In this article, we'll look at why it's important to choose the right sunglasses, how to understand your face shape, the types of glasses that suit each face shape, the materials used to make glasses, and finally, how to look after your sunglasses.

Why is it important to choose the right sunglasses?

UV protection

The main purpose of sunglasses is to protect your eyes from the sun's harmful ultraviolet rays. Prolonged exposure to UV rays can lead to various eye problems, including cataracts and retinal damage. You might be wondering how eyewear can help against UV rays: 

• Lens Materials: Some eyeglass lenses naturally block UV rays. Polycarbonate and high-index plastic lenses are examples of these.
• UV-Blocking Coatings: Certain lenses have transparent coatings that block UV rays without changing the lens's appearance.
• Photochromic Lenses: These lenses darken when exposed to sunlight, providing UV protection. They lighten indoors or when UV levels drop.
• Wraparound Frames: Sunglasses and sports glasses with wraparound frames cover more of your eyes, reducing UV exposure from the sides and top.
• Tinted Lenses: Sunglasses with tinted lenses block UV rays while reducing glare. Darker tints offer higher UV protection.
• Polarized Lenses: Polarized sunglasses reduce glare from surfaces like water and pavement and may also include UV protection.

Visual comfort

The right choice of sunglasses can also improve your visual comfort by reducing glare and improving the clarity of your vision.

Style and aesthetics

Finally, sunglasses are also a fashion accessory that can complement your overall style. Choosing the right glasses can improve your appearance and boost your self-confidence.

Understanding your face shape

There are many different face shapes, including round, square, oval and heart-shaped. Each shape has its own characteristics and requires a specific type of eyewear to complement and enhance your appearance.

How to measure your face shape

To find the perfect frames for your face, here's a fun trick: grab a tape measure and get ready to play! Check out these easy steps:

• Measure those cheekbones, forehead, lower jaw, and face length with your trusty tape measure.
• Oh, and don't forget your handy credit card! Pop one end in the middle of your nose and see where the other end lands near your eye.
• If the card goes past the corner of your eye, you've got a small face.
• If it just touches the corner, you've got a medium face.
• And if it doesn't reach the corner at all, you've got a large face!

So, go ahead and give it a try. You'll be rocking those perfect frames in no time!

Types of glasses according to your face shape

Glasses for round faces

For a round face, opt for oversized sunglasses in dark colours. Cat eyeglasses and aviators are also good options.

Glasses for square faces

If you have a square face, oversized sunglasses will suit you perfectly. You can also opt for round or oval frames in bold colours.

Glasses for oval faces

People with oval faces are lucky enough to be able to wear almost any type of eyewear. However, aviators, cat-eye and butterfly glasses are particularly flattering.

Glasses for heart-shaped faces

For a heart-shaped face, teardrop glasses are ideal. Avoid oversized frames that may exaggerate the width of your forehead.
