A Guide To On Measuring Your Rx Safety Glasses Size

If you’re on the lookout to buy your next pair of protective eyeglasses online, chances are that you may have been overwhelmed by the idea of getting a perfect size that fits your face. Online shopping for glasses requires careful knowledge beforehand of the dimensions of your face because that is the only thing you’ll be entering when placing your order on a website as opposed to a brick and mortar store. If you bought your old glasses quite a while ago such that you’ve completely forgotten what are your measurements, read on to know about a few simple things that will get you started on buying prescription safety glasses online.

Knowing Measurements with Your Own Frames

There are three core measurements when it comes to measuring any eyewear. These are lens diameter (which involves measuring both the lens width & height), bridge width & arm length. The same format applies when buying any other regular prescription glasses or your go-to protective eyeglasses. This guide will help you ascertain your own facial measurements with your personal eyeglasses. To get you started, here are a few steps to follow in order to gauge your current frame size:




  1. To measure lens diameter, fold the arms or temples of your eyewear and lay the frame flat with the lenses facing up. Make sure you the surface is flat enough to provide a smooth measurement. Then use the same ruler or tape to measure its height. Make sure that you properly get these right as they will form the basis for the rest of the calculations that follow.

  2. Grab a measuring tape or a ruler that has millimeters marked on it. Place the chosen device on the lens surface and take a reading from left to right across the face of the lens. Note down the measurements.

  3. Next up is the bridge width which is needed to be estimated from the inside of your right lens to the farthest inside part of your left lens. This distance is important as different people have various nose shapes which call for a careful assessment of how the frame will actually sit on your nose. For instance, a narrow bridge can cause headaches or spectacle marks on your nose which can very discomforting & bothersome.

  4. Finally, finding out arm's length requires measuring temple tips right from the bottom up to the end that connects with the frame at the hinges. Speaking of temple tips, you should always pay attention to how comfortable they make you feel. For example, Wiley X Safety Glasses come with rubberized temple tips that provide a non-slip grip to let your glasses stay perched on your face no matter regardless of any high volume sports or activity you’re involved in.

  5. Lastly, the frame width is important in getting the perfect fit. For instance, a frame that is too narrow for your face will give a wider appearance and vice versa. To do this, start measuring from one end of the frame to the other. Note:- You should be taking all measurements in millimeters.

When done with all of these, you would also need a PD or pupillary distance. This is the amount of distance between the center of your pupils from one to the other. You can have a friend do it for you with the help of a measuring strip that is attachable to your forehead. You can even download one from eyeweb.com to get your first pair of branded eyewear such as 3M Safety Glasses. On the whole, if you get all the measurements right, you’re officially ready to get a high-quality frame that provides the best of visual acuity & safety assurance for your eyes.
