Jules van Els

Jules is an optometrist who focuses particularly on the field of binocular vision detection and procedures. He is especially good at finding solutions for binocular vision problems experienced by people with whiplash, dyslexia and asthenopic complaints related to fixation disparity – i.e. situations where out-of-focus vision is the main cause of symptoms. 

Jules uses the procedure according to Dr Haase, a step-by-step process that looks at themotoric and sensory function of the human eye. He is a genuine problem solver who often finds solutions for non-adaptation patients.
