Visual Acuity - what does it mean?
- Acuity can be estimated from infants and those with communication difficulties using special techniques that measure resolution acuity more
- Recognition visual acuity is the type of acuity measured from someone who is able to match or name pictures or letters more
- If you have a recorded visual acuity (e.g. 6/60 or 20/200) these web pages should allow you to obtain a printout of the size of images that should be seen easily at different distances. Please follow this link to learn more.
- Visual acuity is usually recorded as a Snellen fraction such as 6/60 (UK) or 20/200 (US) more
- Other ways of recording acuity e.g. cycles per degree and LogMAR may be converted to Snellen fractions more
Visual Acuity - What does it mean?
Visual acuity describes how well you can see high contrast detail in the centre of your vision.
If you have a recorded visual acuity (e.g. 6/60 or 20/200) these web pages should allow you to obtain a print out of the size of images that you should be able to see easily at different distances.
A person’s visual acuity reflects only one aspect of their vision. There are many other aspects of vision such as refractive error, accomodation, contrast sensitivity, cognitive visual function, visual fields and eye movements which will all impact on how well a person sees and uses their vision.
