• 【Trial Lenses】 266 trial lenses are made of glass with plastic frames, providing accurate diopter and high light transmittance, which is very important for optometrists and vision testers.
• 【High Quality Material】Inner diameter 25mm and outer diameter 38mm, providing a lightweight and dur-able use experience, allowing for accurate test results. The gap is widened, making it easier to insert the tabs up and down, and the plastic inner core is more convenient to use. The removable tray can be conveniently placed in the drawer of the optometry combination table.
• 【Easy to Distinguish】Colored plastic frames help distinguish lenses with different functions. Each lens handle is labeled and the lens power is printed on the plastic lens tray.
• 【Comes with Aluminum Box】The box is made of high-quality aluminum and comes with a combination lock. Pushing the button outward opens the lock and pushing it inward resets the code to your preferred 3-digit number. Remember the password you set, otherwise you will no longer be able to open or close it.
• 【Wide Application】Very useful for optometrists, vision testers and home use to check patients for refractive errors - including farsightedness, myopia, presbyopia, astigmatism, strabismus or color blindness.
