Sure, the right shirt counts and decent shoes are crucial to a good first impression; but seeing as people talk to your face more than your chest or feet (we’d hope), the importance of solid eyewear shouldn’t be overlooked.

If the eyes are the window to the soul, it’s time to take care of the flower boxes out front with our crystal-clear guide to corrective specs and stylish shades.

Choosing A Frame To Fit Your Face

Much like a beard, or hairstyle, or indeed beard and hairstyle, the types of frames available to you will be determined by the shape of your face.

There are five main shapes that all faces fall into when it comes to glasses, and around twice as many styles of frames. While this means there is bound to be at least one that suits you, this broad range also opens up plenty of scope for getting it wrong.

To omit any ocular errors, we tapped up eyewear experts at high-end opticians David Clulow to compile a failsafe guide.

Round Faces

We’re sure you love your round face; heck, you’re even in the same category as Justin Timberlake, Leonardo DiCaprio and Daniel Craig, but that doesn’t mean you want to accentuate it. Eyewear 101 states that “you should always look for a frame that goes against the face shape,” according to Tessa Forde, a senior optometrist at David Clulow. “[Therefore,] if you have a round face, go for square frames.”

Narrow, rectangular frames with a strong bridge give the illusion of a longer face, while also providing soft, round faces with definition and structure.

Oval Faces

One of the most common shapes, men with oval faces are fortunate enough to have won the genetic jackpot and suit a range of styles. To add balance to the mix of both rounded and defined elements within your face, opt for frames that are as wide the broadest part (usually the forehead).
