It would be much easier for you, if I convert the prescription in a simple form.Right sph+0.25 cyl+1.75 axis 110 means +0.25 sph total defect with +1.75astigmatism. Left sph+0.25 cyl +1.50 axis 70 means +0.25 total defect with +1.50 astigatism.Astigmatism is due to difference in vertical and horizontal curvatures of the cornea.Your son is hyperopic(farsighted).It is for CONSTANT use, no excuse.
