For some people, glasses are simply a means to see. But for others, they are an extension of their personality. Regardless of where you fall on the spectrum, there are a few keys to getting glasses that fit properly.

How they sit on your face, the dimensions of lenses and frames, and the frame’s style all contribute to how your glasses should fit. How glasses fit may seem unimportant, but poorly fitting glasses can cause visual problems, which we’ll explore below.

Unlike contact lenses, where you can get daily disposable lenses, eyeglasses are typically a long-term investment. So, the initial fit is essential, but knowing how or where to get your frames adjusted and repaired is also important. The experienced team at McCulley Optix Gallery can help adjust or repair your glasses or help you find your next pair

Measurements to Keep in Mind

Three common measurements you’ll see on frames are:

  • Lens width: The horizontal width of each lens at its widest point
  • Bridge width: The piece connecting each lens that spans your nose bridge
  • Temple length: The measurement from the hinge back to the end of the temple or arm

A significant benefit of purchasing your new frames from McCulley Optix Gallery is that they can assist with these measurements. 

At McCulley Optix Gallery, we make sure to:

  • Look at the bridge fit & width: Especially in plastic glasses frames, we determine the bridge fit over your nose. This can’t be adjusted, and gaps can cause your glasses to slide. 
  • Center your eyes horizontally with your lens.
  • Take your facial features into account, such as your eyebrows, cheekbones, etc.

How Should Glasses Fit My Face?

There isn’t a one-size-fits-all answer for how glasses should fit your face because our heads and faces are 100% unique. But there are a few certain areas to pay attention to when gauging how well a new pair of frames fit. 

Overall Comfort

Many people who wear glasses must do so at all times, so overall comfort is important. Wearing comfortable frames reduces the chances of getting sores and experiencing discomfort throughout the day. 

One thing to keep in mind regarding comfort is that you may notice over time that your glasses aren’t sitting how they did originally. Depending on the frame material and style, an optometrist or optician can usually adjust the frames for you.


Pupillary Distance (PD), sometimes called interpupillary distance, is the measurement between your pupils (the dark spots in the center of your eyes) while staring straight ahead. A correct PD measurement should put your pupils at the optical center of each lens.

An inaccurate PD measurement can cause uncomfortable symptoms, such as headaches or eye strain.


For long-term comfort, you’ll want to pay attention to how the frames sit on your nose. You want the weight to be distributed evenly while they rest on your nose.

They should be snug enough not to slip or slide easily. But the nosepiece shouldn’t be leaving indentations. Sometimes frames have adjustable nose pads, but others have fixed pieces that must fit as they are.

Temple / Arms

Another component of a comfortable fit will be the length of the arms or temple pieces of the frames. Too long or too short, and they may dig into your skin behind the ear and cause discomfort. The arms should squeeze just tight enough on the sides of your face to prevent the glasses from bumping and sliding around if you gently shake your head.

Finding a Proper Fit

If you already wear glasses that fit well, the measurements discussed above are likely stamped or etched into your frames. But if this is your first pair, your optician can help make sure you have the correct measurements to find the frames that fit the best.

A proper fit doesn’t necessarily only refer to comfort. Even if all the measurements are right, the particular style of the frames may not be right for your face. Sometimes, the frames simply need adjusting to sit properly, and other times a different shape entirely will suit your face better.

Importance of Properly Fitted Glasses

You may be wondering what the big deal is about glasses fitting properly. In reality, improperly fitting glasses shouldn’t cause any vision-threatening issues. But poorly fitting frames and an inaccurate prescription can lead to eye strain and headaches. Plus, they can take longer to adjust to as well.
