How much your child can see to the sides when looking straight ahead is reduced by around 20 per cent. However, your child’s ‘good’ eye can see far into the other half of the visual field and helps to make up for the sight loss in the other eye. Your child will also learn to turn their head to make use of their vision – although there will still be a limit to what they can see over their shoulder on their blind side.
Having sight in only one eye means your child doesn’t have 3D vision and depth perception. This is essential for judging distance, for example, judging the height of steps or correctly pouring liquid into a cup.
