FAQ
The evaluation of visual impairment requires the measurement of visual acuity with a validated and standard logMAR visual acuity chart. Near vision logMAR chart help check the vision power of a person while reading.
In the logMAR, visual acuity is reported as a single number where 0.0 is standard vision. Visual acuity decreases as the number increases and improves as the number decreases.
A normal eye is considered to have a near point at about 11 cm (4.3 in) for a thirty year old.
LogMAR visual acuity charts are widely recognised as providing the most reliable and discriminative VA measurements.
logMAR format tests offer the advantage of consistent test-retest variability across the acuity range. This means that one can identify in terms of numbers of letters or lines, a minimum change which might be considered significant and which might be applied regardless of the underlying acuity.
