PD must be paralel to DV, therefore  PD measurements must be committed throughtly. It requires comprehensive knowledge and technical skill. With the popularity of buying glasses online, a number of websites have come up with do-it-yourself measurements or apps that will take this measurement for you. The problem is that these are not scientifically accurate measurements and are not being performed by professionals.
