Researchers at the ZEISS Vision Science Lab have developed new instruments for assessing specialized eyeglass lenses aimed at slowing myopia progression, or nearsightedness, particularly in children. This innovative approach accurately measures the optical properties of the lenses under real-world conditions by simulating the pupil and refractive errors characteristic of myopic eyes. The urgency for such advancements is underscored by the alarming prediction that half the global population will be nearsighted by 2050, with children’s cases particularly concerning as their eyes grow.
The study details the development of a new instrument that utilizes rotating light and a spatial light modulator (SLM) to replicate the aberrations caused by different viewing angles unique to myopic eyes. This allows for thorough analysis of how different lens designs interact with retinal signals. Initial findings suggest that understanding these interactions could lead to enhanced lens designs and treatment efficacy, benefiting millions of children with myopia. Furthermore, the research raises important questions about the relationship between various lens properties and their clinical effectiveness, paving the way for improved myopia management strategies in the future.
