Is Astigmatism the Same as Nearsightedness?
★Exhibit Content: Optical imaging differences between myopia and astigmatism, science popularization of refractive error principles ★Interaction: Manual interaction ★Operation: 1. Observe the light box image through simulated myopia lenses and simulated astigmatism lenses respectively, and compare the imaging differences of the two visual defects; 2. Slide the slider to overlap the two sets of lenses and experience the visual effect when both myopia and astigmatism are present. ★Exhibit Description: The exhibit consists of a Q235-1.5mm sheet metal painted display stand, a 12mm Kelesi artificial stone countertop, simulated myopia/astigmatism optical lens sets, a high-precision sliding module, an LED eye-care light box, etc. It is a recommended exhibit for the KexMall exhibit mall. Through intuitive optical simulation comparison, it helps visitors correctly understand the difference between myopia and astigmatism, two common refractive errors, corrects the common misconception that "astigmatism is a type of myopia", and is suitable for eye health science museums. ★Scientific Principle: This exhibit is based on the optical principles of refractive errors: Myopia is when the eyeball is too long or the refractive power is too strong, causing parallel light rays to focus in front of the retina, resulting in blurred distance vision; Astigmatism is when the curvature of the cornea or lens surface is irregular, causing light rays to fail to focus into a single point, resulting in double vision and distortion; The exhibit simulates the imaging effects of two types of refractive errors, allowing visitors to personally experience their differences, understand their optical essence and superimposed effects, and popularize eye health knowledge.
