【Test Lenses】 266 test lenses are made of glass with plastic frames, providing accurate diopter and high light transmission, which is very important for optometrists and vision testers.
Easy to distinguish - Colorful plastic frames help distinguish lenses with different functions. Each lens grip is labeled and the power of the lens is printed on the plastic lens tray.
HIGH QUALITY MATERIAL - Inner diameter 26mm and outer diameter 38mm, providing lightweight and durable using experience, allowing accurate test results. The space is widened, making it easier to insert tabs from top to bottom. The removable tray can be easily placed in the drawer of the combined optometry table.
【Comes with Leather Box】The box is made of high quality leather and comes with a combination lock. Pressing the button outward opens the lock and pushing it inward resets the code to your favorite 3-digit number. Remember the password you set, otherwise you will not be able to open or close it.
WIDE APPLICATION - Very useful for optometrists, vision testers and for home use to check patients' refractive errors - including farsightedness, myopia, presbyopia, astigmatism, strabismus or color blindness.
