Will cylindrical power of the eye affect optic nerve?

Q: My seven years old daughter is using -2.75 cylindrical powers glasses for her both eyes. Is this the maximum power in children? Does it affect optic nerve? Does watching TV, playing video games and working on computer affect eye sight?

A:A cylindrical power of - 2.75 D does not affect the optic nerve in any way. As your daughter is still growing up, power may change. Therefore, regular eye check ups are important to determine the most accurate power and make sure she's wearing the right correction for her refractive error.

Computer work and TV don't really affect eye sight but its important to limit both these for a healthy lifestyle.
