[Galina]

The son (11 years, a myopia - 2.5, advance - 0.5 dptr in a year) is engaged in DJUSSH in navigation. Practically is not ill or sick with catarrhal diseases. But it can be harmful employment or occupations to eyes and they should be stopped?

[Ryzhkov S.V.]

I do not see anything bad in employment or occupations by navigation. Here in weightlifting, a bar to him to be engaged it is undesirable. Certainly, virtually to tell or say difficultly, not seeing an eyeground. But I think, no changes there still are present.
And voobshche-that I recommend to make to the child a scleroplasty.

Yours faithfully, d. M. n., professor Ryzhkov With. Century
