AR Eye is a free augmented reality application designed for iPhone users that simulates the visual experiences of individuals with cataracts and the differences between monofocal and multifocal intraocular lenses after cataract surgery. The app aims to enhance understanding of how cataracts affect vision and assist users in making informed choices regarding lens options that best suit their lifestyles. By utilizing the smartphone's camera, users can experience realistic simulations of various visual scenarios related to cataracts.

This app not only serves potential cataract patients by providing a pre-surgery visual experience, but it also helps family members of patients understand the challenges faced by those with cataracts. The application is designed under medical supervision to ensure accuracy, although users should be aware that results may vary based on their device's camera capabilities. The app strives to be compatible with a wide range of devices, but some may not be supported.
