The nice thing about learning how to choose bifocal eyeglasses is that you are going to find that the process of selecting a pair of bifocal eyeglasses is both interesting and fun. Most of us want to wear bifocals because the same pair can help us see things better at a distance and they also help us to read without any difficulty. There are several types of lenses to choose from which is why it pays to find out more about how to choose bifocal eyeglasses.

Select a suitable frame

Start by selecting a frame. If you are ordering new lenses, then be sure to take your existing pair of eyeglasses with you to the optician so that they can find suitable lenses for your eyes. It is also important to ask your optician about how to wear the bifocals. There are a variety of bifocals and lens types that are used for different purposes.

Lens segments

Bifocals normally have a lens segment at the bottom of the lens that in turn can be of different shapes. The flat-top segment (standard segment) is shaped like a half-moon while the ground segment, as well as the executive segment, cover the entire bottom portion of the lens.

Standard bifocals

It is also important to pick standard bifocals for reading. You can choose the standard flat-top which is available in various widths spanning everything from twenty-five millimetres to twenty-eight millimetres to thirty-five millimetres. The flat-top segment also has a line across the top which you have to look through in order to change the focus from distance viewing to reading power.

If you are primarily going to use your bifocals for long-distance viewing then you should choose bifocal eyeglasses which are both smaller in size and which also use round segments. Round segment bifocals are not as common today as they once were but even so, they are very useful for those who want to work in the outdoors and who are working at jobs that do not entail much reading work.

The round segment bifocal glasses sit in the bottom part of the frame and they allow you to use almost all of your peripheral vision to view objects at a distance. You can also think about using specialty bifocal lenses, especially if these suit your main activities. So, if for example, you are working in front of a computer monitor or if you have lots of reading to do then you should go with bifocals called the Double Ds. These have bifocals at the lower end as well as the top end of the lens. Double-Ds can be bought as bifocals as well as trifocals.
