Fitting Guide

FIND YOUR PERFECT FIT

Choosing the right sunglasses is not just about style — it’s about comfort, balance, and confidence. This guide will help you find the ideal size and frame shape for your face.

FRAME SIZE EXPLAINED

Every pair of sunglasses is designed with specific measurements to ensure a proper fit:

  • Lens Width: The horizontal width of one lens
  • Bridge Width: The distance between the two lenses
  • Lens Height: The vertical height of the lens
  • Temple Length: The length of the arms that rest over your ears

Example Size: 52 – 18 – 140
All measurements are in millimeters and determine how the frame will sit on your face.

HOW TO FIND YOUR SIZE

Option 1: Check Your Current Glasses

Look inside the arm of your existing glasses. You will usually find numbers like: 52 18 140. These represent your ideal size and can be used as a reference when choosing new frames.

Option 2: Measure Your Face

If you don’t have glasses, you can measure your face by checking the width from temple to temple and the width of your nose bridge. This will help you choose a comfortable and well-fitting frame.

  • Large (55–58 mm): Designed for wider or broader faces

UNDERSTANDING BASE CURVE

Understanding Base Curve

The Base Curve (BC) refers to the curvature of the lens and how it fits around your face. It affects comfort, coverage, and performance.

  • Base 2 & 4: Flat, fashion-forward styles with a modern look
  • Base 6: The most common curve, offering a natural and comfortable fit for everyday wear
  • Base 8: Sport-style wrap design that provides better protection from wind and glare
  • Base 9 & 10: High-wrap designs for maximum protection in extreme conditions

Choosing the right base curve ensures better comfort, improved clarity, and proper fit without pressure on your face. Whether you prefer a sleek fashion style or a performance fit, PROGLASSES offers options designed for both style and protection.
