How to Choose the Perfect Pair of Glasses: A Simple Guide

Your glasses should help you see better—and make you look pretty great doing it.

Choosing a new pair of glasses can be surprisingly difficult.

There are thousands of frames, endless colours, different lens options, different materials, and approximately 47 million opinions about which glasses “suit your face.”

So where do you even start?

The good news is that finding the right pair doesn't have to be complicated.

The perfect glasses are really about finding the sweet spot between fit, comfort, function, and style.

In this guide, we'll walk you through everything you need to consider when shopping for glasses—from your face shape and frame size to lens options and the little details that can make a surprisingly big difference.

And yes, we'll also talk about keeping those beautiful new lenses clean.

Because finding the perfect glasses only to cover them in fingerprints five minutes later would be a bit of a shame.

1. Start With the Right Fit

Before you worry about colour, shape, or whether you look better in tortoiseshell or black, make sure the glasses actually fit your face.

A great-looking pair isn't going to feel very great if it's constantly sliding down your nose.

When trying on glasses, look for a few things:

They shouldn't slide down your nose

Your glasses should sit comfortably without constantly needing a little push back up.

They shouldn't pinch

Pay attention to the sides of your head and behind your ears.

If the frames feel tight after a minute or two, imagine how they'll feel after wearing them all day.

Your eyes should sit comfortably within the lenses

Ideally, your pupils should sit reasonably close to the optical centre of the lenses.

This is particularly important for prescription eyewear.

Your frames shouldn't move around excessively

Try smiling, talking, looking down and moving your head.

If your glasses immediately start heading south, they're probably not the right fit.

2. Know Your Frame Size

You may have noticed a series of numbers printed on the inside of your glasses.

Something like: 52 □ 18 □ 140

Those numbers aren't random. They generally represent:

52 mm — lens width
18 mm — bridge width
140 mm — temple arm length

Together, these measurements give you an idea of the overall size of the frame.

If you already own a pair of glasses that fits really well, check the numbers printed inside the frame.

They can be a useful starting point when shopping for your next pair.

Just remember: numbers aren't everything.

Two frames with identical measurements can still feel completely different depending on their shape and construction.

3. What Glasses Look Best With Your Face Shape?

Here's where things get fun. You've probably heard that certain frames are “best” for certain face shapes.

There's some useful guidance here—but don't treat it like a set of laws carved into an optical stone tablet.

If you love a pair of glasses, wear them.

That said, face shape can be a helpful starting point when you're not sure where to begin.

Round Face

Round faces typically have softer angles and a similar width and length.

Try frames with:

More angular shapes
Rectangular frames
Square frames
Stronger lines

These can add a little contrast to softer facial features.

Square Face

Square faces tend to have a stronger jawline and more defined angles.

Oval Face

Lucky you. Oval faces tend to work well with a wide range of frame shapes.

You can experiment with:

Round
Square
Rectangle
Cat-eye
Geometric frames

Just pay attention to proportion so the frame doesn't overwhelm your face.

Heart-Shaped Face

Heart-shaped faces are often wider around the forehead and narrower toward the chin.

Frames that can work well include:

Rounded shapes
Light or thin frames
Bottom-heavy styles
Cat-eye frames

The goal is often to create balance between the upper and lower parts of the face.

Oblong or Long Face

If your face is longer than it is wide, you may want to try frames that add a little visual width.

Consider:

Larger frames
Taller lenses
Stronger bridge details
More decorative temples

Again, these are suggestions—not rules. The best frame is the one you actually feel good wearing.

4. Think About Your Personal Style

Your glasses are sitting right in the middle of your face.

They're not exactly a background accessory.

So think about what you want them to say.

Want something classic?

Black, tortoiseshell, brown and understated metal frames are timeless choices.

Want something modern?

Try geometric shapes, transparent frames or thinner metal designs.

Want something playful?

Go for colour.

Your glasses can absolutely be part of your personality.

Want something that disappears?

Look for lightweight, neutral or thin frames that blend more naturally with your features.

Want something that gets noticed?

Go bold. Bright colours, oversized shapes and distinctive frames can turn your glasses into one of the best parts of your outfit. There isn't a “correct” answer here.

Your glasses don't have to match everyone else's.

They have to match you.

5. Choose a Frame Colour You Actually Love

Colour can completely change how a pair of glasses looks on you.

