With so many of us using computers at work, computer eye strain has become a major job-related complaint. Studies show that eye strain and other bothersome visual symptoms occur in 50 to 90 percent of computer workers.
These problems can range from physical fatigue, decreased productivity and increased numbers of work errors, to minor annoyances like eye twitching and red eyes.
1. Get a comprehensive eye exam....
Having a routine comprehensive eye exam is the most important thing you can do to prevent or treat computer vision problems. If you haven't had an eye exam in over a year, schedule a visit with an eye doctor near you.
According to the National Institute of Occupational Safety and Health (NIOSH), computer users should have an eye exam before they start working on a computer and once a year thereafter.
During your exam, be sure to tell your eye doctor how often you use a computer at work and at home. Measure how far your eyes are from your screen when you sit at your computer, and bring this measurement to your exam so your eye doctor can test your eyes at that specific working distance.
2. Use proper lighting.
Eye strain often is caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting. When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices.
Eliminate exterior light by closing drapes, shades or blinds. Reduce interior lighting by using fewer light bulbs or fluorescent tubes, or use lower intensity bulbs and tubes. If possible, position your computer monitor or screen so windows are to the side, instead of in front or behind it.
Many computer users find their eyes feel better if they can avoid working under overhead fluorescent lights. If possible, turn off the overhead fluorescent lights in your office and use floor lamps that provide indirect incandescent or halogen lighting instead.
Sometimes switching to "full spectrum" fluorescent lighting that more closely approximates the light spectrum emitted by sunlight can be more comforting for computer work than regular fluorescent tubes. But even full spectrum lighting can cause discomfort if it's too bright. Try reducing the number of fluorescent tubes installed above your computer workspace if you are bothered by overhead lighting.

Anatomy Of Attraction: The Science Behind Love At First Sight
Ever wonder about the meaning behind the phrase "the look of love"? When you're gazing into your partner's eyes, pay some thought to the science behind love at first sight.
The connection between eyes and love is well-documented in poem and prose since time immemorial, the stuff of whimsical fairytales and heroic legends. But while beauty may be in the eye of the beholder, evidence increasingly suggests our brains ...are hardwired to both display and notice visual "clues" when it comes to a potential love interest.

One such indicator of visual attraction is larger pupils. Studies show that our pupils dilate when we feel excitement and attraction. When our gaze falls on a person or object of interest to us, the brain releases a surge of dopamine (a chemical messenger that helps control the brain's reward and pleasure centers), which triggers pupil dilation.
Men perceive women with larger pupils as more romantically appealing. A 2007 study published in Hormones and Behavior showed that a woman's pupils dilate the widest during ovulation. From a biological perspective, because this characteristic is developed under the influence of estrogen, it signifies youth and therefore fertility. Research suggests that men instinctively use such indicators, among other visual cues, to assess the "value" of potential partners — as a way to seek fertile and healthy mates.
Similarly, researchers at Edinburgh University found that women at their monthly fertility peak are most attracted to men with larger pupils. According to the study published in the journal Personality and Individual Differences, larger pupils signal a man's interest, and therefore he is more indicated as a partner because interest is mutual. Conversely, the study found that when women are not at their most fertile, men's pupil size make very little difference when looking for a mate.
Lingering eye contact also is a strong indicator for a potential love match. A 2009 study published in Archives of Sexual Behavior found that a man who rated a woman as attractive held eye contact for an average of 8.2 seconds, which increased his chances of "love at first sight," researchers said. If a man's gaze was around 4 seconds, the research suggests he was less than impressed.
When it comes to eye color and attraction, green eyes are seen as most attractive, according to an AllAboutVision.com eye color poll of more than 70,000 people. But when it comes to matters of the heart, research suggests most people do not have an eye color preference. In fact, it appears "the look of love" is all about the pupils.
So on February 14th, look into your Valentine's eyes — chances are his or her pupils will be dilated! — A.S.
