Abstract

Color blindness is an optical impairment, caused by a genetic defect which results in a decreased effectiveness of the rods and cones which detect certain wavelengths of light, commonly known as color perception. Because the defect is on the X chromosome, the majority of people affected are male. In patients with colorblindness, this can cause difficulty discerning between certain colors. Current solutions include costly sunglasses to alter the vision, or simply working around this handicap. This could include memorizing where colors are in stoplights, charts, and other color-coded indicators found everywhere in daily life. In this Capstone design, we create a color corrective contact lens for everyday use to allow an individual see the full color spectrum. This is done utilizing a rhodamine-B dye which acts as a light filtration system that shifts the wavelengths for the target color, so that the eye is able to detect that color. This is a rigid gas permeable (RGP) contact lens with a dye treatment that will enhance the color perception of patients with colorblindness. It will be compatible with deuteranopia (commonly known as red/green colorblindness). The hope for the future of the product is to integrate the filter with a patient’s individual eye prescription.
