Visual Hygiene: What for?

Hi everyone!

Previously, we has discussed on how near work can induce myopia. Have a look at this again. Clinicians have long recognised that sustained periods of near work tend to induce myopia in susceptible individuals. Many researches suggest that accommodation plays a critical role in the progession of myopia.

Can we actually control the progression of myopia? Yes, sure!

There are few alternatives that practitioners or you can do beside using optical form of therapy. Try this, Visual Hygiene.
Visual hygiene is simply to say an activity that one person can do to relax his accommodation, so that the myopia is controlled.
