Sir, Good Morning. My daughter is 9 years old. Due to rubbing of left eye, cornea has become light steep (thin) and she got -4.0 / 180 Degrees / +0.50 power for left eye. And the right eye is Normal. After wearing the spectacles, many times she is able to see normal with the left eye. But sometimes in the classroom, her vision is blur. We could not understand the problem. Will the left eye cornea will become normal while she grows ? Is there any chance of cornea becomes more steeper without doing anything also. Is there any problem with -4.0 power to left eye only? Please give me suggestions and exercises to become cornea normal. Thank You Very Much. Regards, Ravi
