It worked
So I was trying to order some reading glasses online last month, and the seller was like "what's your PD?" and I sitting there like... what?? I had zero clue what that even meant. Did some googling and somehow ended up downloading this app. Honestly didn't expect much. But yo, it actually works. just follow the instructions, hold your phone up, and boom — it gives you your PD number in like few sec. Pretty straightforward, no complicated stuff. Gave the number to the seller, ordered my glasses, and when they showed up... they actually fit and I can see fine with them. I was lowkey shocked. Was fully expecting to waste my money.
