When were eyeglasses invented?
It's hard to say exactly, but the earliest European portrait that includes them is of Hugh of Provence (above), painted by Tommaso da Modena in 1352.
Then as now, eyeglasses were a symbol of intellectual prowess. Even portraits of people who didn't actually wear them sometimes included a pair of glasses to emphasize their scholarly bent, such as this 1480 painting of St. Jerome by Domenico Ghirlandaio.
St. Jerome was best known for translating the Bible from Greek and Hebrew into Latin, which made it accessible to ordinary people of his time. Eyeglasses might have made this arduous task easier, but he couldn't have worn the glasses shown hanging from his desk. He died in 420, hundreds of years before they were invented! Still, so many painters depicted St. Jerome with eyeglasses that he became the patron saint of the guild of spectacle makers.

Just like clothes, eyewear has sizes, too!
One of the most common mistakes people make when buying eyeglasses online is ordering the wrong frame size. Similar to knowing the length and waist measurements of your pants size, finding the right eyeglasses size requires you to know a few different measurements, too. Our frame size guide below can help you determine the correct glasses size to order.
Keep in mind that your eyeglasses size and your sunglasses size may be slightly different, depending on the style of frames you choose for each. Also, each frame is different, so the size information you need may not always be located where you would expect.
If you have glasses already, your frame size is usually stamped somewhere on the frame--usually inside one of the temples.Other places you may look are along the nose pad, across the bridge, or sometimes on the ear piece.
What to look for:
There can be a variety of information inside your frame including the model number, the code to determine the color and style, the eye size, the bridge size, and the temple size. These can be displayed in varying orders and in a variety of ways, but don't get frustrated just yet. It's easier to find the information you're looking for than you may think!
You are looking for two sets of two-digit numbers and then one three-digit number. That's all you have to look for. Here's how to identify them:
A Two-digit number ranging from 40 to 62 = Your Eye Size
Another Two-digit number ranging from 14 to 24 = Your Bridge Size
A Three-digit number ranging from 120 to 150 = Your Temple Size
How to recognize the numbers you're looking for:
The eye size and bridge size are often located next to one another, sometimes separated by a square box icon (example shown above). The temple size may follow those two sets of numbers either immediately after or with other info in between.
What you can ignore:
If you see a group of capital letters and numbers together, this is generally the frame model number or the frame color/style number(s). In the image above, "VPR 020" is the frame model number while "EAJ-101" is the color/style number.
