A planned lens replacement regimen is designed to prevent these conditions. A human eye gives the sharpest vision when it is perfectly spherical, that is, round like a basketball. Information is transmitted as impulses from these cells to the brain via the optic nerve. The quantity of light entering the eye is regulated by the iris. The pupil is the variable-sized black circular opening in the center of the iris.
Contact lenses are a great option for vision correction when playing sports.
Contact lenses are stable and do not nterfere with your game. Colored contact lenses are available in various colors and shades. There are lenses available to enhance a light eye and lenses that will change a brown eye to blue, green, violet, hazel and many other colors. They work and they are fun. There are many choices available in lens cleaning and disinfecting.
