女人心,
My situation is exactly the same as you. My son also has 散光 in the range of 200-300o.
We bought the 3M light right in ~Jun. Not sure the impact yet. But at least it is much brighter for the studying/working area.
I think 散光 is naturally born due to the shape of the cornea and I hope if we help him to control well, it will not increase further.
would appreciate the other parents can share.
