Clear and Sharp
Eye Sight

Visual acuity is the clarity and sharpness of your sight.
It varies greatly from person to
person and in many cases can 
be managed with prescription glasses.

Poor Visual Acuity

A lack of visual acuity could be due to an eye condition such as short or long-sightedness, presbyopia or astigmatism. These conditions are easily treatable with prescription glasses.

Managing poor acuity is especially important for drivers. To drive safely, your vision must pass the minimum vision standard set by the DVLA. Certain occupations demand higher standards.


Signs of
Low Vision

Signs you may have a problem include loss of central vision - blind spots appear at the centre of the field of vision; loss of peripheral vision (‘tunnel vision’) – an inability to see to the side; blurred vision – objects appear out of focus or hazy at certain distances; poor night sight and sensitivity to glare.

Eye Conditions

Low vision can stem from a number of conditions or injuries, such as diabetes or a brain injury.
It can also be related to other eye conditions, which are listed below.


Glaucoma is a group of eye conditions in which a build-up of eye fluid damages the optic nerve.

Did You Know?
The Snellen Test

What is 20/20 vision?

Dutch ophthalmologist Dr Hermann Snellen devised his eye chart of different sized  
letters in 1862, specifically to measure visual acuity. The term 20/20 vision, is a reference  
to being 20 feet away from the eye chart. When metric took over, this term was  
replaced with 6/6 vision, as the test is conducted from 6 metres away.  
But this doesn't mean you have perfect vision. The test  doesn't take into  
consideration peripheral vision, colour definition or the depth of your perception.
