Varilux lenses are a type of corrective lenses that provide a continuous field of vision while removing the visible lines that are present in bifocal and trifocal lenses. They are typically used in glasses intended for patients who suffer from presbyopia, the loss of ability to focus on nearby objects.
Varilux progressive lenses combine multiple lens powers and provide a seamless progression between them, allowing the patient to look at near and distant objects without sudden transitions in focus. They can be personally tailored to the patient’s needs to avoid eye strain and headaches. Some patients may require up to two weeks to adapt to the changes that the Varilux lenses introduce to their peripheral vision, although the adaptation normally takes only a few hours.
