Hello, Although your son has significant astigmatism, the fact that he s young can compensate his vision up to a certain point, as the lens we all have inside the eye is more flexible in children. That s why he can see near and far apparently very well. That being said, a bilateral astigmatism greater than 2.50 Diopters is a cause of isoametropic amblyopia. A more common name for amblyopia is lazy eye . This means that if he doesn t wear glasses, although he can partially compensate the astigmatism now, a normal visual acuity would not be reachable once he is older, with the consequences that an impairment in vision would bring. I would strongly suggest an examination by a Pediatric Ophthalmologist, as the result for treating refractive amblyopia is better, the sooner it is treated.
