Bifocal lenses are an excellent option for people who need near and distance vision. They are also helpful for people with presbyopia or progressive farsightedness, which is the natural aging of our eyes as they become more distant over time. Please read on to learn more about bifocal lenses.
What are bifocal lenses?
Bifocal lenses are lenses for people with nearsightedness or farsightedness. They provide two to three grades of magnification, and are available as one pair with a thinner section (for near vision) and a second pair with a thicker section (for distance). These lenses come in various strengths and are available for both daily wear and for night wear. Because bifocals are designed to be used for distance and reading, the thinner lens is typically designed with thicker sections for near vision to ensure that your eyes are in their best focus for near vision.
These lenses come in two to three grades of magnification. This means that bifocal lenses are generally suited for those who are near and far sighted, but not for people with intermediate vision, as intermediate vision is typically solved by reading glasses.
How do bifocal lenses work?
Near vision – The thinner lens for near vision is designed for maximum near vision to ensure that your eyes are in their best focus for near vision. Because near vision is blurry unless you wear your glasses, bifocal lenses are particularly helpful for people who are nearsighted and want to be able to see clearly without glasses while also wearing glasses for distance.
Distance vision – The thicker lens is designed for distance vision to allow you to see clearly at greater distances without your eyes need to be in the best focus for near vision.
This feature is particularly useful for patients who have farsightedness and want to be able to read books and see distant information without glasses.
Which type of bifocal lens is best for you?
Bifocal lenses come in a variety of strengths and are available for both daily wear and night wear. While generally better suited for distance and reading, daily lenses are less likely to cause mild astigmatism than nightly lenses, which can cause astigmatism more often. Also, bifocal lenses are usually very safe to use and offer the benefits of wearing corrective eyeglasses without having to constantly change lenses.
Because bifocal lenses are designed for distance and reading, the thinner lens is typically designed with thicker sections for near vision to ensure that your eyes are in their best focus for near vision. This is true regardless of which lens you wear for distance.
However, some people prefer to use the thinner lens for near vision because it makes reading easier and provides a slightly wider field of view for near vision.
Bifocal Styles and Brands
If you wear bifocal eyeglasses, you can also try out bifocal sunglasses. Bifocal sunglasses are similar to regular sunglasses except that they have a thin clear lens for distance vision and a thicker lens for reading. Bifocal sunglasses are generally less likely to cause mild astigmatism than regular sunglasses. Bifocal lenses are also available in sunglasses and clip-on lenses.
If you’re looking for a pair of everyday bifocal lenses, you may want to consider daily bifocal lenses. Daily bifocal lenses are designed to be more comfortable and less likely to cause mild astigmatism than standard bifocal lenses. Daily lenses also tend to be more affordable than extended-wear bifocal lenses.

Conclusion
Bifocal lenses are an excellent option for people who need a high degree of near and distance vision. Bifocal lenses are also helpful for some people with presbyopia or progressive farsightedness, which is the natural tendency of our eyes to become more distant over time. Bifocal lenses come in a variety of strengths and are available for both daily wear and night wear. They’re relatively safe to use, and they provide the benefits of wearing corrective eyeglasses without having to constantly change lenses.
Bifocal lenses are available in a variety of styles and brands, and they’re relatively inexpensive compared to other types of corrective eyeglasses. Depending on your needs, bifocal lenses may be an excellent option for you.
