Bifocal Lenses

As you age, your eyesight changes and you may require different types of lenses to correct your vision. Bifocals are one type of corrective lens that you can use to improve your vision. Our optometrists at Eagle Vision Eye Clinic in Longmont can help you determine if bifocals are the right lens type for you.

Bifocal Lenses

What Are Bifocals?

Bifocals are corrective lenses that have two different prescriptions in one lens. The top part of the lens is used for looking at distant objects, while the bottom part is used for close-up vision. You can use bifocals to correct several different vision problems, including:


This is a condition that typically affects people over the age of 40. Presbyopia occurs when your eyes’ lenses become less flexible, making it difficult to focus on close objects. This can often be corrected with bifocals.


Astigmatism is a common vision problem that occurs when your cornea (the front surface of your eye) is curved or shaped irregularly. This can cause blurred or distorted vision. Bifocals are often used to correct astigmatism by helping your eyes focus light correctly.


Myopia, or nearsightedness, is a vision problem where your eyes can see clearly up close, but objects in the distance appear blurry. Bifocals can help to correct this type of vision problem by allowing you to see clearly at all distances.


Hyperopia, or farsightedness, is a vision problem where you can see distant objects clearly, but close objects appear blurry. An optometrist can prescribe bifocals to help you see clearly at all distances.

Types of Bifocals

Our optometrists can prescribe a few different types of bifocals, depending on your specific vision needs.

Progressive Lenses

These lenses are also known as no-line bifocals. Progressive lenses gradually change the prescription from the top to the bottom of the lens, allowing you to see clearly at all distances.

Round Seg Lenses

Round seg lenses are bifocal lenses with a round segment at the bottom of the lens for close-up vision. The rest of the lens is used for distance vision.

Flat-Top Lenses

Flat-top lenses are a type of bifocal lens that have a flat segment at the top of the lens for distance vision. You can clearly distinguish the upper and lower parts of flat-top lenses, which some people may find helpful.
