Overnight Vision Correction is a new treatment for short-sightedness which does what it says - it corrects this widely prevalent vision problem overnight while a person sleeps. But equally important in today's screen-dominated environment where too much of our lives is spent staring at computers, TVs and smartphones, this new treatment could help the millions of people who suffer from what optical experts have now termed ‘Computer Vision Syndrome' (CVS). Human eyes do not handle extended computer screen viewing all that well, especially if they are viewing through daytime contact lenses. "Your eyes are happiest when used for a variety of tasks utilizing a variety of focal distances with a variety of properly aligned light sources," states Jeffrey Anshel, author of ‘Visual Ergonomics In The Workplace'. "Computer use provides none of the above."
Eyestrain, blurred vision and headaches from computer use can be greatly exacerbated if the computer user is a daytime contact lens wearer. The constant short focusing distance typical of computer users and the greatly reduced blink rate from constant staring (as much as eighty per cent) combine to create a range of eye health problems which are increasingly being reported from the workplace. Foremost amongst these is the complaint of dry, irritated eyes which can often mean that daytime contact lens wearers are forced to switch to glasses at the end of each day for comfort reasons and in some cases give up daytime contact lens wear completely. However, with Overnight Vision Correction , small custom-designed corrective lenses are only worn while sleeping so there is no need for contact lenses or glasses during the day.
CVS is now regarded by health authorities as far the most prevalent workplace problem which affects around ninety percent of computer users who work more than 3 hours per day on the computer. And the seriousness of the problem can be gauged by the fact that short-sightedness combined with the eye health issues which CVS gives rise to may lead to sight-threatening conditions like glaucoma in later life. A further key factor is the low quality of indoor light combined with the poor quality of light emitted from computer screens. Anschel says: "It's like you're looking at a light bulb for hours on end - today's LCD screens are almost all backlit with fluorescent light, which is harsh on your eyes." By switching to Overnight Vision Correction , the daytime contact lenses which exacerbate the dry eyes caused by CVS can be thrown away - and there is no need for ‘geek' glasses either!
