Specific testing for children.
Visual Acuity at Distance and Near – most school screenings just test a child’s distance vision which may not pick up a child who is hyperopic (farsighted).
Cover Test – is used to check the alignment of the eyes, or for any signs of strabismus. Children or adults with some variation in the alignment of their eyes may complain of headaches, dizziness, double vision, or difficulty with near work.
Accomodation – is the ability of the eye to focus on near objects. All children should have the ability to focus up close, but like other muscles in the body, may take some exercises to strengthen those focusing muscles. Children with accommodative issues may complain of near vision blur and headaches, or distance vision blur after reading or studying for an extended period of time.
Convergence – is the ability of the eyes to turn in when looking at near objects. An individual who has insufficient convergence may complain of headaches, double vision, eye strain, intermittent blur, and difficulty with near work.
