  • Research summary

    Presbyopia is a chronic, age-related gradual loss of the ability of the eye to change focus in order to be able to see objects at near distances. According to the 2011, UK Census, approximately 26.5 million of the population were over the age of 45. As the population ages, the need for options to correct near vision increases.\n\nCurrent optical options for presbyopes include reading glasses, bifocal and multifocal glasses and contact lenses, and in some cases refractive surgery is performed.\n\nContact lens vision correction is achieved using monovision contact lenses (where one eye is fully corrected for the distance and the other eye is corrected for the near vision) or multifocal contact lenses (both eyes have distance and near vision correction). \n\nVerily Life Sciences LLC is conducting a study using commercially available contact lenses and comparing the visual performance at near and intermediate distances achieved when the lenses are specifically fitted to correct intermediate and near vision as compared with when multifocal lenses are fitted.\n
