You’ve worn single vision lenses for a while, but your prescription may now include close-vision correction (in your near/ADD box.)
“I’m not ready for progressive lenses yet though?!” I hear you say.
No worries. Anti fatigue lenses are a great in-between option if you want to take the strain off close-vision tasks.
Let’s compare these lenses so you can decide which type is right for you.
Anti fatigue lenses provide two corrective focal powers, whilst varifocal lenses provide three. This is their main difference and what separates them as lens types.
What are anti fatigue lenses?
Anti fatigue lenses primarily aid your distance/intermediate sight in the main upper portion of each lens. However, in the lower portion they also have a close-vision ‘zone’ which eases visual tasks within 30cm such as close reading.
Hence their name, anti fatigue lenses reduce eye strain by providing additional close-vision correction. They relieve the muscular strain in your eyes used to see up close.

What are progressive lenses?
Progressives (varifocals) provide visual correction for close, intermediate and distance vision in one pair of lenses. They give a gradual spectrum of focal power which you can ‘visually select’ to focus near or far away.
The upper portion of a varifocal is used for distance, the middle is used for intermediate distance and the lower portion is used for close reading.
Acclimatising to progressives takes practise, which is why they’re more complex than anti fatigue lenses
Relax lenses are another name used for anti fatigue lenses. They provide close-vision correction in the lower lens portion for close-vision tasks within 30cm. The upper lens portion is for distance tasks beyond arm’s length.
Anti fatigue lenses are good option if you’re 18–40 years old, require near-ADD correction and expereince eye strain from close-vision tasks. They can be worn all day and can reduce digitally induced eye strain from computer work, reading and writing.
In 2021, standard (1.50) index CR39 anti-fatigue lenses cost approximately £120 including anti-glare and and-scratch coatings (HMC).

Hopefully this article will help you weigh up anti fatigue lenses vs progressive lenses for your next pair of glasses.
