Eye strain and eye fatigue result to many complications from serious to less serious, if any of them remains to be a continuous problem.
When we check online articles about the two topics, we will often find them associated with each other as a single unit of idea. Eye strain would be commonly defined as fatigue of the eyes due to excessive use of visual catalysts like the computers.
The American Heritage Dictionary defines it as pain and fatigue of the eyes, often accompanied by headache, resulting from prolonged use of the eyes, uncorrected defects of vision, or an imbalance of the eye muscles. We can derive here that eye strain is fatigue itself.
Some sources indicate that eye fatigue is “asthenopia” itself. It is a condition normally experienced by people whose work requires extended visual concentration (MD Guidelines).
Medical sources say that Axtaxanthin is a highly effective cure for asthenopia or fatigue. Axtaxanthin is an antioxidant or a carotenoid (dark colored dyes found in plant foods) in the class of plant compounds that actually “work by improving blood flow to the muscles that control accommodation in the eye, as well as to the small blood vessels in the retina.” (Deborah Mitchell, Phoenix Alternative Medicine Examiner)
Some studies say that fatigue is characterized by the muscles becoming tired in a similar context as other muscles in our body. Once these muscles tire, the symptoms start to occur. While eye strain is basically characterized by dry or watery eyes, blurred vision, and headache; eye fatigue is characterized by almost the same symptoms as eye strain but added with burning or tired sensation in the front of the eyes, headaches, and an overall feeling of tiredness. Eye fatigue can lead to more serious eye complications such as Glaucoma, or loss of sight. Eye fatigue serves as an early warning sign of glaucoma unless otherwise treated.
With this information at hand, we will be able to derive what some reports say, that eye strain is not a serious eye problem but eye fatigue is. Both can be corrected and prevented. But irresponsible handling and personal negligence of both can lead to step-by-step complications like myopia, cataracts, glaucoma, etc.
Some sources also differentiate the two as separate entities. They are recognized as two different ailments acquired by heavy computer use. Many studies reveal that fatigue symptoms are easy to spot but serve as warning signs for glaucoma or blindness, as mentioned previously. Strains, however, is the less complicated and less dangerous compared to fatigue. They can be compared and contrasted with a thin line to tell the difference between them, but for sure, they both need enough attention and proper handling to avoid damaging ones eyes. It is very important that we value and take extra care of them. It lights up our whole body, making us effective and successful workers and persons.
