What are multifocal or another name for it, progressive lenses? It is basically glasses that have lenses that contains more than 1 prescription, it actually contains 3 prescriptions. It has a close-up vision, middle-distance vision or a distance viewing vision.
Multifocal lenses are an updated version of the bifocal and trifocal lenses. These lenses have telltale lines in the lenses while multifocal lenses has a more seamless look. Another problem that arises with bifocal lenses is that due to it only having two prescription which are close-up and distant vision, the wearers get unclear vision. This is because when the wearer looks at something at a middle distance, their vision is unclear as there is no prescription for middle vision.
Let’s talk more in-depth about the prescribed visions. For the close-up vision, it is usually for reading, sewing or anything that needs a closed-up look at something. For middle-distance vision, it benefits the wearer with the ability to see things that are of reasonable distance like looking at the computer, cooking and such. For the distance vision, it is best suitable for when the wearer is driving. watching television and such.
Now that we know what multifocal lenses are, who needs them? Well, anyone who has a vision problem can wear these lenses but the norm is usually those who are the age of 40 and above who has blurred vision when looking at closed up things would need them. This eye condition is called presbyopia. It is just another wonderful part of growing older and wiser.
But, that is not all, even if you are over the age of 40 and is nearsighted or short-sighted, you can still develop this eye condition is which your close-up vision range is slowly becoming unclear.
