The vast majority of people who pose this question are implicitly seeking ways to
prevent their vision problems from becoming worse - which is a much more accurate
way of phrasing that question.
As an anatomical part of your body, your eyes reflect how you live your life.
Spending many hours of work time staring at a screen without respite creates an actual
physiological effect; the ciliary muscles become constantly contracted into their near-
focus state, contributing over time to further development of myopia in those whose
eyesight has already begun to deteriorate.
The practice known as 20/20/20 can be done easily: every twenty minutes, focus on an
object located twenty feet away for twenty seconds.
Spending time outside has been proven to be most effective against myopia.
According to scientists, exposure to natural light triggers a surge of dopamine release in
the retina, controlling axial eye growth.
Two hours daily will make a difference, statistically speaking.
Nutritional requirements cannot be ignored - although not in such exaggerated terms as
the supplement industry likes to suggest.
Vitamins like lutein, zeaxanthin, omega-3, and vitamin A are needed for optimal macula
and retina health.
In other words, eat plenty of green vegetables and fatty sea food because your retina is
essentially brain tissue.
Finally, don't underestimate the importance of sleep. Intraocular pressure varies and
poor sleeping habits often correlate with increased eye strain and dry eye problems.
Reversing myopia or astigmatism is unfortunately one thing you will not accomplish on
your own without medical help.
