Do Myopia Control DIMS Lenses for Children Really Work?

Myopia (nearsightedness) is a growing concern among children, with increasing screen time and reduced outdoor activity contributing to higher rates. DIMS (Defocus Incorporated Multiple Segments) lenses have emerged as a promising solution for slowing myopia progression, but do they really work? Let’s explore the research and real-world effectiveness of DIMS lenses.

1. What Are DIMS Lenses?

DIMS lenses are specialized spectacle lenses designed to slow the progression of myopia in children. Developed by researchers at the Hong Kong Polytechnic University, these lenses combine a clear central zone for normal vision with multiple defocus segments around the periphery to control eye growth.

2. How Do DIMS Lenses Work?

Myopia progresses as the eyeball elongates, causing distant objects to appear blurry. DIMS lenses create controlled peripheral defocus, signaling the eye to slow its growth. This method is based on scientific studies showing that peripheral retinal defocus can influence eye development.

3. Are DIMS Lenses Effective?

Clinical studies have shown promising results:

• A three-year study found that children wearing DIMS lenses experienced a 52% reduction in myopia progression compared to those wearing standard single-vision lenses.

• Eye elongation was also reduced by 62%, which is key to slowing myopia advancement.

4. How Do DIMS Lenses Compare to Other Myopia Control Methods?

DIMS lenses are one of several myopia control options, including:

• Orthokeratology (Ortho-K): Rigid contact lenses worn overnight to reshape the cornea.

• Atropine Eye Drops: Low-dose atropine can slow eye elongation.

• Multifocal Contact Lenses: Similar to DIMS lenses but in contact lens form.

While all these methods are effective, DIMS lenses offer a non-invasive, easy-to-wear option that doesn’t require daily medication or overnight lens wear.

5. Are DIMS Lenses Right for Your Child?

DIMS lenses are best suited for children diagnosed with progressive myopia. They are particularly beneficial for children who may not tolerate contact lenses or atropine drops. However, regular eye exams and lifestyle adjustments—such as spending more time outdoors and reducing screen time—should also be part of a myopia control strategy.

Conclusion

DIMS lenses have been scientifically proven to slow myopia progression in children, making them a valuable tool for parents concerned about worsening nearsightedness. While not a cure, they offer an effective, glasses-based solution with long-term benefits. If your child has myopia, consulting an eye care professional about DIMS lenses could be a smart step toward better vision health.
