What are occupational lenses?
Unfortunately our eyes weren't designed to read for any length of time and this gets increasingly difficult as we get older. After the age of 40 nearly everyone will need reading glasses. However, if we still want to function normally and read, use a computer, whilst being able to peer up and see distance objects like clocks and people's faces, then we need a more advanced lens type. Varifocals were often used for this but they were designed before the internet age. They are great for driving or walking around shopping but as they have little intermediate correction they are not very good for computer use. Therefore, for today's digital world lens manufacturers have come up with "Occupational" or "Indoor" Lenses.
Occupational lenses are a type of varifocal lens that are designed to suit a specific task, such as working at a computer in an office environment.

To overcome this difficulty, the occupational lens, also known as an indoor lens and as a degressive lens, increases the size of the near and intermediate parts of the lens. To do this it usually sacrifices some or all of the distance prescription.
