What Are Digital Progressive Lenses?
Digital progressives lenses, or high-definition lenses, are lenses in eyeglasses that provide sharper vision than regular progressive lenses. Advances in lens manufacturing allow digital progressives to correct a patient's vision while reducing glare when driving at night and providing sharper vision in all lighting conditions, according to All About Vision.
All types of progressive lenses correct a condition called presbyopia, the loss of the eyes' ability to change focus to see objects that are nearby, according to About.com. Presbyopia develops around age 40. Because presbyopia is caused by aging, everyone will develop it. Progressive lenses are also called no-line bifocals, and they come in a range of cost levels, according to About.com.
