EYESTRAIN

SATURDAY before last Saturday I had headache for two days, Saturday and Sunday (parusa). Other than that, my right "bionic" ear, parang may hangin o water siya sa loob and I hate the feeling, so uncomfortable! So I told my mother regarding my situation, then nag-set siya ng appointment to a specialist last Saturday, May 5, 2007.
Upon checking my ear, wala naman daw problema sabi ng doctor, so okay… fine. Then, sinunod naman na i-check ‘yung mata ko. Sabi ko kasi na lumalabo ang nakikita ko. After some test, result… 20/20 vision pa rin ako… thank God, akala ko ire-recommend na mag-eyeglass ako. Then I asked the doctor kung ano ba ang problema sa mata ko at bakit ganu’n na 20/20 vision naman ako, pero bakit sila lumalabo… then she said… EYESTRAIN. And to end this post...

WHAT IS EYESTRAIN?
Eyestrain, an ergonomic problem often related with the use of computers and Video Display Terminals.
The symptoms of eyestrain may be sore, tired, itchy dry or blurring eye, headaches, difficulty focusing between VDT and source documents, blurred or double vision, color fringes / after images and increased sensitivity to light.
.
These symptoms may be caused by;
.
IMPROPER LIGHTING
If the light in the work area is too bright or too dim, the human eye has to work extra hard to compensate for these harsh environmental factors. People may not even be aware that their eyes are under duress, but over time they may develop symptoms of eyestrain.
SOLUTION
Use indirect, ambient lighting and an adjustable light source at the desk, where extra illumination is required.
.
GLARE
Glare can be caused by sources of light such as windows, lamps, or overhead lighting. Look at your monitor screen to see if there are any bright blotches of light. While you may not be conscious of this irritation, it can cause eyestrain over the course of a long day. Glare can also be caused by too much contrast between the screen background and the displayed text.
SOLUTION
Adjust your monitor so that it is not reflecting the light source. Tilt the monitor down so that it doesn't reflect overhead lights, or move it perpendicular to windows. Close shades or blinds if the computer cannot be moved. Move lamps so that they are not reflected directly in the monitor. Use glare screens.
.
EYEWEAR
Many computer users wear bifocals or trifocal lenses fitted for reading print and distance viewing. Sometimes these prescriptions may not be adequate for computer work.
SOLUTION
If you wear glasses of any sort and frequently experience headaches while working at a computer, you should probably check with your eye doctor to make sure you are wearing the correct prescription for such work.
.
VIEWING ANGLE AND DISTANCE
If your monitor is too far away, you will have to strain to read the print. Likewise, if it is too close, you may also strain your eyes. If the monitor is too high, you will have to angle your neck to look up at it, which could cause your neck to be sore, and may contribute to headaches. Also, when you are continually looking up, you may not fully close your eyes when you blink, and this can cause your eyes to dry out.
SOLUTION
Generally speaking, the recommended distance for the monitor is between 18-30 inches from the user, with the first line of text just slightly below eye level. You want the keyboard directly in front of the monitor. If the keyboard/monitor is off to one side, the distance to the monitor may be slightly different for each eye, causing them to focus separately.
.
UNITERRUPTED FOCUS ON THE SCREEN
When people concentrate, they blink less often. Sometimes they concentrate so hard that they blink only once per minute, instead of the normal once every five seconds. This, too, will cause the eyes to dry out and become irritated.
SOLUTION
Take micro-breaks! Frequently look up from your monitor and focus on an object several feet away. Make a conscious effort to blink.
.
VDT AND DOCUMENT HOLDER LOCATION
If the document holder is below the VDT or off to the side, each time your eyes look from one source to the other, your pupils have to adjust. If you have to do this for long periods of time, it can cause headaches and eyestrain.
SOLUTION
Place document holder at the same level, angle, and distance as the screen to avoid having to shift eye focus.
.
DUST ON SCREEN
A buildup of dust on the screen can make it hard to distinguish characters. This may also contribute to glare and reflection problems.
SOLUTION
Dust off your monitor every day.
