Step 5. Use these measurements to determine your face shape

This is an important step in deciding which structures are best for you. While the fit is most important, it's also crucial to make sure the style suits your face. Ideally, glasses should balance the natural proportions of your face.

Although faces come in all shapes and sizes, most of them can be classified as square, triangular, oblong, rounded or oval. Oval faces match any frame shape and style

Step 1. Use the current frame as a reference

This size is usually found on the inside of the rod or bridge, depending on the manufacturer. Lens size usually comes first, accompanied by bridge size and shank size. Lens size is most often used to define the best frame size.

  • You have a three millimeter margin on each measurement, except for the bridge. In it, stick to a margin of just two millimeters.
  • The frame width will not be printed on it. Follow the guide below to accurately measure this value and ensure a perfect fit.

Step 2. Take your own measurements with old glasses

Don't worry if the numbers aren't printed on the frame. You can always use a ruler or measuring tape. To begin, measure the frame width horizontally across the front, remembering to include any screws or joints that protrude. Next, measure the rods from the joints to the point where they bend over the ears. After that, go from the top of the fold to the bottom edge. Add the two measurements together for the total length of the rods.

  • The height of the lenses is measured vertically at the highest point of one of them.
  • The bridge is measured horizontally across the top of the bridge, running from one lens edge to the other.

Step 3. Use a credit card to measure your face

If you're in a hurry and can't find a ruler or measuring tape, you can use a credit card. Although lens sizes vary by brand, most credit cards are about the width of a standard lens. Using a mirror, take a credit card in one hand and hold the edge of the bridge against your nose and under your eyebrow. Notice where the other edge ends.

  • If the edge of the card is aligned with the edge of the eye, you'll feel comfortable using a standard size.
  • If the card advances beyond the edge of the eye, it may be helpful to consider a smaller size.
  • On the other hand, if the card doesn't reach the edge of the eye, it's better to opt for a larger size.

Step 4. Make sure the frame material is compatible with the purpose

There are many different options to choose from depending on your needs. Plastic and metal are the most common materials. There's even nylon or titanium if you need a lighter or hypoallergenic option.

  • Nylon is often used in athletic or athletic frames.
  • Although generally the cheapest option, plastic frames break more easily than steel or metal ones.

Step 5. Choose lens material wisely

As well as the frame material, there is a wide range of lenses to choose from. Plastic or polycarbonate ones, in general, are the cheapest. However, a lens with a higher plastic index will be thinner and lighter than a polycarbonate lens.

  • Polycarbonate is the softest lens material and also the most impact resistant.
  • You must ensure that the lenses will protect your eyes from harmful ultraviolet radiation. The good news is that polycarbonate lenses and other high-index materials come with 100% UV protection included.
