My son, who is seven years old, was recently found to have -3.25 D cylindrical power for both eyes (with 6/6p) vision. Is having such high power at this young age dangerous? Will the power increase with age? The doctor has prescribed glasses for him and said to follow up in six months. He also checked and confirmed that there was no other problem in his eyes. What are the different treatment options available for him?
Having cylindrical power is called astigmatism. It is not dangerous. It may or may not increase with age. I suggest continuing glasses for now. Does he have allergies? Does he keep rubbing his eye? Get his corneal topography done to rule out keratoconus. Regular follow-ups should be done. A good diet including green leafy vegetables and yellow-orange colored fruits and vegetables should be taken.
Thank you for the reply.
My doctor has checked his eyes and confirmed that he has had no other disease or condition till now. But my concern is that with glass, why is his vision partial 6/6 and full 6/6 (with glasses)? Is it normal? As he has not worn glasses till now. Will his vision improve upon regular use of glasses and reach full 6/6 with glasses?
I understand your concern. Firstly astigmatism is a refractive error where you have decreased vision in only one axis. Hence he has a good vision of 6/6 partial. But his clarity of vision may need improvement due to astigmatism. It will improve with the regular use of glasses. And yes, it may reach full 6/6 with glasses. Also, his eye is growing, so his power will change with time.

Same symptoms doesn’t mean you have the same problem. Consult a doctor now!
.. not mentioned how much astigmatism you got. If it is negligible, then it will be fine with the spherical lens only. If it is significantly high, then you must need toric lenses. You can get a customized contact lens from some good optician or lens disp Read full
.. has an astigmatism and that too upto 2.5 diopter, it is rare that it is reversed. But sometimes optometrist can add astigmatic power in spherical power that is called spherical equivalent. In such cases half the power of cylinder is added to spherical Read full
