How to Choose Eyeglass Frames for High Myopia? A Comprehensive Guide

The Growing Prevalence of High Myopia

As of 2020, there were approximately 163 million individuals worldwide with high myopia, a number expected to rise to 938 million by 2050. Adolescents account for about 10% of this population. This increasing prevalence makes it crucial for eyewear professionals to understand the specific needs of high myopia customers.

While many optical professionals are experienced in selecting lenses for high myopia, the importance of choosing the right eyeglass frames is often overlooked. This guide provides key insights into frame selection for high myopia, combining industry knowledge with our expertise at HPGlasses.

• Frame Size Matters

Each frame has its dimensions marked on the temple arm, typically in this format: 56□15-148. Here, 56 represents lens width, 15 is the bridge width, and 148 is the temple length (all in millimeters).

Why do some frames make lenses appear thinner, even for the same prescription? It’s all about frame size. Properly sized frames can significantly reduce lens thickness. For instance, a well-chosen frame can make an 800-degree prescription appear as thin as a 500-degree one.

To estimate how a frame will affect lens thickness, use this formula:
(Lens Width + Bridge Width - Your Pupillary Distance) ÷ 2
The smaller the result, the thinner the lenses. Ideally, keep this number under 5mm for a thinner lens profile.

Frame Width Recommendations:

• For Men:

• Pupillary Distance (PD) 60–65mm: Choose frames with ~50mm lens width.
• PD 65–70mm: Choose frames with ~53mm lens width.

• For Women:

• PD 56–60mm: Choose frames with ~47mm lens width.
• PD 60–64mm: Choose frames with ~50mm lens width.

Avoid oversized frames, especially those with lens widths exceeding 54mm, as they increase the risk of optical distortion and lens thickness.

• Stability is Crucial

High myopia lenses are heavier and require frames that provide stability. Look for frames with:

• Wide nose pads for better weight distribution.
• Non-slip temples and adjustable nose pads to prevent sliding.
• Durable materials like pure titanium, which is lightweight and strong.

At HPGlasses, our titanium frames are ideal for high myopia. They are hypoallergenic, corrosion-resistant, and designed for all-day comfort.

• Maintain Proper Vertex Distance

The vertex distance (distance between the lens and the eye) should be 11–12mm. A slightly larger distance is better than one that’s too small. Improper vertex distance can lead to overcorrection and visual fatigue.

• Avoid Excessive Tilt or Curve

Frames with excessive tilt or curvature can distort vision. Ideally, the frame’s tilt angle (pantoscopic tilt) should be between 8–10 degrees to avoid overcorrection.

• Full-Frame or Rimless?

For high myopia, full-frame glasses are generally the best choice as they conceal the lens thickness effectively and provide greater support. However, rimless glasses can also be an excellent alternative for those seeking a lighter option.

One unique advantage of rimless glasses is their customization potential. At HPGlasses, we offer bespoke lens shapes and sizes to match your preferences. For example, if you like the design of Frame A but prefer the lens shape of Frame B, we can tailor the lenses to combine the best of both.

• Ensure Accurate Pupillary Height Measurement

Accurate pupillary height (vertical alignment of the lens to the pupil) is essential for high myopia lenses. This ensures proper alignment of the optical center, reducing visual discomfort.

Professional Eyewear Fitting Matters

Selecting frames for high myopia requires a balance of aesthetics and functionality. Trusting professionals with the right expertise and equipment is critical.

Recommended Places for Eyewear Fitting:

1. Renowned eye hospitals or ophthalmology clinics.
2. Optical stores with certified optometrists.
3. Well-equipped vision centers.

Places to Avoid:

1. Mall kiosks with limited expertise.
2. Shops with outdated equipment.
3. Non-certified optical stores.

Frame Styles for Different Face Shapes

• Round Face: Rectangular or angular frames.
• Square Face: Round or oval frames.
• Long Face: Elongated rectangular frames.
• Heart-Shaped Face: Oval or thin frames.
