"Nowadays I easily lost concentration at work. I'm currently working in
the IT industry and need to face the laptop for long hours but I easily
can't concentrate and lost focus followed by headache (left side of the
head) and head become like heavy...maybe this is caused by my
stressful work previously...nowadays, i need to frequently take a break
from my work like every 1 hour coz if I continue to force myself to focus,
I'll become dizzy...
Can anyone here advise what's wrong with me? this prob has been
bugging me for 2 years..."
What the two of you have is Computer Vision Sydrome.
To put very simply, your computer screen is NOT a piece of paper,
but a TV screen, or movie, rolling at a standard 60 frames a second.
Place a table fan between you and the monitor, switch it on, and
you will be able to see the running frames, or flickering.
Your eyes can't really tell the difference, but your brain can.
In extreme cases, such flickering can cause photosensitive epilepsy,
particularly in children.
To lessen this problem, raise your monitor's refresh rate to at least
85 hz, preferably 100 hz. However, I understand that laptops are
preset at 60 hz and can't be adjusted.
Secondly, those who use laptops and LCDs are actually asking
for trouble.
One of the reasons behind your problem
- the flourescent lamp behind your LCD
(and the reason why I always turn the
brightness down to ZERO when using
someone else's computer with an LCD).
" ..... they were going against the expectation
and conventional wisdom that LCD displays
were better than CRTs. "
" A friend of mine develops symptoms similar
to ones I experienced after only about 5
minutes, and he was the one who led me to
the first apparent cause of this: the
fluorescent light used for the backlighting
of the display. "
" ..... many people cannot work continuously
with such a display for as long as they can
with a traditional CRT. Some people feel a
headache after about half an hour of work
in front of an LCD panel, yet they can stay
16 hours in front of a CRT. "
" ..... the same fluorescent light technology
which, I knew, was not recommended for
use as the only light source in offices. "
" Unlike the sun (and other lighting
technologies), fluorescent lights are not
stable, but rather, they are pulsing, i.e.
they go on and off several times per second. "

Thirdly, download FLUX and run it.

My FLUX is set at 5000 K for night, 5,500 K day.
Fourthly, order this and use anytime when needed. It's the
best I have used, really soothes your eyes .

Fifth, increase the size of your fonts. I used Franklin Gothic Medium,
minimum font size 17. You can't set this minimum size on Internet
Explorer, but I am using Seamonkey, much more versatile.

Sixth, you can try Essilor's Anti-Fatigue lenses.

" I think this lens is only beneficial to those who read
or are on the computer a lot.

From her age and your description, it's likely she has thebeginning stages of osteoarthritis.
The cartilage at her knees is wearing away.
Go to any pharmacy, buy :
Glucosamine sulfate/HCL
Chondroitin sulfate
Cod liver oil.
A good brand which combines glucosamine and chondroitin
is Livewell's Osteosamin. Take two caps twice a day with food.
" I have been taking the brand Live-well Ostesamin plus Chondroitin
for the pain and have been on it for the last 3 months or so. The pain,
I notice has reduced. It's better than before however, I still have slight
difficulties walking down the stairs and my knees are creaky too. "

For cod liver oil, the cheapest is Naturalle by Upha, Two softgels
twice a day for a start.
Other natural supplements which can also help are hydrolyzed
collagen, cetyl myristoleate (CMO) and MSM.

You've spelt "penis" with a "3" for the "e" as if it is such anembarrassing thing to describle.
You may have phimosis.
See a urologist.
