In today's hi-tech world the relationship of the eye and the computer screen is becoming a topic of concern in medical fields. Studies have found that up to 70 percent of computer workers worldwide experience symptoms of Computer Vision Syndrome, or CVS.
Unfortunately, Computer Vision Syndrome is not only limited to the adult population. Many children are involved with computers in their school and home environments. Hours spent on computers by children can result in the same vision stresses experienced by adults. CVS in children can have a profound effect on the normal progression of their vision maturity.
Symptoms of Computer Vision Syndrome usually appear after 2 or more continuous hours of work on the computer. Headaches, wandering focus, itchy or watery eyes, double vision, and blurry vision are the most common symptoms. Other symptoms also occur and can even include muscle and joint aches, especially in the shoulders and neck.
Harder to Focus On
CVS results from the affect of the computer screen on the eye. Eyes do not read and process characters on a computer screen the same way they process printed materials. Printed characters have crisp edges and high contrast levels making it easy for the eye to focus.
Characters on the computer screen are less defined. Each character is composed of small dots of light that are bright in the middle and fade towards the outer edges. Just as the images fade, our eyes wander across the characters and have difficulty finding a focal point. We must force our eyes to focus which creates a strain.
When reading printed material the eyes automatically find the RPA, the resting point of accommodation. Once this point is determined the eyes can comfortably read the text. The eye has difficulty relaxing on the RPA on the computer screen. The eye wanders and must be forced back to the focal point. This is the cause of eye tension and CVS.
Computer Reading Glasses Work
Is there help available for Computer Vision Syndrome? Yes! Computer reading glasses can greatly ease the symptoms of CVS. Reading glasses work to reduce eye strain and make it unnecessary to constantly look for a focal point when reading text on a computer screen.
Computer glasses have the added benefit of helping in the workplace. Workers who wear computer reading glasses show fewer mistakes in their work and a marked increase in output. This result is due to less stress caused by vision strain.
One drawback to computer glasses has been the fear that they may resemble safety glasses. This fear can be put to rest. Lenses for reading glasses are placed in fashion forward spectacle frames. This includes reading glass styles such as ½ frames and full frames.
Many people who work with computers regularly usually have several pairs of eye glasses instead of just one. They keep the glasses handy by storing a pair near the home and work computer while also carrying a pair for reading computer screens in department stores or at the library.
In fact some people will have reading glasses stored in every room in the house including the kitchen where so many newspapers are read and the bedroom for reading a book before falling asleep. You can keep a pair in the car too so that you always have reading glasses available no matter where you go.
Flex Vision's range of ultra-slim light-weight reading glasses, spectacles and sunglasses utilise a patented folding temple system that allows them to fold away completely flat. The slender but strong glasses carry case easily fits into your pocket or handbag. To view our range, visit Reading Glasses.

How fast would you have to be travelling for a speed camera to be ineffective?
When you whiz through a speed camera, a speed sensor which works on the doppler principle logs your speed, and activates the circuits or mechanism to snap a picture of your car as it passes through the focal range of the camera.
Now, presumably, if you crank up your speed high enough, you would be able to escape out of the cameras field of view or focal range before the camera got activated.
But what speed would be required to acchieve this?
And would it be possible to travel so fast that the speed detector mechanism doesn't even notice you because you've passed it by before it even had a chance to register your existence?
In theory this would be possible. Much would depend upon where the speed camera was set up. In most cases, you'd probaby need to be moving well in excess of double the legal speed limit at least.
The total reaction time for the typical speed camera system is well under half of a second -- typically 1/10th of a second. Even at 100 MPH, you'll only move a few feet -- 14.6 to be exact -- in 1/10th of a second. Even at 200 MPH, a motorway camera would still have you well in range.
The Greatest Films
The road movie is a well-worn genre with unique plusses and pitfalls. Its usual variety of locations affords flexibility in molding a story, but the focal setting (a car, in most cases) can be limiting. To make something special, any......

Getting excited about reading through much more. Excellent article post. Fantastic.
I simply desired to appreciate you again. I do not know the things that I could possibly have used in the absence of those information shared by you concerning this topic. It absolutely was a very hard situation in my view, but coming across a new expert technique you processed it made me to weep with gladness. Now i’m grateful for the advice and thus trust you are aware of a powerful job that you are carrying out teaching other individuals thru your blog post. Most probably you’ve never encountered any of us.
I have been browsing online more than 3 hours today, yet I never found any interesting article like yours. It is pretty worth enough for me. In my opinion, if all site owners and bloggers made good content as you did, the net will be a lot more useful than ever before.
