Abstract
A contact lens packaging container and a contact lens product are provided. The contact lens packaging container is formed by a plastic material and a color powder material dispersed in the plastic material. The contact lens packaging container has a light blocking rate of not less than 20% under a wavelength measurement range between 380 nanometers and 780 nanometers through a spectrophotometer.
