Computer vision syndrome (CVS) can lead to loss of peripheral vision and temporary blurred vision. CVS is the result of working in front of the computer too long and not looking away. Your computer screen stresses your eyes, and you suffer from both temporary and permanent vision problems. Luckily, there are many different things that you can do to prevent the most severe symptoms.
One of the most important things is to set up a workspace that allows you to have good posture, adequate lighting, and enough space to set up a copy stand so you do not have to look back and forth at your work as much. Combine this with yearly eye doctor exams and regular eyestrain exercises, and you will maintain your eyesight throughout your career.
