribe appropriate LVAs, as some people may use more than one
