At Texas State Optical-Stone Oak our eye doctors take extra time to determine exactly the correct prescription for your computer needs. Questions you may be asked to assist us in determining your custom prescription lenses include: “How far away is your computer monitor?”, “Do you use one or more monitors at the same time?”, “Do you need to read print up close when using your computer?”, “How many hours do you use the computer daily?” and “Do you need to see far away while using your computer?”.
Besides designing your custom lenses we also recommend anti-reflective coating that blocks some of the blue light your monitor emits and causes eye strain. We take your computer eyewear needs seriously at TSO-StoneOak!
Computer screens are generally positioned in what is considered your “intermediate” zone of vision, which is roughly 20-26 inches from your eyes. Traditional eyeglasses and bifocals are designed to help with close and distance vision, but are not meant to make intermediate viewing of the type required by computer work comfortable. This often leads to blurred vision, eyestrain and headaches after extended computer use. Even trifocals and progressive lenses, which do have areas for intermediate viewing, do not have a large enough intermediate area to make extended computer viewing comfortable. This causes those with trifocals or progressive lenses to bend their necks and backs into less comfortable positions to keep the computer screen in the intermediate area of their lenses, adding neck and back pain to the already bothersome list of symptoms.
By contrast, computer glasses are made specifically to help your eyes focus at this intermediate range, making computer viewing over an extended period of time more comfortable.
Another thing that makes computer viewing uncomfortable, and even potentially sight-threatening in the long run is something called “blue light,” which has been known to cause eyestrain, headaches and fatigue. Recent studies also point to growing evidence that blue light exposure has the potential to increase a person’s risk of macular degeneration over time.
Often computer glasses are equipped with special coatings that help cut down on the amount of blue light that reaches your eyes, such as HOYA Recharge, a cutting edge reflective coating designed to reflect around 30% of harmful blue light away from the eye. This makes extended computer use more comfortable and reduces the risk of developing macular degeneration in the future.
