Contact lenses can turn yellow overnight due to a variety of reasons, including exposure to air and light, buildup of protein and lipid deposits, and inadequate cleaning and storage. When contact lenses are exposed to air and light, they can undergo a process called oxidation, which can cause them to turn yellow.

Additionally, the buildup of bacteria and other microorganisms on the lenses can contribute to the formation of a film. This film can not only cause discomfort and irritation when wearing the lenses, but it can also increase the risk of eye infections and other complications. Therefore, it is important to follow proper contact lens care and wear guidelines to avoid these issues. **
