Computer glasses are an under used component of a comfortable office environment. As a person approaches their 50’s it becomes more difficult to see things not only at near but at an intermediate range as well. Normal progressive lenses let you see objects clearly at this distance but only by lifting your head up to look through the intermediate portion of the glasses. Using regular glasses while working at the computer leads to neck pain, back pain and eye strain. This is where computer glasses come in.
Progressive lenses allow a person over 40 to view objects clearly at all distances, even computer distance. Progressive lenses let us view intermediate objects by looking half way down the lens. With computer glasses; however, you can view an intermediate object by looking straight ahead (most computer monitors are at eye level), and the bottom of the computer lens lets you focus an object at normal reading distance. Computer glasses allow for a natural eye position so you can comfortably view your computer.
If your computer monitor is at eye level, you are in your late forties or older, and spend more than 30 minutes at the computer a day then computer glasses are definitely a worthwhile investment.
Computer glasses are an important part of making your workstation a comfortable place to work. See this article on visual ergonomics for more information on setting up your workstation.
Your eye converts what you see into very low voltage electrical signals that travel along the optic nerve between your eye and the visual cortex. The computer inside the VEP compares the strength and speed of signal to a database of normal results and then the doctor uses that information to guide his or her diagnosis.
As parents we often think that our son or daughter has good vision and therefore does not need an eye exam. Common misperceptions of why eye exams in children are not important include, my son doesn’t complain of blurry vision, my child’s grades are good, or the parents have good vision therefore the kids probably do too.

This weekend Taylor and I went with a group of dads and daughters to see A Christmas Carol in 3D. A popular question was, “so how do they do the 3D effect?”
The last 3D movie I saw used red and green glasses so it was great seeing a 3D movie that did not give me a headache. The picture looked great and the 3D effects were well done, however that’s about it. The chase scenes were way to long and really done mostly to show off the movie’s 3d effects. Jim Carrey was good in his role as Ebenezer Scrooge and the movie stuck to the original book. So the bottom line, it’s not a bad movie as a matter of fact they did a good job, however the only reason to see this movie, is to see the 3D effects.
Some of the vision problems cited in the literature review included undiagnosed nearsightedness, farsightedness, amblyopia, retinoblastoma, congenital defects, and strabismus. The report went on to state that a vision screening was not a substitute for an eye exam and that eye exams from an optometrist or ophthalmologist were a very effective way to detect vision problems in children.

Is it too early to think about what we need to do to get our kids ready for school? One of the most important “school supplies” is your child’s annual eye exam. Over 80% of what a child learns is through their eyes, therefore it is important for our kids to see their very best.
