Thanks for the query..
These look like AR readings to me..( AR - Auto refractometer
- a machine used to see the refractive error
These values are approximate. Whether you really require glasses or not depends on subjective refraction
The values you mentioned show that you have a very less cylinder power in both eyes. But if your VA is 6/6 (20/20) without glasses and you are not accepting any cylinder by subjective method, you don't have any refractive error and you don't have to use glasses..
Don't bother about the values..
Hope i helped with my answer..
