Who Knows How to Test Children’s Vision?
Many health professionals are specially trained to assess vision.
Some will have the additional training or expertise required to assess children’s vision, particularly pre-verbal children. Different countries, or even states and jurisdictions within the same country, may have different personnel who have this training. Traditionally orthoptists, optometrists and ophthalmologists are the key personnel who have specific training, although many nurses and community health workers may also be well-trained.
How Is Vision Tested?
The most familiar method to test vision is simply reading letters on a vision chart. The smaller the letters read, the better the central vision.
Children with retinoblastoma will often be too young to read a vision chart, however there are myriad other ways in which their vision can be tested.
