Less power with age: As he grows, so also the eye will grow and these numbers will diminish. Since he is balanced he will maintain good vision in each eye. Unless there is some internal disease process, he will not go blind from these eyeglass powers.

Hyperopia and Blur: Blindness is a loss of vision, but refractive errors, even high hyperopia, does not cause blindness. The real risk is amblyopia or lazy eye. The high hyperopia requires the use of spectacles, and possibly even bifocals, with the goal of preventing accommodative esotropia, an inturning of the eye, with one eye becoming amblyopic. The refinement of the prescription is par for the course.

Common problem: Also, as he does not have to focus his eyes with the glasses, it is quite common to "uncover" a little more farsightedness after he starts to wear glasses for the first time. Don't worry, the prescription will most likely diminish over time.

Hyperopia: Your child is hyperopic to a rather high degree. This is in no way related to blindness. The glasses should provide very good vision. You should have him followed yearly by an ophthalmologist to make sure good vision is maintained and no other problems are present.
