How to Find Your Perfect Glasses Size & Style | Payne Glasses Guide

1. How Do You Know Your Size

If you have already had a pair of glasses or sunglasses, measure the frame width, the horizontal length from one side to the other, in millimeters.

Alternatively, check for numbers on the temple arm of your glasses, such as "54 □ 19-147," where "54" is the lens width, "19" is the bridge width, and "147" is the temple length.

If you don't have existing glasses, stand in front of a mirror and measure the distance between your temples (right at the tops of your ears) with a ruler or measuring tape. Then convert inches to millimeters by multiplying by 25.4. When browsing frames on our site, you can use the "Filter" option to select frame width ranges that match your measurement. A range within two millimeters is usually comfortable. This will help you find the right size for a comfortable fit.

2. How To Find the Best Frame For Your Face Shape

Wondering who can pull off cat-eye or rectangular glasses? What face shapes suit your favorite frames best? You can choose your frame based on your face type. For example, if you have a narrower forehead & a gently curved jawline, a slightly longer face than width, a defined chin, and high cheekbones, then you have an oval face.

For Oval Face Shape

Rectangle, cat-eye, round, and square would be your best choice.

If you're not sure about your face type, take a quiz! For more Face Shapes, check here.

You can also make a decision based on different Frame Styles, Frame Shapes, Frame Color, and Frame Material.

3. How Do You Know If a Frame Looks Good on You?

We recommend using our Virtual Try-On tool or other resources to find the best fit before purchasing.

4. How Do You Know If You Need Glasses or Not?

There are some common signs you may need glasses:

Vision clarity:

  • Blurry vision at distance (street signs, TV, driving) → often nearsightedness
  • Blurry vision up close (reading, phone, menus), especially after ~40 → often presbyopia (reading glasses)

Strain symptoms:

  • Frequent headaches (especially after reading/computer work)
  • Eye strain, tired or "heavy" eyes
  • Squinting to see clearly (squinting can temporarily sharpen focus)

Comfort + function:

  • Difficulty seeing at night or increased glare/halos around lights
  • You need brighter light to read than you used to
  • You lose your place while reading or avoid reading because it feels uncomfortable
  • You sit very close to screens or the TV

Other clues:

  • One eye seems noticeably blurrier than the other
  • You're tilting your head or closing one eye to see better

Practical next step

If you answer "yes" to any two of these, schedule an eye exam:

  • I squint to see clearly
  • I get frequent eye strain/headaches
  • Night glare/halos bother me
  • One eye is clearly worse
  • Near or distance blur affects daily tasks

Go to your optometrist and get your prescription. We'll help you to read your prescription.

If you do not have any of these problems, dry eye, allergies, fatigue, migraines, or screen overuse can mimic prescription problems. Glasses can still help!

For example, if your goal is to reduce digital eye strain (tired eyes, headaches at the computer), blue light-blocking glasses can reduce short-term eye strain compared with regular lenses. Or you use screens late and struggle to fall asleep, since Blue light can affect circadian timing/melatonin. A pair of Blue Light Blocking glasses is exactly what you need. Indoors or outdoors, blue light-blocking lenses go beyond UV protection, filtering out harmful blue-violet light for enhanced visual comfort and eye protection.

7. How to Choose Sunglasses Lenses From So Many Options?

Firstly, check this out: this is a complete guide to the most popular sunglasses lens options and how they enhance both comfort and style.

Choosing the best sunglasses lenses depends on your lifestyle, light sensitivity, and how you plan to wear your glasses.

Solid Tint Lenses

If you want reliable everyday sun protection, solid tint lenses are a classic choice. Lighter 40% fashion tints work well for cloudy days or casual wear, while 85% classic tints offer stronger protection for bright outdoor conditions.

FL-41 Lenses

If you deal with migraines, light sensitivity, or long hours of screen use, FL-41 lenses are a smart option. Their soft rose tint is designed to help reduce eye strain and improve visual comfort indoors or outdoors, depending on the tint level you choose.

Gradient Lenses

For a versatile look, gradient sunglasses lenses are darker at the top and lighter at the bottom. This makes them a great choice for activities like reading at the beach or moving between bright outdoor light and close-up tasks, because they offer both sun protection and easier downward vision.

Mirrored Lenses

If you spend time in especially bright conditions, mirrored lenses can help reduce glare, limit light transmission, and sharpen visual clarity. They also add a stylish, fashion-forward finish. For even more performance, polarized mirrored lenses combine mirror coating with polarization for added glare control.

Polarized Lenses

For driving, boating, cycling, skating, or time around water, roads, or snow, polarized sunglasses lenses are one of the best options. They are designed to reduce harsh reflected glare, improve contrast, and make outdoor vision more comfortable.

Photochromic Lenses

If you want one pair that can adapt throughout the day, photochromic or light-responsive lenses are worth considering. These lenses stay clear indoors and darken in sunlight, making them a convenient choice for people who frequently move between indoor and outdoor environments.

Quick Summary

In short: choose solid tints for everyday wear, FL-41 lenses for light sensitivity, gradient lenses for versatility, mirrored lenses for bright conditions, polarized lenses for glare reduction, and light-responsive lenses for all-day convenience.
