Charting Historical Relevance of Bifocal Contact Lenses

Benjamin Franklin, the first wearer of bifocal contact lenses, is credited by people for its invention. Yes, it seems quite surprising but it’s true. He was suffering from hyperopia and was seeking for a solution by which he will not need to switch his glasses when performing different activities. Working on the same, he invented bifocal contact lenses, a lens with two different focal lengths.

Bifocal and Multifocal lenses

Multifocal/Bifocal Contacts Meaning

Multifocal contacts have two or more powers in each lens. Bifocal contacts are also considered multifocal contact lenses. These contacts are generally made of two types of materials - gas permeable and soft lens materials. Multifocal contacts help in vision correction when people have presbyopia, astigmatism and myopia.

Multifocal/Bifocal Contact Lenses and Astigmatism

Astigmatism is a refractive error of the eye that causes blurry vision. Multifocal contact lenses can become a convenient alternative for astigmatism as compared to toric contacts. For people with high astigmatism, multifocal gas permeable contact lenses can help in correcting vision. You can also choose to use multifocal soft contacts if you have less astigmatism.

Multifocal and Bifocal Contact Lenses and Presbyopia

Presbyopia is an eye condition where one is unable to focus on nearby objects. This is an age-related eye problem, mainly affecting adults above 50 years old. The translating/segmented designs of multifocal lenses are able to help people who have presbyopia. With simultaneous vision designs of multifocal contact lenses, near and distant objects are in focus at all times. It takes some more time to get used to this particular design of a multifocal contact lens.

Multifocal and Bifocal Contact Lenses and Myopia

Myopia is a condition of the eye where distant objects appear blurry. This condition is also known as near-sightedness. Myopia generally develops when children are six to eight years old and it increases gradually every year. Multifocal contact lenses effectively slow down the development of myopia in children. Multifocal contact lenses are as effective as the lenses used for orthokeratology, where the special type of gas permeable lenses are worn overnight and removed the next morning. Multifocal contact lenses for myopia generally have the distance power in the center of the lens.

The Pros and Cons of Multifocal/Bifocal Contact Lenses

Some of the advantages of wearing multifocal/bifocal contact lenses are:

Multifocal contact lenses provide better clarity of vision than most contact lenses.

Multifocal contact lenses help in most cases of astigmatism, presbyopia and myopia.

Multifocal contacts are much better at controlling near-sightedness than the regular single-vision soft contacts and gas permeable contacts.

With multifocal contact lenses, children find it easier to engage in outdoor sports than having to wear heavy bifocal eyeglasses.

You can easily wear non-powered sunglasses with multifocal contact lenses.

People who need vision correction and have an active lifestyle generally tend to prefer multifocal contact lenses.

With multifocal contacts, you will have less eye fatigue while reading.

Here are some of the disadvantages of multifocal/bifocal contact lenses:

Wearing multifocal contact lenses at night can be difficult.

One of the side effects of multifocal lenses is that it can be difficult to differentiate objects from the background when they are of the same colour.

It takes a little time to adjust to multifocal contact lenses.

In low-light situations, you may still need to wear multifocal contact lenses with eyeglasses while reading.

Multifocal contacts do not correct vision for everyone.

Multifocal contact lenses have complex designs and they are expensive.

Multifocal contact lenses can sometimes cause headaches when you frequently have to change focus between the near and distant objects.

Some soft multifocal contact lenses can lead to dry eyes and other eye infections.

How do Multifocal/Bifocal Contact Lenses Work?

Multifocal contact lenses have two main types of designs: simultaneous vision and translating/segmented designs. Multifocal contacts with simultaneous vision designs have two other basic designs - concentric and aspheric. Multifocal contacts work accordingly with their designs.

In the concentric designs of multifocal contact lenses, the centre is mainly for viewing distant objects and the circles around the centre are for viewing nearby objects. Multifocal contacts with aspheric designs do not have concentric circles and the powers gradually blend for nearby and distant objects. In multifocal contact lenses with translating/segmented designs, the upper portion is for distant viewing and the lower portion is for viewing nearby objects.
