Tips for Eye Care

With so many of us spending lots of time in front of the computer every day it comes to no surprise that research is showing a rise in visual problems. What can one do? First, it's important to find out how you can protect your eyes through eye health exams and by making a few minor changes in your computer viewing habits.

 



Here are some helpful Eye Care Tips 

Positioning is everything

Correct positioning of your computer, keyboard and typing copy is essential. Your screen should be positioned about an arm's length from your eyes and 20 degrees below eye level. Consider foot and wrist rests for added comfort.

Lighting can make all the difference

Room lighting should be diffuse, not direct, to reduce glare and reflections from your screen. Look into an internal or external glare screen and be sure to set your colour, contrast and brightness levels to suit you.

A little extra help for your glasses

Anti-reflective coatings on the lenses of your glasses can be applied by your optometrist to reduce discomfort and to ease reduced vision from bright and/or flickering light sources such as VDTs and fluorescent lights. And don't forget, your doctor of optometry can talk to you about eyeglasses designed specifically for people who use computers a lot.

Take time out, our 20-20-20 rule

Step I :-
After every 20 minutes of looking into the computer screen, turn your
Head and try to look at any object placed at least 20 feet away. This
Changes the focal length of your eyes, a must-do for the tired eyes.

Step II :-
Try and blink your eyes for 20 times in succession, to moisten them.

Step III :-
Time permitting of course, one should walk 20 paces after every 20 minutes
Of sitting in one particular posture. Helps blood circulation for the entire body.

It's all in the blinking

Did you know that on average we blink 12 times per minute? But wait, did you know that when we're on the computer we only blink 5 times per minute? That can add up to dry eyes. Relieve the discomfort by using artificial tear drops or gels and remember to blink!

Palming

Sit straight at your workstation and rub your palms against each other till you feel them warm. The warmth of your palms helps soothe and relax tired eyes. Then, lightly cup your eyes with your palms and relax for 60 seconds. Count the seconds in your mind. Repeat this exercise two to three times whenever your eyes feel tired, or as often as you want. While palming, you can either rest your elbows on your desk or keep away from the desk and cup your eyes. Both ways are fine.

Splash water on your face

During breaks, splash water on your face while closing your eyes. This has an overall relaxing effect and helps you feel refreshed.


Use tea bags

Keep two used tea bags in the refrigerator before you leave for work. Once you are home, place the tea bags on your eyes for a few minutes as you relax. This not only soothes tired eyes, but also reduces puffiness.

Eat healthy
 
Incorporate Vitamins A, C, and E on a daily basis; eat citrus fruits, green leafy veggies, tomatoes, spinach, poultry and dairy products. Pack a box of chopped carrots, cucumber and fresh fruits and munch in-between meals at the office.

IBM Watson Jeopardy analysis, computer wins over humans

IBM Watson Jeopardy analysis, computer wins over humans. The Jeopardy! Showdown has a lot to talk about. Reports have surfaced that the showdown that has grabbed headlines for reasons that humanity was pitted against IBM’s Watson supercomputer did not go so well. 
The carbon-based life forms, Ken Jennings and Brad Rutter were not so successful to defeat the system. The IBM machine was at the centre of attraction. The three-part Jeopardy tournament is withdrawing huge crowd. Everybody wants to see who wins in the fight between machine and humans.
For many the show that is being aired this week on American televisions is the talk of the town. Watson was quick to react to the buzzer even than Jennings’ reaction that too after being known that the legendary is faster than most humans.
It is another story that on the trivia game show, he was able to rack up a 74-game winning streak. But it was only once. It would be interesting to see whether he would be able to repeat it again. If he does so then it would be in many ways an achievement. All eyes are on him. Will he be able to repeat the feat again? This and other questions are being debated by watchers and experts. 
When round one ended on 18th Feb, 2011, Jennings had $2,000 and Watson had $5,000. Rutter too was able to pull some. When the round two started it was difficult to predict anything. Watson was bang on target as he was able to answer 13 of the first 15 questions. Jennings also did the best. However, all three contestants answered one incorrectly.
