Nearsightedness which is often caused by too much “near work” (computer, reading, school work, fine handiwork etc), can be prevented or reduced using reading glasses.
In the last 30 years, prevalence of nearsightedness have increased by around 60% and most of that results from poor viewing habits during computer use and schooling.
Even the science series “NOVA” recognize that environment also plays a role in our health.
I have designed a fold-able reading stand to improve your posture and help maintain a good reading distance. Find the free PDF file here: http://www.mediafire.com/?sharekey=30241398a9d7e2c0d1014a7a667fa2b4e04e75f6e8…
Bifocal lenses and reading glasses (aka. plus lenses) are highly effective in preventing or at least slowing the development of nearsightedness. Bifocal lenses work by having reading lenses built into the lower half of regular perscription lenses.

Post a video response with one of your video to make this video more visible!
Incidences of nearsightedness or myopia, has increased dramatically in recent decades.
This increase is caused primarily by excessive amounts of near tasks such as reading and computer use.
This animation provides information on how to reduce and prevent nearsightedness.
Together, we can make a difference!
We would like to design an effective petition to further this cause. I welcome your ideas and request that you post them as video comments. Thank you
