As we age, so do our eyes. What many people experience as they age is the need to wear bifocals, or even trifocals, to see properly.
Why do We Need Bifocals?
Bifocals and trifocals have been around for decades. They help people (generally over the age of 40) with an age-related eye issue called presbyopia. Both bifocals and trifocals help restore a full range of sight and specifically help restore reading vision lost to presbyopia.
Presbyopia is the normal loss of the ability to focus on things that are near. Most people notice it when they begin to experience issues focusing on fine text print or even the font on their phones during text message conversations.
This condition is different from nearsightedness and it happens to everyone, even if you have never had a vision problem before.
What are Bifocals?
Bifocals have two lenses in one in order to see things at a distance and near to you. Trifocals feature a third zone on the lens used for intermediate distances between 18-24 inches away. This zone is ideal for seeing your computer, speedometer, or gas gauge.
Bifocal and trifocal lenses have visible lines across them called “seg” lines. These lines outline the segments of the lenses that correct near vision. Despite the lines across the lenses, many people still wear bifocals or trifocals to correct their vision. With some patients, bifocals or trifocals are preferred because they provide a wider zone of viewing than other types of lenses.
