Headaches, eyestrain, neck pain, back pain, fatigue and general discomfort are just some of the symptoms of Computer Vision Syndrome.
If you are using a digital device for several hours a day and not wearing the appropriate lenses you can suffer from the above symptoms. Wearing the wrong lenses like a general progressive lens creates poor ergonomics and increases the chances of discomfort.
Computer users should use a lens that offers the correct Rx for the focal distances needed. The Rx is different when focusing on a computer at 30 inches verse focusing at a typical reading distance of 15 inches. Computer lenses enhance the intermediate and reading optics offering increased visual comfort, better ergonomics and a more productive and happier existence in front of the computer.
Computer lenses can also have a blue light blocking filter added to increase visual comfort and protect the eye from harmful blue light.
