There are websites with instructions. Basically you hold a ruler with metric markings across your forehead just above your eyes, stare into your webcam at reading distance, and take a photo. Then you do the same as you stare off in the distance. The distance between the center of your pupils in mm are your reading and distance PD values. Note that I am not an optical professional so don’t take my word or advice as medical advice. </div><div dir="auto"><br></div><div dir="auto">Cheers,</div><div dir="auto">-steve </div><div dir="auto"><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, May 14, 2023 at 1:39 PM S Ou <<a href="mailto:shukong@gmail.com">shukong@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Steve, <div>I've just recently had my eyes checked and got a new prescription.

Even if you got a set to verify your diopter, other issues like astigmatism and other adjustments might be better left to people who went to school for this. But if there is a kit that does measure all these parameters, that would be cool. The basic elements of a prescription are explained here <a href="https://www.perfect-eyeglasses-guide.com/eyeglass-prescription.html" target="_blank">https://www.perfect-eyeglasses-guide.com/eyeglass-prescription.html</a> </div><div><br></div><div>The final straw is this: when you order online, for example at <a href="https://www.zennioptical.com/" target="_blank">https://www.zennioptical.com/</a> or <a href="https://www.39dollarglasses.com/" target="_blank">https://www.39dollarglasses.com/</a> part of the ordering process is to upload a photo of your prescription. By the way, there is a measurement for inter pupillary distance (P.D.?) that you might have to request from your optometrist and might be different from left to right eye (sometimes they don't get written down).</div><div><br></div><div>I am now a firm believer that a good eye doctor who has past years records and images of your retina is a valuable baseline to have. Plug here for Winchester Optical (Main St, WInchester) - Dr Deering is thorough and caring.<br></div><div><br></div><div>Best of luck -- I strongly support doing things for ourselves whenever, but your eyes are very important.</div><div>If you do get a set, that would make a great talk! In-person double check of your prescription. </div><div><br></div><div><br></div></div><br><div class="gmail_quote"></div><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, May 14, 2023 at 11:14 AM Steve Isenberg <<a href="mailto:smisenberg@gmail.com" target="_blank">smisenberg@gmail.com</a>> wrote:<br></div></div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"></blockquote></div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Gentlepeople,<div dir="auto">I’m thinking of getting a optometrist lens set so I can measure my vision and fine tune my eyeglass prescription. </div><div dir="auto">I’m thinking of the old type, where you wear a frame and the doc inserts different lenses, asking is A or B better, etc. </div><div dir="auto"><br></div><div dir="auto">Any thoughts on what I’m thinking?</div><div dir="auto">Do you know of a lens set I could get for free or low price?</div><div dir="auto">Have you done or considered doing anything like this yourself?</div><div dir="auto"><br></div><div dir="auto">Thanks,</div><div dir="auto">-steve </div></blockquote></div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
