What are bifocal glasses?
Bifocals offer clear and sharp vision to both distance and reading without changing glasses.
They
often have a noticeable line diving the two prescriptions.
Did you know?
Bifocals were invented by Benjamin Franklin to address both nearsightedness (myopia) &
farsightedness (hyperopia) in one lens.
How do Bifocal work?
1
Upper Part: The top portion of the lens typically corrects for distance vision.
2
Visible Line: Traditional bifocals often have a noticeable line dividing the
two
prescriptions. This line demarcates where the lens changes from distance correction to near
correction.
3
Lower Part: The bottom segment of the lens is adjusted to aid with near vision tasks,
such as reading.
