Visual Factors in Dyslexia

Problems with sight are not usually a main cause of dyslexia, however some visual problems do occur more often in dyslexic children and these may contribute to the reading difficulty.

This type of visual problem may be missed in a school eye check, so a full eye examination is always recommended. Visual problems may be constant or intermittent, occur at distance ( writing on the board at school or, for adults, road signs in the distance) or when reading or writing in a book. Sometimes dyslexic people notice that words in a book may go blurry, jump around, go smaller/bigger, fade or disappear, or get faint colours round them. Sometimes, double vision may occur, and sore or tired eyes.
