How to know my glasses size

Have you ever bought glasses that are too tight or slip off? It's because they are not your size. Frames are made with specific measurements regarding lens length, bridge width and temple length.

Choosing the ideal frame for your face goes beyond features, style and fashion. You also have to pay attention to your size to feel comfortable and confident with your glasses .

At Óptica Bassol we explain to you step by step how to recognize your size of prescription glasses and sunglasses . There are techniques and tricks to make this task simple and easy. Keep reading and wear your glasses comfortably!

How do I know what size glasses I have?

If you are going to buy your glasses online or simply want to know your glasses size, You just need to follow a few steps. There are also tricks that allow us to know our size. Let's look at some of them:

1. Measure with credit or debit card

Credit or debit cards have a standard size, so we can use it as a reference point to determine our size.

Place the card vertically next to your nose, at the level of the bridge of your glasses. Note how far the credit card extends below your eye. If the edge of the card extends past the edge of your eye, you are a size S.

If the edge of the card ends at exactly the same distance as your eye, you are a size M. Finally, if the card does not cover your eye, it means you are a size L.

You can do this trick in case you cannot go to an optometrist , since it is advisable to go to a professional.

2. Inscriptions on the glasses

Glasses have their measurements written on the inside of the temples. If you previously had glasses, whether sunglasses or prescription, it is easier to check these measurements and identify your size.

When you look at the inside of the temple, you'll find a series of numbers like: 50-18-144. To find out what size this refers to , you need to locate the standard measurements for lens length, bridge width, and temple length. They are always printed in that order.

3. Consult a size guide

There are specific size guides such as those offered by eyewear brands like Ray-Ban that explain how to find your exact size using your current frame as a reference point.

Does the size vary depending on the type of glasses and my features?

This is a constant question when buying a new frame. If we have sunglasses and need prescription glasses or vice versa, we can be guided by the measurements of the previous glasses. The sizes of sunglasses and prescription glasses are the same .

On the other hand, it is true that it is important to take into account our features when choosing the frame for our glasses. However, this does not influence the size. For example, there is no special size for prescription glasses for a large nose .

You can choose the frame by following some tips that will help you soften this feature. Some models that go well with a large nose are: Lindberg 6640 C04 804 PU14 45 and Oliver Peoples OV5547U N.05 1741 48 .

Tips for choosing the right glasses size

Take the following points into consideration when choosing your glasses size:

• Comfortable fit : glasses are an everyday item, especially if they are prescription glasses. That's why comfort is a priority when choosing your glasses.
  If your glasses leave marks on your nose or behind your ears, they are definitely too small for you. If, on the other hand, you feel like you can't look at the ground because they slip, then they are too big. Glasses should fit so that you can comfortably turn your face, bend over and walk with confidence.

• Proper proportion : Lenses should be centered in front of your eyes and should not be wider than your face.

Once you know the correct size of your glasses, you can choose the model based on aesthetic criteria, such as the color of the glasses according to your hair , the shape of your face and the tone of your skin. Your look will enhance your natural beauty by choosing the ideal size and color in trendy models such as the Miu Miu MU 01ZS 1AB5S0 55 or the Prada PR 65ZS ZVN09T 55 .

What sizes of glasses are there?

As we explained before, glasses are similar to clothing. They are classified in sizes S (small), M (medium) and L (large) . To know which sunglasses are for small , medium and large faces, it is important to know which parts of the frame are taken into account in the measurement:

• Lens length : This measurement refers to the horizontal distance from the left edge of the lens to the right edge. Standard measurements range from 50mm to 60mm. However, this can vary slightly depending on the style and shape of the frame.
• Bridge width : This measurement is very important because it determines whether or not the lenses fit your face. To identify it, you must measure the closest edges of the lens. This measurement ranges from 14 mm to 24 mm. A bridge that is too short will squeeze your nose, if it is too wide it will slip.
• Temple length : This measurement refers to the length of the temples, which is the part that fits behind the ear. This measurement is taken by measuring from the end of the temple to the point where it connects to the frame. The standard temple length ranges between 120mm and 140mm.

In the case of children, sizes are determined the same , but standard measurements are between 4 mm and 10 mm smaller:

• Lens length: In children, they range between 40 mm and 50 mm.
• Bridge Width: The distance between lenses ranges from 14mm to 18mm.
• Length of the rods: The length of the rods ranges from 110 mm to 130 mm.

What measurements go with what size?

After identifying the parts of the glasses considered for the sizes, we share with you the measurements of each size:

• Small (S) : approximately 40-44mm lens diameter, 14-16mm bridge width, and 120-130mm temple length.
• Medium (M) : Approximately 45-48mm lens diameter, 16-18mm bridge width, and 130-135mm temple length.
• Large (L) : about 49-50mm lens diameter, 18mm bridge width and 135-140mm temple length.
