Usage

This lens set is ideal for a variety of clinical environments, including private optometry offices, ophthalmology clinics, teaching hospitals, and mobile eye care units. The 20D lens is commonly used for initial screenings and low power assessments, while the 78D lens provides a versatile middle range for detailed retinal examinations. The 90D lens offers high magnification for advanced diagnostic procedures such as slit‑lamp biomicroscopy and detailed fundus evaluation. Because the lenses are compact and lightweight, they can be easily incorporated into portable examination kits for field work, community health screenings, or home visits. The set is also valuable for training programs, allowing students to experience the full spectrum of lens powers without needing multiple separate instruments.
