Myopia and Hyperopia Correction Demonstrator Model, The Panel is Made of Metal, Education and Teaching Equipment Tools.

Instrument operation:First put the instrument on the test bench, install two AA batteries (note the positive and negative poles) on the three-line light source, toggle the switch, and check whether the light source is turned on and whether the five lenses are damaged. Then, place the light source on the right side of the demonstration table, let the students understand the internal structure of the eyeball, and the demonstration begins.2. If presbyopia (hyperopia) is farther than the retina, it must be corrected with presbyopia lenses (convex lenses).3. Where will the myopia be, and what lens should be used to correct it?Through this instrument, students can learn the structure of the eyeball, the formation of myopia and hyperopia, and the correction of myopia and hyperopia.❤ I am very happy that you can visit my shop, I wish you a one-stop shopping, happy shopping!

• ✔ The high-quality comparison model of myopia and hyperopia can easily communicate with patients or achieve the purpose of teacher-student education by comparing eyeball imaging.
• ✔ 3D visual effects, suitable size can better present the process of eye lesions, and provide patients and students with more 3D visual effects.
• ✔ The high-quality cross-section can clearly show the anatomical structure of the eyeball, the color is full and lifelike, and the internal structure is clearly visible for easy observation.
• ✔ Made of smooth resin, environmentally friendly, non-toxic, safe and durable, the lens material is acrylic, safe, durable and practical.
• ✔ The physical optics experiment set will give your child a deeper understanding of physical optics, making learning easier and more enjoyable.
