Many people develop presbyopia for example, as they age. Certain vision conditions can cause people to need trifocal lenses. Trifocals are best suited for people who need vision correction at multiple distances. The lower portion of a trifocal lens is for close activities, such as reading. The middle portion of the lens corrects for intermediate vision, which helps for seeing objects at about an arm’s length away. The top portion of a trifocal lens corrects for distance vision, for activities such as driving. Because of these lines, vision can be blurred between each focal range.

First, the distance vision prescription is made on the lens, followed by the intermediate vision prescription for the middle of the lens, and then the near vision prescription on the lower portion of the lens. Trifocals are made by putting three different vision prescriptions on one lens. But anyone who needs help with the three fields of vision could benefit from trifocal glasses. Trifocals are typically recommended for people over the age of 40 who have a pre-existing vision condition and are starting to experience presbyopia.
