Understanding The Multifocal Lens

We all know the importance of annual eye screenings for optimal eye health, but how much do you know about the corrective eyewear available to help you achieve clearer vision? During your annual eye exam, selecting the right lens and coatings is just as critical as selecting the right pair of frames.

Near or far, personalizing your lens can make a huge impact on the way you see and the things you do. And thankfully, today’s latest lens technology not only offers you custom vision– it adapts to your lifestyle so you can always find the perfect lens that can keep up with your daily frenzy.

Before making any eyewear purchases, you’ll want to know what options are available for your eye needs:

Single Vision Lens vs. Multifocal Lens:

Single Vision Lens— these lenses are prescribed when you need correction for one field of vision, either for distance, computer, or near vision. Single Vision has the same optical focal point or correction over the entire area of the lens.

Multifocal Lens— after the age of 40, some of you will begin to experience the symptoms associated with presbyopia. If you already wear prescriptions eyeglasses, this usually means you will need to use multifocal lenses to continue to see clearly. Multifocal Lens contain two or more lens powers to to help you see objects at all distances after you lose the ability to naturally change the focus of your eyes due to presbyopia.

Types of Multifocal Lens:

Bifocal Lens— contains one straight visible line that defines the optical focal point between distance vision and near vision.

Trifocal Lens— offers a third focal point in the middle of the lens to view intermediate distances that are not covered by the top or bottom correcting segments. This lens type has two segment lines.

Progressive Lens— eliminates segment lines for a smooth transition between correcting segments. While progressive lens are more popular, conventional bifocal and trifocal lens offer a wider lens area for reading and computer work in comparison to progressives.

They type of vision problem that you have determines the type of lens. Thankfully this doesn’t mean having to take off one pair of glasses to put on another.