You might naturally gravitate toward colours that complement your hair, eyes or skin tone.

But here's our advice:

Try them on.

A colour that looks ordinary sitting on a website can look fantastic once it's actually on your face.

And don't automatically rule out a colour because you've never worn it before.

Sometimes the pair you almost didn't try becomes the pair you can't stop wearing.

6. Consider How You'll Actually Use Your Glasses

This one gets overlooked.

Your perfect everyday glasses might not be your perfect pair for every situation.

Think about your lifestyle.

Working at a computer?

You may want to discuss lens options designed for your prescription and visual needs with your optician.

Driving a lot?

Consider your prescription, lens design and whether glare or reflections are an issue for you.

Spending lots of time outdoors?

Prescription sunglasses can be a great option.

Very active?

You may want lightweight, durable frames that stay securely in place.

Wearing glasses all day?

Comfort should be near the top of your list.

Because the coolest pair of glasses in the world isn't much use if you can't wait to take them off.

7. Don't Forget Your Prescription

Style matters. But these are still prescription glasses. Before ordering, make sure your prescription is current and that you understand what you're buying.

Your prescription may include measurements and information such as:

Sphere (SPH)
Cylinder (CYL)
Axis
Add
Prism
PD (pupillary distance)

Not every prescription includes every measurement.

If you're ordering glasses online, make sure you enter your prescription exactly as provided.

And if you're unsure what something means? Ask your optometrist, optician or the eyewear retailer.

It's much better to ask a question than guess.

8. Don't Forget Your PD

Speaking of measurements...

Your PD, or pupillary distance, is another important measurement when ordering prescription glasses.

PD is the distance between the centres of your pupils, measured in millimetres.

Depending on the retailer or prescription, you may need either:

A single PD: 62 mm

or a dual PD: 31 / 31 mm

or something like: 32 / 30 mm

If you don't know your PD, don't worry.

You can often measure it yourself at home with a millimetre ruler and a mirror.

We put together a complete guide here:

9. Pay Attention to the Bridge

The bridge is the part of the frame that sits across your nose.

And it can make a surprisingly big difference to how comfortable your glasses feel.

If the bridge is too wide, your glasses may slide down.

Too narrow, and they may pinch.

Some frames have adjustable nose pads, while others have a fixed bridge built directly into the frame.

If you're shopping online, look at the frame measurements and compare them with a pair you already know fits well.

10. Think About Lens Materials

Your frame isn't the only thing you get to choose.

Your lenses can come in different materials and designs depending on your prescription and needs.

Your optician can help you determine which option makes sense for you.

You may encounter options such as:

Standard plastic lenses
Polycarbonate lenses
High-index lenses
Progressive lenses
Photochromic lenses
Polarized lenses for sunglasses

The best choice depends on your prescription, lifestyle, budget and preferences.

Don't feel like you need to figure all of this out yourself.

That's exactly what your optical professional is there for.

11. Consider Lens Coatings

Modern lenses can have a variety of coatings designed to improve performance and durability.

Depending on your lenses, you may encounter:

Anti-reflective coatings

These can help reduce reflections on the lens surface.

Scratch-resistant coatings

These are designed to improve resistance to everyday scratching—but no lens is completely scratch-proof.

UV protection

UV protection can help protect your eyes from ultraviolet radiation.

Blue-light filtering

Some lenses offer blue-light filtering features.

Whether you need a particular coating depends on your eyes, lifestyle and preferences.

Your optician can help you decide which options are worthwhile for you.

12. Try Before You Buy When You Can

If possible, try frames on before committing.

Look at yourself from the front and side.
Smile.
Talk.
Look down.
Move your head.
Do the glasses stay where they should?
Do they feel comfortable?
Do you actually like how you look in them?

And here's a surprisingly important test:

Do you want to keep wearing them?

If the answer is yes, you're probably onto something.

13. Take a Photo

Here's a little trick that can help when you're trying on multiple pairs.

Take a photo.

Why? Because when you've been staring at yourself in the mirror for 30 minutes comparing twelve nearly identical frames, your brain eventually stops being useful.

A photo gives you a chance to step back and look at the frames more objectively.

Even better: take photos of several different styles and compare them later.

You may be surprised which pair wins.

14. Don't Forget Comfort

We know we already mentioned this. We're mentioning it again because it's that important. You're probably going to wear your glasses for hours at a time.

