I’m not sure as to the correlation but, somehow, my dreams this morning went from alien invasion to prescribing computer glasses. I was tossing and turning early this AM and dreaming wildly. I recall sitting in a bar ( a place I rarely, rarely, sit) and, much to the dismay of the bartender, ordered a water. While sitting there and noticing floating particles (similar to those found in lemonade) in my water, I looked out the large window and saw space suit clad men running from alien-like men who were shooting laser guns at them. I wasn’t terrified, however, so we can’t classify this as a nightmare, but, when I was younger, nobody told me that, at forty-five years old, I would still be having dreams about invading aliens. I just didn’t see that coming.
Anyway, the dream continued as I left my bar seat and joined the panicking population of humans in their flee from invading laser-bearing aliens. I remember being cornered behind a tree with an incoming attacker, my doom a certainty, when I changed dreams.
I flashed to my office examination room, there was my father, Dr. Sy, and he was telling me how to properly prescribe computer glasses. (This is just as hard to believe as aliens invading earth-just kidding Dad) Anyway, lets talk about computer glasses for a moment.
Computer glasses are prescribed so as to perfectly focus your eyes at the exact distance of your computer screen. This is most important when dealing with patients over the age of 40. Many patients wear no-line bifocals (progressives) or simple bifocals, or single vision reading glasses. Many issues arise when wearing these “non-computer” prescriptions. Basically, the lenses are typically focussed for a normal reading distance of 16″-18″. The computer screen is typically 22″-24″ and thus not in perfect focus. The result is the patient must move closer to the monitor for better clarity, or raise their chin in an exaggerated fashion to utilize the bifocals. All in all, the patient is forced to sit in an awkward manner, causing strain, fatigue, and ”too close to the screenitis.”
Progressives (no-line bifocals ) do focus at the correct distance through proper head alignment, however, the head must be held at a very specific orientation for long periods of time. This can result in head and shoulder pain, as well as eye strain and fatigue.
Computer glasses also have special “anti-glare” coatings and tints which soothe the eyes while “locked in” on that screen for hours at a time. The proper computer prescription is fantastic to those who sit in front of the screen all day long. They can move their head all around and always see clearly, their eyes don’t need to use muscles to focus, glare is reduced and the screen is soothing to view. The most frequent comment made by those who switched to computer glasses is that they can now use their computer for hours on end and feel great at the end of the day. Before, they experienced fatigue, headaches, and mostly, eyestrain. They needed multiple breaks, their eyes “burned” and they couldn’t wait to get off the computer.
So, reflecting back on this blog, we’ve discussed two things that can ruin your whole day: an alien invasion and eyestrain in front of the computer. At least one can be prevented for sure.
