![]() However, if you’re cool with average, here’s the average PD’s for adult men and women.Are you planning to buy new prescription glasses online? In order to spend your money wisely and not to suffer from ailments related to wearing mismatched lenses, you first need to know your pupil distance (PD). You’re better taking a few minutes to get a proper measurement using our advice above. If you wear single vision glasses, it can be okay to use average PD’s. For example, your right eye Mono PD could be 32.5mm and your left eye could be 33mm. Your mono PD’s will vary ever so slightly. In fact, the most attractive celebrities have facial asymmetry… phew. You can measure your mono PD yourself with a basic ruler, but we suggest you use our free PD ruler which locates onto the centre of your nose for a more accurate result.ĭon’t worry, most people have a slightly asymmetrical head. Generally, total PD’s or average PD’s are considered as insufficient for varifocal prescriptions. Varifocal glasses have a higher tolerance of accuracy as they are a more complex lens type. This lets us that your lens centres are as accurate to the centre of your pupil as possible. However, if you require complex or strong prescription lenses such as varifocals, it’s imperitive that you provide your dual PD's as per each of your eyes. This is usually for single vision glasses wearers. These can be added together, but only if require a PD total. Your prescription paper may use dual PD’s as standard. Dual PD = the separate distances between the centre of your head and the centre of your pupils.Single PD = the total distance between the centre of your pupils.Mentioned earlier, your PD can be written as one or two numbers. What is single PD and dual PD when ordering glasses? Heck, with the instructions above, you know what you’re doing. Your glasses can sit ever slightly ‘off’ on your face so pin-point accuracy is perhaps a little bit overkill. Sure, you don’t want to give us the wrong pupillary distance… but think about it. ![]() It’s safe to say that guessing your PD is a big no no, especially after reading the steps we’ve shown you above.īut let’s not freak out about this one guys.
