Buying frames for your eyeglasses is not that complex. When you visit an optical store, you can discern its size just by putting them on. However, online buying works slightly differently. It would help if you were conscious of the frame dimensions to make a clear decision.
These dimensions include the frame width measurement of the whole horizontal front of the frame from the furthest extended point on either side. Next up, you must be aware of the lens height vertically and the bridge that lands on the nose.
Apart from this, the length of the glasses’ arms also determines its measurement because it must set behind your ears evenly, without falling or being uncomfortable. Lastly, you should measure the width of the lens in the horizontal diameter, which doctors also popularly called the “eye size.”
One of the most helpful tricks while buying frames is checking your existing eyeglasses and the numbers indicated on them. They are denoted on the temple arm and could have readings like 54-18-140. 54 is the width, 18mm being the bridge, and 140mm the temple arm.
How To Measure Frame Dimensions?
Some glasses may not have these numbers printed on them. In such cases, you can measure it yourself. Begin with the frame width. It is measured horizontally across the whole front of the frame. Do not forget to include any lug or hinge pieces that may stick out of the ends.
Next, measure the height of the lens vertically to target its highest point. For people buying frames bifocal or meant for progressive prescriptions, remember the height lens must be at least 30mm. Subsequently, measure the bridge horizontally and towards the two edges once you’re at the top of the bridge.
The temple arms are next in line. Begin by measuring the hinge where the arm intersects the front to the spot where the arms begin to curve towards the ears. Then measure from the top of the bend to the bottom tip. Sum up these two sections for the final total of the arm’s length.
Lastly, measure the lens horizontally at its widest point. It would be best if you ascertained that the lens width conforms to the pupil distance so appropriately align the eyes with the optical center of the lens.
How To Measure The Pupillary Distance?
1) Stand about 8ft away from a mirror and grab a ruler. Look straight into it and position the ruler above your nose.
2) Measure the distance between your pupils by starting with the right eye lined up at 0 and extending to the left eye. Jot down these measurements. To evade any fallacies, you could take multiple shots at measuring the distance. It’s possible to get them wrong initially, but you eventually get the hang of it. You could also ask a friend to help you because some people are afraid to hold objects close to their eyes. Remember to take these measurements before placing an order warily. A wrongly built frame can ruin the quality of vision and mar the overall experience for you.
Once you have measured the correct sizes to acquire your eyeglasses, you can make the final purchase. Remember to buy frames that suit your face because eyeglasses can define your look completely.
