Understanding how sunglasses are measured can help you to find the perfect pair that not only complements your style but also fits comfortably. 

Let’s look into the intricate world of sunglasses measurements.

Understanding the Three Key Measurements

Sunglasses are measured by three critical dimensions: lens width, bridge width, and temple length. These measurements, typically indicated in millimetres, play a crucial role in determining the fit and comfort of your shades. You’ll often find these dimensions discreetly labelled on the inner temples (arms) of your sunglasses, demarcated by symbols like a square, dash, or space. For instance, a measurement of 63 [] 18 145 denotes lens width, bridge width, and temple length respectively.

How to Determine Your Sunglasses Size

Finding sunglasses that fit perfectly can sometimes feel like a daunting task. However, armed with a simple ruler and a bit of guidance, you can accurately ascertain your sunglasses size. Begin by horizontally placing a ruler across your face to measure the distance between your temples. This measurement, typically in centimetres or inches, serves as a reliable indicator of your ideal sunglasses size.

Refer to the following guidelines to match your face size with the corresponding sunglasses size:

• Face Size (cm) Face Size (inches) Sunglasses Size
• 11.5cm – 13cm 4.5” – 5.1” Small
• 13.5cm – 14cm 5.25” – 5.5” Medium
• 14.5 – 16cm 5.75” – 6.25” Large

Ensuring a proper fit not only enhances comfort but also prevents your sunglasses from slipping or causing discomfort during extended wear.

Decoding the Numbers

Ever wondered what those three numbers on your sunglasses signify? Allow us to elucidate:

• Lens Width: The first number represents the lens width, measured in millimetres from the widest outer edges of one lens to the other.
• Bridge Width: The second number denotes the bridge width, measured as the inner-most distance between the lenses. Subtracting three from this measurement provides the bridge width.
• Temple Length: The third number signifies the temple length, measured from the hinge to the bend and then from the bend to the temple tip.

By understanding these measurements, you gain valuable insights into the dimensions of your sunglasses frame, ensuring a snug and comfortable fit.

Essential Information About UV400

In the realm of sunglasses, UV400 reigns supreme. This designation signifies that the lenses can protect your eyes from ultraviolet (UV) light up to the 400-nanometer wavelength, safeguarding against the most harmful range of electromagnetic exposure. UV400 lenses offer comprehensive protection against both UVA and UVB rays, shielding your eyes from potential damage.

Contrary to popular belief, the darkness of sunglasses lenses does not correlate with their UV protection capabilities. Instead, it primarily affects visual comfort by absorbing varying degrees of visible light. Hence, whether your sunglasses boast a dark or light tint, ensuring they feature UV400 protection is paramount for safeguarding your ocular health.

Understanding CE Markings

If you’ve ever noticed the “CE” mark adorning your sunglasses, you might wonder about its significance. CE, short for Conformité Européenne (French for “European Conformity”), indicates compliance with EU health, environmental, and safety regulations. Sunglasses bearing the CE mark adhere to stringent quality standards, ensuring they meet the necessary requirements for consumer safety and protection.

Ordering Glasses Online: What You Need to Know

In the era of online shopping, ordering glasses or sunglasses from the comfort of your home has never been easier. To streamline the process, familiarize yourself with your ideal lens width, bridge width, and temple length. Additionally, for prescription lenses, ensure you have an up-to-date prescription and know your pupillary distance—the distance between your pupils in millimetres.

Armed with these measurements and insights, you can confidently navigate the world of sunglasses, finding the perfect pair that not only fits impeccably but also offers superior eye protection and style. So, the next time you embark on a quest for the ideal shades, armed with knowledge, you’ll undoubtedly make a choice that leaves you looking and feeling your best.
