Description

Each disc is filled with dots of various colors and sizes. Due to the difference in color and brightness of the small dots, people with normal color vision can easily distinguish these numbers, while people with color blindness cannot see or have difficulty distinguishing the numbers or paths hidden behind.
A professional test book, it is a simple and accurate method for detecting congenital color blindness and red-green blindness, each in complete and incomplete form. It includes four special test panels to determine the type and degree of color vision deficiency.
It takes advantage of the characteristic that blue and yellow appear brighter than red and green when red-green color blindness occurs.
Swatches are housed in specially designed album-style books for easy access. Include detailed instructions.
It is suitable for clinical ophthalmologists, neurologists, and surgeons to assist in the diagnosis of fundus diseases and optic center diseases.
