Low vision refers to a reduced level of vision measured on the sight testing charts which is attainable with the best possible spectacles. Patients with low vision can struggle with simple daily tasks due to the changes in their vision.
There are many eye conditions that can cause low vision for different reasons. Some examples of these conditions are age-related macular degeneration, diabetic retinopathy and maculopathy, retinitis pigmentosa and albinism. These conditions affect the eye in different ways, therefore it is important that the impact is fully understood in order to utilise the best possible vision available.
At a low vision assessment, the conditions that affect the eyes can be discussed in full to determine the best possible help for each individual patient. It is useful to attend the assessment with a few daily tasks with which the patient is struggling. Throughout the appointment, different low vision aids can be tried to see if the task can be made easier. For example, if a patient struggles with reading the cooking instruction on food packaging we would be able to try different magnifying glasses of varying strengths until the most suitable one is selected. Although the low vision aids can be very useful, we would also discuss other practical ideas for the home which may make daily tasks less difficult such as lighting, use of colour codes and tactile cues.

A low vision aid is a piece of equipment that can be used to enhance the vision. There are many optical low vision aids such as magnifying glasses and telescopes which come in a variety of shapes, sizes and strengths. Other low vision aids that are available range from speaking clocks to large print board games and tactile stickers. At a low vision assessment, the different types of aids can be discussed along with their advantages and disadvantages until the right ones are found for the patient.
There are a range of optical low vision aids to try (shown in the image above) which include hand, stand and electronic magnifiers.
