Bifocals: How do they work?

Bifocal sunglasses are prescription sunglasses for those who need vision correction. Bifocal sunglasses are different from single vision lenses, as they have two corrective lenses on each side of the glasses.

There are actually a few different types of bifocals available. Only a medical Ey professional will be able to tell you which type would be best for you. Bifocals are designed to make all activities easier, not just reading. This includes computer use, writing and anything that uses the close range focus, including newspapers and reading signs.

Bifocals contain an actual line across the middle of the lens, which separates the two focal parts. Your Optician will work with you to decide which shape should be used for the near vision focal segment. A half-moon or circular shape is commonly used.
