About 64% of people spend 4 hours or more in front of a computer screen. While others spend hours reading books often having small letters.
All these things can seriously test our ocular muscles that need to respond accordingly, adjusting to the distant vision of daylife and near vision of reading and screen time.
So to help our eyes, the new anti-fatigue glasses have to develop that have two functions in one and can benefit people in preventing any symptoms of visual fatigue. So let us see what they are.
What are anti-fatigue lenses?
Anti-fatigue lenses, also known as AF lenses, are a specialized type of lens that has a progressive shift to help in near vision towards the bottom.
The upper end of these glasses provides distant vision necessary for everyday life activities like walking and driving while as you go down the lens gradually changes to the one that is suited to near vision to help those that need to rest their visual muscles. This rest to your visual muscles can help stall any refractive errors that one can expect with increasing age due to the weakness of eye muscles.
These anti-fatigue lenses are slightly different from progressive lenses that are a great 3-in-1 solution. Along with the near and far vision settings you see in anti-fatigue lenses, they also have the middle vision setting.
People often find it tough to adapt to three different settings and initially using them can cause headaches. But using something like an anti-fatigue lens is not only a solution in itself but can also be used as a safe transition to Progressive lenses for people who feel uncomfortable wearing them directly.
However, as time goes on and one gets used to this setting, they become a great solution for people that have one refractive error but another may be developing too (for example a patient of the nearsightedness who is also developing Presbyopia).
Do I need glasses for eye fatigue?
You can use glasses for eye fatigue, or anti-fatigue glasses if you are someone who does a lot of close work like reading or sitting in front of screens. Anti-fatigue glasses are specially indicated if you have normal glasses and feel extremely tired at the end of the day with eye strain.
Long spans of reading or using different devices can considerably tire up our eyes. For this purpose, things like anti-fatigue glasses and blue light protective glasses can be a tremendous solution to protect our eyes from strain.
Computer users that show symptoms of digital eye strain such as headaches, blurry vision, and watery eyes are especially good candidates for anti-fatigue glasses.
Another good candidate is someone called a pre-presbyope. These people show signs that they are soon to have significant near vision decline. These people have weak ocular muscles and anti-fatigue lenses are the perfect solution for these people as it spares their near vision muscles and allows them to rest.
These people could also benefit from progressive lenses and anti-fatigue lenses prove to be a good transition for them as they move towards progressive lenses. Having said all that, it is extremely necessary to consult your doctor before any change in your glasses as it can have considerable medical consequences.
Benefits of Anti Fatigue Lenses:
- They allow you to comfortably see any objects close to you which can be a serious problem for people with near vision difficulties.
- They delay the progression of Presbyopia and are a great option to recommend to Pre-Presbyopes.
- They reduce symptoms of digital eye strain which is a significant risk factor along with blue light for macular degeneration, a common cause of blindness.
- Are easy to adjust to and very few people reject them after starting to use them, unlike progressive lenses.
Anti-fatigue lenses are a great innovation for people who spend a lot of time in front of screens or read a lot. They offer both distant and near vision in one glasses and can reduce eye strain symptoms and help people perform better on their jobs and read with peace.
