[dhcprasad]

Respected sir,
         I am 23 years old and I got my eye checkup recently. It Showed that Cylindrical sight 0.5 at 180 degrees for both the eyes. So I would like  to ask you following few questions.
1. What are cylinderical and sperical sights.
2.What is the importance of axis here. Is that ok if my spectacles axis is  deviated from 180(My prevoius spectacles are showing 165 and 175 dgree axis. )
3.Few precautions to reduce my eye sight if not possible not to agrevate it regarding food, lifestyle, correct use of spectacles etc.

                                        Thank you in advance.

It just means your cornea is slightly aspherical. That's not unusal and the amount is very small. You can use the search feature and archives and read about what the various parts of a glasses prescription mean.

To keep you eyes healthy don't smoke, exercise ideally about 20-30 minutes/day, don't get obese, eat a good diet, protect your eyes from bright sunlight with hate with bill and sunglasses.
