What is a common application of biomaterials in the eye?

Contact lenses are a common application of biomaterials in the eye because they are designed to be biocompatible and allow for vision correction while being in close contact with the sensitive tissues of the eye. These lenses are made from materials that are not only safe for long-term use but also enable oxygen permeability, which is essential for maintaining eye health. The development of contact lenses has significantly advanced due to the understanding of biomaterials, which prioritize comfort and compatibility with the natural biological system. This application highlights the functional design of materials that can restore or enhance a key sensory function—vision—while ensuring patient safety and comfort.

In contrast, stents are typically used in vascular applications, dialysis machines are associated with kidney function, and cochlea implants are used for hearing restoration. Each of these applications pertains to different medical fields and utilizations of biomaterials, further illustrating why contact lenses stand out in the realm of eye-related applications.
