According to the American Optometric Association, 175 million people use a computer every day, including 61 million children. While computers enable us to be more efficient and more productive, this can come at a price. Computer Vision Syndrome (CVS) is a condition that can occur in individuals viewing a computer screen as little as two hours per day.
We recommend if you view a computer screen two or more consecutive hours per day to be tested. Due to the soft edge of light pixels, these images can be very difficult for our eyes to maintain proper focus, leading to eyestrain.
Symptoms of CVS include: Eyestrain, headaches, slow focusing near and far, tired eyes, burning eyes, blurred vision, and neck and shoulder pain. These symptoms can be alleviated and even avoided if proper eyeglasses are prescribed.
There are two basic types of computer lenses available. Single vision lenses are usually chosen for individuals under the age of 40. If one is over the age of 40, presbyopia is usually a factor and an occupational progressive lens, like Compuclear, may be a better choice.
These lenses have an enlarged intermediate zone at the top of the lens, allowing for computer use without the need to tilt the head. This can help to alleviate back and neck strain along with reducing visual fatigue.
All computer lenses should be reflection-free. Anti-reflective treatment is added to the lenses to allow 99.5% of light to be transmitted through the lenses. More transmittance of light equals clearer, more comfortable vision.
