近年来，点扩散光学技术（Diffuse Optical Technology, DOT）镜片在控制近视的研究中取得了重要进展。近视，尤其是儿童和青少年的近视，已成为全球公共卫生问题。DOT镜片通过降低视网膜对比度信号，减少眼轴增长，进而有效延缓近视进展。本文综述了DOT技术的基本原理、设计特点及其在近视防控中的应用进展。临床研究表明，DOT镜片能够显著减缓儿童的近视发展，同时保持较好的视觉质量和安全性。尽管DOT技术显示出良好的潜力，但长期有效性及安全性尚需进一步验证。未来的研究应继续探讨DOT镜片在不同人群中的应用，并结合其他近视干预措施，进一步优化其效果

In recent years, Diffuse Optical Technology lenses have made significant advances in myopia control research. Myopia, particularly in children and adolescents, has become a global public health concern. DOT lenses work by reducing retinal contrast signals, thus limiting axial elongation and effectively slowing down the progression of myopia. This review summarizes the basic principles of DOT technology, its design features, and its application in myopia control. Clinical studies have shown that DOT lenses can significantly reduce myopia progression in children while maintaining good visual quality and safety. Despite the promising potential of DOT technology, further research is needed to confirm its long-term efficacy and safety. Future studies should explore the application of DOT lenses in different populations and optimize its effects by integrating other myopia control measures
