You need to visit on optometrist or ophthalmologist for an eye examination.





If you are myopic they will reduce the sphyrical value in your prescription according the the reading addition you require e.g +2.00 will give your R -4.00 and L -3.50.





If you wear contact lens they will simply prescribe off the peg readers to wear over your lenses.
