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.
If your symptoms include the following, you may want to return to the optometrist for advice or at least a confirmation that no clerical error in your prescription was made: 1  Extreme blurriness or lack of focus. 2  Poor vision in only one eye when the other is closed. 3  Headaches or dizziness caused by excessive eye strain.