So ask yourself: How do they feel after 10 minutes?

Not just: How do they look after 10 seconds?

Check for:

Pressure behind your ears
Pinching at your temples
Sliding
Pressure on your nose
Excessive weight
Loose or wobbly frames

The perfect pair should feel comfortable enough that you eventually forget you're wearing them.

15. Buy the Glasses You'll Actually Wear

This sounds obvious.

But it's easy to get distracted by what looks cool on someone else.

Maybe oversized frames look fantastic on your favourite celebrity.

Maybe tiny wire frames are having a moment.

Maybe everyone on Instagram is wearing clear acetate.

Great.

But your glasses aren't Instagram's glasses.

They're yours.

Choose something that fits your face, your lifestyle and your personality.

Trends come and go.

A pair you love wearing is much more valuable.

Once You've Found the Perfect Pair, Keep Them Looking Perfect

So you've done it. You found the pair.

They fit just right, the colour looks great, and you actually feel pretty good wearing them. Nice work. 😎

Then you put them on and suddenly notice every crumb on the kitchen counter, every speck of dust in the room, and approximately 17 fingerprints you swear weren't there five minutes ago.

Welcome to owning glasses.

The good news? Keeping them clean is easy.

The bad news? Your shirt isn't the answer. 😉

Even if it looks perfectly clean, clothing can pick up dust and tiny particles that you really don't want rubbing across your lenses.

Instead, keep a dedicated microfiber lens cloth handy. A quick, gentle wipe is all it takes to get rid of those everyday fingerprints, oils and smudges—and get you back to seeing things clearly.

Your glasses deserve better than your T-shirt.

Frequently Asked Questions About Choosing Glasses

How do I choose the right glasses for my face?

Start by considering your face shape, but don't feel restricted by it. Round faces often pair well with angular frames, while square faces can look great with softer, rounded shapes. Oval faces generally work well with many frame styles.

Most importantly, choose a frame that fits comfortably and that you genuinely like wearing.

Should glasses be wider than your face?

Generally, your frames should be reasonably proportionate to your face. Frames that are significantly too wide can slide around, while frames that are too narrow may feel uncomfortable.

The best way to judge is to try them on and check both the fit and proportions.

How should glasses fit?

Your glasses should sit comfortably on your nose, stay relatively secure when you move your head, and shouldn't pinch your temples or ears.

Your pupils should also sit reasonably well within the lens area.

How do I know what size glasses I need?

Check the measurements printed on a pair of glasses that already fits you well. These usually include lens width, bridge width and temple length.

You can use those measurements as a starting point when shopping for a new pair.

What glasses look best on a round face?

Angular, rectangular and square frames can create a nice contrast with the softer lines of a round face.

That said, there are no hard rules. Try different shapes and see what makes you feel great.

What glasses look best on a square face?

Round and oval frames can soften the appearance of stronger facial angles. Softer shapes can provide a nice contrast to a defined jawline.

Are expensive glasses better?

Not necessarily.

Price can reflect things like materials, craftsmanship, brand, lens technology and design, but expensive doesn't automatically mean a frame is the right choice for you.

Focus on fit, comfort, quality, prescription needs and style.

Should I buy glasses online or in person?

Both can work.

Buying online can offer convenience and a large selection, while shopping in person gives you the opportunity to try frames on and get help from an optical professional.

If buying online, make sure you have the correct prescription, PD and frame measurements.

How often should I replace my glasses?

There's no universal replacement schedule.

Replace your glasses when your prescription changes, your frames become damaged, your lenses become significantly scratched, or your current pair no longer meets your needs.

Regular eye exams can help determine whether your prescription has changed.

Final Thoughts

Finding the right pair of glasses really doesn't have to be complicated.

Start with the basics: make sure they fit well, know your measurements, think about your lifestyle, and—most importantly—pick something you actually love wearing.

Then have a little fun with it.

Try the frame you normally wouldn't pick.
Try that colour you've been eyeing but aren't quite sure about.
Go a little bolder than usual.

You might just surprise yourself.

Because your glasses aren't just there to help you see. They're part of your look, your personality, and, let's be honest, they're sitting right in the middle of your face. 😎

And once you've found the pair, take care of them.

Keep those lenses clean, skip the shirt, and keep a WowyWipe nearby for those inevitable fingerprints and smudges.

Clear vision looks good on you. 👓✨
