What Are Bifocal Glasses?

Vision changes seem to be related to age. Presbyopia occurs in the middle age of one person, affecting your eye’s ability to focus. But it can be caused by bifocal glasses.

Bifocal glasses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).

Bifocal glasses were invented by Benjamin Franklin, who solved his own vision problem by taking the lens from his reading glasses and distance glasses and cutting them in half. Then remade the cut lenses into a single pair of bifocals and put the distance lens on top and the reading lens on the bottom.

However, the bifocal glasses come with some problems. So, in the following section, we will show you some common bifocal glasses problems.


What Do Pinhole Glasses Do?

Pinhole glasses are often used by eye doctors who use them as a diagnostic tool to quickly check for vision impairments. Of course, pinhole glasses are sometimes used to treat nearsightedness or astigmatism. Pinhole glasses are also used in conjunction with an occluder, an instrument used to cover one of your eyes while you read an eye chart. The occluder is solid, while the pinhole glasses have a number of tiny pinholes. So, the doctor often uses it to check the potential of your vision.

Pinhole glasses are often used to check corneal distortion and cataracts. A cataract evaluation includes focusing light in the eye to check if vision capability behind the cataract makes it worth performing surgery.

What are browline frames?

The name browline comes from the design of the frame. The upper part of the frame is thicker than the lower part so that the wearer's natural eyebrow line can be noticed. The top is usually made of acetate or plastic, and the bottom of the lens is wrapped with a thinner wireframe. Later, the browline frames have also been modified to meet the needs of more customers. Some browline frames use nylon wire instead of metal wire in the lower part, while the browline frames with metal wire are more durable and stable. If people with high myopia want to have a pair of half-rim glasses, browline frames are a good choice.
