이중초점 안경이란 무엇입니까?

Since you may over 40 years old and noticed you’re having trouble reading magazines, restaurant menus, text messages and other things up close. Maybe you have to take your glasses off and you can read, this may be a symptom of presbyopia. Presbyopia is a natural loss of near-focusing ability that makes it hard to see clearly up close as you age.

Bifocal lens is separated into two distinct areas with different prescroiptions. The upper part of the lens is designed for distance vision, which can correct and adjust refractive error such as astigmatism or myopia. And the lower part is for reading or close-up model and correct a refractive error like presbyopia or hyperopia. The first bifocal was actually invented by Benjamin Franklin. He just glued the top half of one lens to the bottom half of another and created what we now call an bifocal glasses.  This very simple type of lens has evolved into into more modern bifocal lenses. The most direct descendant of the Franklin lens is the Flat-top bifocal. These lenses have a very large area devoted to your distance vision, with a smallish insert or segment that allows you to focus on objects up close. The working distance, how far away you can hold something and still be in focus, is fixed with this type of bifocal.

How Bifocal Glasses Work?

A bifocal lens enables seamless transition between distant and nearby focal points, facilitating clear vision across varying distances.

The lower portion of the lens caters to near objects, strategically positioned to align with the natural inclination of individuals to gaze downward during activities like reading, handiwork such as sewing, or engaging with mobile devices for texting. Consider the scenario of perusing a book or meticulously stitching fabric – your eyes instinctively gravitate downward, don’t they?
