Reflective contact lenses are a type of lens that reflects light back into the eye, providing the wearer with improved night vision. These lenses are often used by people who work night shifts or who have difficulty seeing in low-light conditions. Reflective contact lenses are also used by athletes and soldiers to improve their performance in night-time competitions and missions. While reflective contact lenses can provide a significant advantage in many situations, they also have some drawbacks. For example, reflective contact lenses can cause glare and make it difficult to see in brightly lit environments. Additionally, these lenses can be uncomfortable to wear and may require special care and cleaning.
