I'm in an office with standard Flourescents.
I'd like to find some bulbs (reasonably priced) that will me more natural/less
visually straining on my eyes as I stare at a computer all day.
Can someone make a recommendation?
What type of "standard" fluorescent lamps? T12 or T8? I assume 4-foot.
If T12 are they 40-watt or 34-watt?
They look like 4 foot bulbs.
I can read "34 Watt" off the bulb through the grill.
oh. p.s. I have contacts.. "really incredibly bad eyes".
There is a relation between extended close work (such as stareing at computer
monitors all day) and eye strain. The eye has to focus inward at close
objects, and holding the focus there for long periods isn't easy.
This is also the very common, but not so well known cause of nearsightedness.
It is very stressfull to hold the focus inwards for a very long time, so the
eye actually adapts itself by elongating so that it can view close objects
without any focusing effort. And then your eye doctor gives you
glasses/contacts which when worn for close work undoes the adapation, and
your eyes have to adapt all over again by elongating some more. The process
repeats. The glasses get thicker.
Some things you can do to releave the strain are; 1) People with normal
vision can wear reading glasses to reduce the focusing effort required by the
eye, and even as a nearsightedness prevention. 2) People that are already
moderatly nearsighted can simply remove the glasses/contacts when doing any
extended close work. 3) People that are badly or severly nearsighted can
purchace a weaker prescription (approx. 2-3 diopters weaker) glasses or
contacts that are to be used for any extended close work. The weakness
depends on how far you sit from the monitor or close work so that the eye can
view the close objects without any focusing effort.
On the lighting side of things, it's always a good idea to get rid of the
34w/CW lamps. Talk to your boss or maintenance guy to install 3,000k lamps,
preferably ones that are 40w. Also, offices tend to be lit brightly.
Sometimes simply delamping two of the four lamps in each fixture helps.
