Ever had problems looking at the computer with your reading glasses? Or having a pair of glasses for looking at the computer but having difficulty looking at documents? Or maybe you already have a pair of progressive lenses but it's just so difficult to do computer or near work with it! Read on...
There is actually a solution - office lenses! These lenses allow you to have clear vision across the different distances of different objects on your desk!
Actually, there is no one fixed name for these lenses - office lenses, computer lenses, workspace lenses, etc - they all mean the same thing. For this article we will just refer to them as office lenses.
TLDR Summary: Office lenses let you see intermediate and near clearly; they are like progressive lenses but without the distant-vision area.
HOW DOES IT WORK?
The lenses are split into two parts - the top half is for intermediate vision, and the bottom half is for near vision - however there is no 'jump' from one part of the lens to the other; rather, it is a gradual progression, much like a progressive lens.
Intermediate vision includes things that are about 1-2 metres away - like your computer screen; while near vision includes things that are just in front of you or in your hands - like your mobile phone or a document you're writing.

HOW IS IT DIFFERENT FROM PROGRESSIVE LENSES?
Office lenses function quite similarly to progressive lenses - both of them have a different powers in a lens. However, office lenses are only suitable for intermediate and near vision, whereas the more common progressive lenses are used for distant vision as well.
WHY OFFICE LENSES INSTEAD OF PROGRESSIVES?
By having only the intermediate and near vision portions, the respective areas become larger. A common issue with progressive lenses is that the computer region is not easy to access, and the reading area can be quite restricted since it is all the way to the bottom of the glasses. Office lenses solve this problems with a larger area for both looking at the computer and for reading (near work) hence giving much more comfortable vision.
WHY OFFICE LENSES INSTEAD OF READING GLASSES?
Traditional reading glasses are made for - as the name suggests - reading. Which makes them excellent for things that we hold in our hands, like a mobile phone or a book. However things that are further away, like the computer screen or a calendar placed across the desk is blur. Office lenses allow for a larger range of clear vision compared to traditional reading glasses - so that you have a larger working area.

IS THIS LENS FOR ME?
This lens is ideal if you spend a significant amount of time continuously working on intermediate and near tasks, for instance moving between printed documents and the computer, or monitoring a large screen a couple of meters away while writing on documents in front of you.
This lens is not suitable if you also need excellent vision at further distances, for instance looking at a screen across a lecture hall or at something several metres away. In these situations, a progressive lens would work better as they allow for both distance and near viewing.
WHAT IF I AM NOT PRESBYOPIC / UNDER 40 YEARS OLD BUT I FEEL TIRED DOING NEAR TASKS? CAN I USE OFFICE LENSES?
There are lenses that will help to correct your distant vision, but have a small "addition" at the bottom that helps in near tasks like reading to reduce the eye fatigue. These 'anti-fatigue' lenses help to take off some of the effort your eyes put in to focus at something near, hence reducing eye strain.
In this case there should not be a specific need for office lenses since the anti-fatigue lenses may very well solve the problem.
P.S. We may be spending much more time with near tasks (e.g. we may have used to look out of the window in a bus 20 years ago, but we are probably all looking at our mobile phones today) hence there is a higher prevalence of people complaining about eye strain.
WHAT ARE SOME BRANDS AVAILABLE?
The common brands of office lenses includes Crizal Varilux Computer, Hoya Lecture / TACT, and Zeiss Office Lens Plus / Superb.
Between these lenses there are different intermediate distances - hence a good understanding of your workspace and visual requirements is necessary for these lenses to work perfectly for you!
Before going for such lenses, it is important to take note of your daily routine and how your current glasses are working for you:
- Are you generally deskbound or do you need to move around frequently?
- Do you find that you need a larger visual workspace than what your reading glasses can offer you?
- Do you have difficulty trying to access the computer and near regions of your progressives?
