It is normal for people to experience new problems with vision as they age, especially after reaching their fortieth birthday. The lens of the eyes becomes harder over time, making it much less flexible. As this change occurs, the lens has more difficulty changing shape, affecting one’s ability to focus on images close-up. The main way to combat this issue is with bifocal eyeglasses or bifocal sunglasses when outdoors.

What Are Bifocals?

For people who already need to wear corrective eyewear, it can be frustrating to switch between two pairs of glasses for different activities. Some people may even juggle around three types of eyewear if they also have a separate pair of sunglasses. Bifocals offer a convenient solution by combining your prescription lenses and reading lenses into one type of eyewear. You can even purchase bifocal sunglasses for optimal vision when outdoors. With bifocal lenses, there is a clear line between a top section that features your prescription and a smaller bottom section that is designed to help you see up-close for activities such as reading.

What are the Differences Between Bifocals, Trifocals, and Varifocals?

When considering which type of eyewear is best for your needs, it can be confusing trying to understand the differences between bifocals, trifocals, and varifocals. As explained above, bifocals are split into the distance and near vision sections with a visible line between them. Trifocals are split into three different points of focus. In addition to a distance and near vision, these lenses have a third section for intermediate vision. People most often use intermediate vision when looking at something about arm’s length away, such as a computer screen. Varifocals, or progressive lenses, also have three regions but without lines neatly separating them. Instead, these lenses change gradually to offer distance, intermediate, and near vision correction.
