DIMS Lenses for Myopia Control: How They Work

Introduction

Myopia (nearsightedness) is a growing concern worldwide, especially among children. DIMS (Defocus Incorporated Multiple Segments) lenses are an advanced optical solution designed to slow down myopia progression while maintaining clear vision. Let’s explore how these lenses work and why they are effective for myopia control.

1. What Are DIMS Lenses?

DIMS lenses are a breakthrough in myopia management. Unlike standard single-vision lenses, which only correct blurry vision, DIMS lenses incorporate special defocus segments to signal the eye to slow down growth, reducing myopia progression over time.

2. Key Design Factors of DIMS Lenses

🔹 Central Clear Zone

• The lens has a 9-10 mm central optical zone for clear distance vision.

• Ensures that wearers do not experience blurred vision while benefiting from myopia control effects.

🔹 Peripheral Myopic Defocus

• Surrounding the central clear zone, the lens contains hundreds of tiny defocus segments.

• These segments shift light in front of the retina, which signals the eye to reduce axial elongation, the main cause of myopia progression.

🔹 Multiple Defocus Segments

• Unlike progressive or bifocal lenses, which have only a single defocus area, DIMS lenses feature hundreds of 1 mm defocus segments.

• This uniform defocus distribution helps ensure consistent myopia control across different viewing angles.

🔹 Balanced Optical Zones

• DIMS lenses use a 50% clear vision / 50% myopic defocus ratio, arranged in a honeycomb pattern.

• This balance ensures effective retinal defocus while maintaining good vision quality.

🔹 Smooth Transition Between Zones

• The transition from the central clear zone to the defocus segments is seamless, reducing adaptation issues.

• This minimizes visual disturbances such as ghosting or double images.

🔹 High-Quality Lens Materials & Coatings

• High-index materials keep the lenses thin and lightweight, ideal for children.

• Anti-reflective coatings enhance contrast sensitivity and reduce glare.

• UV protection is often included to protect against eye strain and long-term retinal damage.

🔹 Stability Across Different Viewing Angles

• Unlike traditional progressive lenses, which lose their effect in different gaze positions, DIMS lenses maintain myopic defocus consistently.

• Whether looking straight ahead or off-center, the defocus effect remains stable.

3. Why Are DIMS Lenses Effective?

✔ Provides myopia correction and control simultaneously
✔ Uses consistent peripheral defocus to slow axial elongation
✔ Minimizes visual discomfort for better adaptation
✔ Ensures clear central vision while managing myopia progression

Conclusion

DIMS lenses are a scientifically backed, innovative solution for myopia control. By combining standard vision correction with peripheral myopic defocus, these lenses provide clear, comfortable vision while helping to slow down the worsening of nearsightedness. If you’re concerned about progressive myopia, DIMS lenses could be a game-changing option for long-term eye health.
