Sitting at a desk for eight hours a day, five days a week and staring at a screen, often in less-than-perfect lighting conditions, is something many people do without a second thought, but it is worthwhile taking extra precautions to protect the eyes when computer use is an integral part of work activities.
Problems Caused by Computer Use
Spending too much time in front of the computer can cause computer vision syndrome (CVS). The symptoms of CVS include twitching eyes, blurred vision, headaches or migraines and difficulty focusing on objects in the distance. These occur because the eyes have difficulty changing focus from keyboard to screen so often and become fatigued.
Aside from the physical discomfort and short-term problems, computer vision syndrome can cause long-term sight difficulties and become a serious health issue if not dealt with.
The physical office conditions should be improved as much as possible with things such as better lighting and an assessment of the desk and chair position, as well as regular breaks away from the screen, at least one break every 20 minutes. Anti-glare computer glasses are also beneficial and can eliminate problems caused by prolonged computer use.
How Anti-Glare Computer Glasses Work
Anti-glare computer glasses are specifically designed to reduce eye strain while working at a screen, helping to improve focus and get rid of associated problems.
Computer screens are particularly problematic because of the high refresh rate – the eyes have to deal with the tiny and regular changes to the light received, causing strain. The anti reflective coating of computer glasses eliminates the reflection of light from both the front and back of the lenses, which means the eyes do not have to work so hard and focusing becomes easier.
The anti-glare coating on computer glasses will also reduce problems caused by harsh office lighting and boost contrast, which is often lacking on computer screens and is another factor that causes eye strain as they struggle to focus accurately.
By reducing eye strain computer glasses can, in turn, help to improve posture, which will further aid people who have difficulty focusing while at their desk.
Contact lens wearers may get an added benefit from wearing anti-glare computer glasses. Screens generate heat and can make the air around them seem drier, which is often a cause of discomfort for those who wear contact lenses. Computer glasses can act as a barrier and make viewing the screen more comfortable.
Other things to know about computer use and eyesight
As well as wearing anti-glare computer glasses and improving the overall environment, computer users can do eye exercises to help improve their vision and reduce eye strain. Even simple steps such as spending a few minutes looking at something other than the screen and blinking more often can reduce discomfort. Changing what is being looked at every 20 minutes or so is vital to keep the eyes focusing correctly and avoid â€œlock-upâ€, where the eyes get stuck in one focal depth. It can also help to close the eyes for a few minutes and gently massage them.
Employers are required by law to take steps to reduce health problems in the workplace. They must pay for an eye test every year if the job involves continued computer use and take steps to ensure the desk and office environment are suitable to screen work.
