Annotation. Relevance. This article provides an overview of lenses based on their type and optical power. Lenses are clear optical devices that are used to focus light or change the appearance of images. The article describes different types of lenses, including converging and diverging lenses. This article provides a concise and clear explanation about lenses, their role in optics, and their applications in medicine and other fields. 1. Scientific aspect: Lenses and their optical power are fundamental concepts in the field of optics. The study of their properties and characteristics contributes to expanding our knowledge of optics and contributes to the development of new technologies. 2. Technical aspect: Knowledge of different types of lenses and their optical powers is necessary for the design and application of optical systems in various technical fields including photography, microscopy, telescope and other optical devices. Optimizing optical systems requires a deep understanding of the relationship between lens types and their optical power. 3. Medical aspect: The study of different types of lenses and their optical powers is important for the development and design of optical systems used in medical practice, such as glasses, contact lenses and optical instruments for eye surgery. Understanding these concepts helps in improving vision and maintaining eye health. Purpose of the study. Master methods for determining the focal lengths of converging and diverging thin lenses. Tasks to be solved: — acquire skills in aligning centered optical systems; — master methods for measuring the focal lengths of converging and diverging lenses; — observe the dependence of the image type on the position of the object relative to the focus of the lens. Materials and methods. Converging lenses, also known as convergent lenses, focus light rays into one point and are used to correct myopia. Diverging lenses scatter light rays and are used to correct farsightedness. The optical power of a lens is measured in diopters and depends on its shape, size and material. Results and conclusion. The higher the numerical value of the optical power of a lens, the stronger the lens. Positive values indicate a straight lens, and negative values indicate a convex lens. For example, a lens with a power of +2.00 D will collect light rays to correct near vision, while a lens with a power of –3.00 D will diffuse light rays to correct farsightedness. Lenses are an important tool in ophthalmology for vision correction and treatment of various eye diseases.
