Trifocal Lenses Solve Many Vision Problems

0 commentaires

As they grow older, many people notice age-related vision problems that are normal. Even though it may be somewhat frightening to individuals, such vision changes are not usually a sign of a serious problem. However, it can be frustrating when one cannot see well enough to read or drive. Fortunately, trifocal lenses are available for individuals who need three different powers in one lens.


Benjamin Franklin, in the 1780s, invented something called bifocal lenses. Before that, those who needed such devices found it necessary to use 2 different pairs of glasses. The condition causing one to need a bifocal lens is called presbyopia. The first bifocal model was designed with a lens that featured a line across its width. The bottom portion was considered the reading lens, while the top section was used to see far away.


As individuals age into their 50s, presbyopia sometimes develops in such a way that it affects the intermediate vision, as well as distance and reading vision. With the help of a bifocal lens, the wearer can see far and near, but his or her arm’s length vision remains blurry. In the 1940s, trifocals were invented, thus solving this problem.


Trifocals feature a 2nd lens section over the close-up vision segment in a long distance lens. This gives the lens three distinct powers. Therefore, it allows individuals to see clearly in three fields of vision.


There are two types of modern trifocals. These styles are referred to as flat top or executive. The latter features ribbon shaped segments with lines through the lens’ width. Flat top models are unlined and feature round sections. Numerous consumers like to wear models that do not have the telltale bifocal line.


Modern technology has also made it possible to develop a broad range of trifocal contact lenses. The benefits associated with contacts of this type are the same as the aforementioned glasses. Ultimately, those who have vision problems associated with aging should discuss trifocal lenses with their optometrist.
