How to Choose the Best Frames for Your Face

Mirror, mirror on the wall….You have probably seen or heard that the best way to determine which eyeglass frames are ideal for your face is based on geometric shapes.  The truth is: most people’s faces aren’t perfectly shaped like a heart, circle, square, or any other strictly defined category.  Most faces are actually a combination of a few different shapes: rounded chins and tall foreheads, angular features and tapered jaws, and many other magnificent features that make each person unique.


So many shapes, so many frame styles, so confusing!

The goal is to find the shape that looks the most like yours even if your chin is a little more pointed than the typical oval, or if your forehead a little wider than the typical  inverted triangle. These are all just guidelines to help you determine how to balance and complement your features.

With so many frame styles to choose from, knowing what works best can really help bring out your unique features and attributes. Whether you have an oval, round, heart, diamond or square shaped face, this face shape guide help you choose the glasses that are best for you!

Glasses For Oval Faces

Glasses for oval faces can own almost any aesthetic. People with oval faces have evenly proportioned features which gives them the most style options to choose from. They can experiment and be as adventurous as they want!

Do You have an oval face shape?
Step in front of the mirror and check yourself out. Oval face shapes are characterized mostly by a softly curved jawline. Plus, the width of your forehead should be just a bit wider than your chin, with your cheekbones usually placed just a little higher on the face.

Glasses For Square Faces

When it comes to choosing stylish glasses, people with square faces have the chance to be bold and expressive.  The key is to search for glasses with round frames.  Round frames are perfect for adding contrast to your strong face shape and jawline and can balance out your most striking facial features.

Do You have a square face shape?

Step in front of a mirror and check yourself out. From the top, people with square faces have broad foreheads that are wider from side to side. Their cheeks are not angled and placed higher like on other faces but remain in line with the other features on their face. Lastly, a clear sign is the shape of the chin. A square face’s most prominent characteristic is a strong horizontal jawline.

Glasses For Round Faces

The key to finding the perfect eyewear is all about creating contrast and balance between your face shape and the frame you have chosen. For round faces, fashion experts from around the world agree that rectangular and square frames will keep you looking sharp and stylish.  Your search should start with a frame that features a strong, angular structure.

Do You have a round face shape?

People with round faces have a fuller shape to their cheeks, which often gives them a more youthful appearance.  They also have foreheads that are wider at the top rather than narrow. Another telling feature is that, nearing the bottom of the face, people with round faces usually have rounder chins than other face shapes. In some instances, a more subtle jawline is also a sure sign that you do indeed have a rounded face.

Glasses For Heart-Shaped Faces

Finding the right pair of eyeglasses for your heart shape face may feel daunting, but we have the inside track on how to find a frame!  Whether you are looking for men’s or women’s eyeglasses, the best glasses for heart shape faces are rectangle, oval or wayfarer. Heart shaped faces feature curved lines and elegant angles.

Do You have a heart-shaped face?

Standing in front of a mirror, use your fingers to trace the outline of your face.  Heart shape faces are widest at the forehead, have high cheekbones, and taper down to a narrow chin.  This face type has a mixture of curves, angles, and lines. That means some faces are rounder and more heart shaped, while others are more linear and angular, much like an upside-down triangle.

Glasses For Diamond Faces

For diamond faced individuals, fashion stylists recommend eyeglasses that contrast or soften the angles of your face — including oval, rectangle, and horn-rimmed frames.  Oval glasses help soften the strong, angular features of your face.  Glasses with a rectangular frame shape offer contrast to your facial features, while horn or cat-eye eyeglasses extend beyond your brow to help bring more balance to the structure of your face.

Do you have a diamond face shape?

The best way to tell is to take a selfie and trace the outline of your face.  If the shape you drew is wider in the middle than at the top and the bottom, you have a diamond shaped face. The angles and lines created by your facial features work well with more curved frame shapes. You can also try out some more daring styles, like eyeglass frames with strong brow lines or more pointed temples.

Glasses For Oblong or Rectangle Faces

Due to the length of your face, you want frames that will make your face appear a little wider and shorter. Square frames with some detail in them or even some color in the top half will do just that. You may even choose wide glasses with curvy edges as they will also make your face look wider. 

Do you have a rectangular face shape?

Rectangular faces are typically associated with having a higher forehead, and angular edges usually represent this shape. A rectangle face shape is quite symmetrical in that the width of the forehead, jawline and cheekbones are almost the same. The jaw area has more of a squared off shape and the length of the face is longer than the width, just like a rectangle. The overall symmetry of the face will appear monotonous and consistent. The jaw area has more of a squared off shape and the length of the face is longer than the width.
Oblong faces are very similar, but they have a rounded jawline, while rectangles have a square, angular jaw.

Junk Light, Disrupted Sleep, and Your Health

Exposure melatonin disrupting junk light can have have effects on many aspects of your health

Sleep cycle disruption

Junk light exposure when traveling can disrupt your circadian rhythm. Long-term exposure to light at night which accompanies shift work is listed as a probable carcinogen by the World Health Organization. Light at night has shown to be highly associated with significantly the risk of hormone specific such as cancers of the breast and prostate.


The flickering wavelength of light associated with LEDs and compact fluorescent lights emit blue light that inhibits melatonin production but also create a unique glare that impacts your retina causing eye strain, headaches, and physical and mental fatigue.

Weight Gain

Red light and darkness move leptin and ghrelin into patterns that are (context dependent) associated with less hunger, while blue light does the opposite and can move both into patterns associated with more hunger.

Anxiety/Depression & Depression

Increase in cortisol, the stress hormone, due to circadian disruption. Memory recall is impaired with consistent sleep deprivation and may leave you distracted and not performing your absolute best.

The Importance of Melanopsin Cells

The Key to Better Sleep

detects blue light

The melanopsin cells detect blue light it tells your brain that it is “daytime” and less melatonin is produced.

sending signals to your brain

The signals to your brain to alert brightness and for the brain to increase or suppress the sleep hormone, melatonin.

Light Source

Melanopsin cells can’t differentiate the blue light that occurs naturally form the sun from the junk light emitted from your computer monitor.

Harness Your Biology to Fight Junk Light

Your body requires some blue light at the right time of day and from the right sources. That’s why we created TrueDark® Sleep Technology that gives you 24-protection from junk light day and night.

Use TrueDark® Twilights When You’re Ready for Sleep

Stop Junk Light with TrueDark® Twilight technology that frees your hormones and neurotransmitters to do their best work.

When the sun goes down, blue light isn’t the only junk light that can disrupt our sleep cycle and more than blue blockers are needed. TrueDark® Twilight is the first and only solution that is designed to work with melanopsin, a protein in your eyes responsible for absorbing light and sending sleep/wake signals to your brain. Without melanopsin, melatonin can’t be accessed.

When you wear your Twilights for as little as 30 min before bed you prevent your melanopsin from detecting the wrong wavelengths of light at the wrong time of day. This supports  your circadian rhythm and helps you fall asleep faster and get more restorative and restful sleep.

TrueDark® Daywalkers for Your Waking Hours

The highly advanced lenses in TrueDark® Daywalkers operate on a more advanced level than traditional blue blockers.

Blue light emitted from the sun helps regulate our sleep/wake cycle. However, in today’s world, we’re exposed to an overabundance of blue light, or junk light from artificial light. This includes hours spent in front of  TVs, phones, and computers. It also includes time spent in artificial man made light with LEDs and fluorescent lights. Even if we’re simply reading a book, we’re doing that in artificial light which emit dramatically more blue light than the sun. That overexposure to junk light during the day has a dramatic impact on our neurotransmitters and hormones that are responsible for quality sleep.
