Not really a comfort.

My D 's eye jump from 75 degree to 300 degree in one year at age 9. Since she wear CRT for 7 years, her precription has not changed.

 

Only concern is it may not be good for eye in long run due to eye can not get adeque relaxation during the night. So it is suggested that when the eye get matured after 20 years old, switch to other way of vision correction.
