If you’re in your mid-40s or older, you’re probably wearing glasses with multifocal lenses, like bifocals or trifocals. They have two or three prescriptions to fix your vision. In the past, you might see the line between the two parts of this sort of lens. But now they always look seamless.
- Bifocals – The most popular multifocal form. The lens is divided into two parts. The upper portion helps with vision distance. The lower half is close vision. They are usually prescribed by people over the age of 40 who can no longer concentrate well. This is due to presbyopia, an age-related alteration that affects the lens of your eye.
- Trifocals –These are bifocals of the third section. It lies above the bifocal part of the lens. You’re looking through it to see things beyond the scope of your arm, like a computer screen.
There are also progressive lenses that don’t have a line, start with your prescription distance at the top, and gradually work towards your full reading prescription at the bottom.
