This is one of the biggest postural benefits of occupational varifocals as they can prevent the habit of tilting your head to see nearby objects such as your computer screen.Īccording to an article by Ergorisk, long durations of computer work with head-tilt can cause neck or back pain, potentially leading to further muscular implications.
With an enlarged intermediate lens-section, you won’t need to tilt your head backwards to see through the middle or bottom of your lenses for screen work. They have a much broader focal corridor which can help improve your working comfort at your desk. If you regularly work on a computer, investing in computer or office glasses with can help you in a number of ways.Ĭomputer or office progressive lenses are specifically designed to maximise the amount of intermediate lens-area you can see through. Sticking to varifocals, are progressive lenses good for computer work? Any of these options are designed for screen-work to aid occupational tasks.Īs you can tell, computer glasses are a mixed terminology. Single vision intermediate lenses, computer varifocal lenses or blue light blocking lenses. You won’t be able to focus on anything much further than arm’s length, thus making them more limited than office varifocal equivalents.Ĭomputer varifocal lenses are a popular option as they’re more specialised than office lenses for close to intermediate work.Ĭomputer glasses can mean one of three things. Like office lenses, computer varifocals lenses are optimised for reading, writing and computing but are limited to intermediate vision only. In the illustration below, you can see the benefits of a much broader intermediate corridor through occupational lenses.Ĭomputer lenses, also called computer progressives, are a supplementary varifocal lens designed solely for close to intermediate use with no distance vision capacity. This is why occupational lenses are always used a supplementary pair of glasses in addition to ones that can help you with distance viewing. You won’t be able to focus on anything beyond this distance which makes them completely unsuitable for driving.
The drawback of occupational varifocals is they’re limited to a maximum distance vision of about 4m. Specifically, office lenses are optimised for occupational work involving reading, writing and computing. Office lenses, also called office progressives, are a supplementary varifocal lens designed primarily for close to intermediate use with a very limited distance capacity of 4m. In the illustration below, you can see the functional focal area of an everyday varifocal lenses and its relatively narrow corridor.
However, they aren’t so good for occupational tasks as they tend to have quite a narrow intermediate “corridor.” Looking through an everyday lens, there isn’t much lens-space for you to look through when using a computer, reading or writing. They are a “one lens does all” helping you avoid having multiple pairs of glasses.Įveryday varifocals are great for many scenarios, from close-reading notifications on your phone to distance-viewing the road when driving. To help you decide on which lenses are right for you, this article explains the three main types of varifocal lenses you should know about.īanton Frameworks - varifocal glasses | Model E/EL-RD | BLU spectacles holderĮveryday varifocals are used for any of the three vision zones which are defined as close, intermediate or distance. These lenses can be either ‘office’ or ‘computer’ varifocal lenses which differ in their focal capacities.
Occupational lenses is a collective term for varifocals, designed for close to intermediate tasks such as reading, writing and screen-work.
