Finding the Perfect Fit: Understanding Eyeglass Frame Sizes

When it comes to purchasing new prescription eyeglasses, one of the most fun and exciting parts is choosing the perfect pair of frames. After all, the frames are the first thing others notice when they see you and they also make up the base for the rest of your prescription eyeglasses. And while it’s easy to get caught up in looking for a pair of stylish designer frames in the right color and shape, we often overlook one crucial aspect - the frame size.

When considering whether a pair of eyeglass frames will suit your unique face shape and enhance your look, don’t overlook the importance of frame size. An often forgotten step in the process of choosing prescription eyeglass frames, the size of your eyeglass frames can make all of the difference in what they end up looking like when you finally receive them and get to slip them on. In addition, the size of your eyeglass frames should also correlate with your prescription lenses to ensure that they can support the lenses’ size and weight.

If you’re considering purchasing a new pair of designer prescription eyeglasses and finding that you are a little confused about where to start when considering frame size, we’re here to help. Keep reading to discover how to find the perfect frame size to fit your unique face shape and the needs of your prescription lenses.

Considering Your Unique Face Shape

When thinking about the importance of the size of frames, often the first thing that comes to mind is your unique face shape and silhouette. You can shop all you want for the right shape of frames to flatter your face shape, but if you choose the wrong size, they can end up being unflattering when you finally receive them.

For example, if you have a larger round face and have selected a pair of square frames to complement it, they can quickly become unflattering and uncomfortable if the frames themselves are smaller than the width of your face. On the other hand, if you have a smaller round face and choose a pair of oversized square frames, they can become overwhelming and weigh down the face. Look for a happy medium when choosing a pair of designer prescription frames that complement your unique face shape and size.

In addition to being unflattering, the wrong size of prescription eyeglass frames can quickly become uncomfortable to wear. If you have a thinner face and have chosen a pair of heavy, oversized frames, they may not sit properly on the face and can potentially cause slippage or fatigue when worn for long periods. The same is true on the opposite end of the spectrum - if you have opted for a pair of smaller frames but have a wider face, this can cause stretching and loosening of the hinges, resulting in looser wear that is uncomfortable and has the tendency to slip.

Some people may benefit from low nose bridge style of glasses. Low nose bridge fit eyeglasses are designed to accommodate individuals who have a lower or flatter nose bridge. People with this facial feature often find it challenging to wear standard eyeglasses because the frames may slip down their noses or cause discomfort. 

Considering Your Unique Prescription Lens Needs

Now that we’ve covered your appearance and comfort while wearing your designer prescription eyeglasses, it’s time to talk about the prescription lenses themselves. For those among us who have a stronger corrective prescription, whether it’s near-sightedness or farsightedness, we need to consider the size of our frames concerning how heavy or bulky the lenses will end up being.

If you have a very high prescription and therefore a thicker prescription lens, choosing a pair of smaller eyeglass frames can be limiting. You may find that although your prescription lenses can fit, they’ll feel heavy and uncomfortable on the face. In addition, the lenses themselves may extend past the frames, causing further discomfort. With stronger prescriptions, it’s important to choose a pair of larger frames that can both support your prescription lenses and fit comfortably on the face.

However, with modern innovations such as high-index lenses, those of us with higher prescriptions are no longer as limited in frame choices as we were in the recent past. With these thinner and lighter lens options, you can choose a wide variety of frame styles and sizes, no matter how high your prescription is. If you’re leaning towards a smaller frame size, take a look at the lens options available and choose high-index if possible for the best fit and most comfortable wear.


Always remember, when it comes to picking out the perfect pair of designer prescription eyeglass frames, don’t forget to take a closer look at the frame size. The size of the frames plays an important role in how the glasses will look on the face and also how well your unique prescription lenses will be supported. By choosing the perfect pair of frames that are flattering in both size and shape and can also support your lenses, you’ll be well on your way to seeing clearly and stylishly.
