visual acuity• Contact lenses sometimes give better visual acuity in these cases and the field of vision is nearly always improved.• Here, visual acuity is not so sharp, nor is our ability to judgedistances so good.• The amount of pigmentation tends to increase slightly with age up to adolescence and brings with it a gradual improvement in visual acuity.• In measuringvisual acuity in this way, a figure which looks like a fraction is recorded.• The simplified scale in Figure 1 gives an indication of the range of vision as described in terminology based on visual acuity.• Such vision would be recorded as 6/60 and would indicate severely reduced visual acuity.
