If your prescription does not contain your PD: 1  Ask to have it measured at an optical shop â some may charge a fee. 2  Contact an optical shop where you have previously purchased prescription glasses. 3  Your previous optometrist may have a record of your PD.  Alternatively, try measuring your own Pupillary Distance as explained below.
Don't forget that if you are experiencing these symptoms you need to make an appointment with your eye specialist and have a full eye exam. Your optometrist or ophthalmologist will conduct a number of tests that will get to the bottom of your eye problems, and if you need glasses they will write you out a prescription.
