There are a lot of things to be said for ordering glasses for your child online: they’re generally less expensive for one, and some online retailers have a better selection of children’s frames. Make sure that you take any glasses (ordered online, or in a store) to have the prescription tested to be sure that it is accurate. While glasses ordered through a traditional shop have a similar rate of errors, those errors are much more likely to be caught and fixed by an optical shop.

Measuring your pupillary distance is a snap using EyeQue’s PDCheck!ĮyeQue offers PDCheck which is a pair of patented frames that you can use with a pupillary distance app so that you can measure your PD quickly and accurately. Normally, this condition is only corrected for aesthetic reasons. If you have a pupillary distance which is longer than normal, you may have a condition called hypertelorism(also known as hypertelorbitism). Examples of binocular cues include tilting your head forward, looking over your shoulder, and your glasses’ or sports goggles’ response to your PD.Īccording to the American Academy of Ophthalmology, the average pupillary distance measures between 60 to 62 millimeters. Studies have shown that changes in “binocular cues” directly impact your depth perception and athletic performance. You probably won’t be surprised to learn athletes rely heavily on their vision to be successful in sports, as many sports require accurate depth perception.
How Does PD Affect My Performance in Sports? You will notice that your focus is off and that glasses just don’t fit right.
This can cause headaches and excessive eye strain.
If eyeglasses are not properly fitted according to the PD measurement, the patient may experience something called “induced prism,” meaning the lenses will not focus light properly to the eyes. Moreover, the American Optometric Association emphasizes that patients with myopia should be especially mindful of their PD. Eyeglasses lenses are curved based on your prescription. Your PD measurement helps the eyeglasses manufacturer to align your prescription properly to your eyes. If you look at your eyeglasses, you’ll notice the lenses are not flat-they curve slightly so your prescription will work properly. The Mayo Clinic explains that it is needed to create your eyeglasses. Have you ever heard your eye doctor use the term “pupillary distance” during an eye exam? Pupillary distance is also known as a PD or interpupillary distance, and the term refers to the distance between the pupils of your eyes.
