Eye Care: Children & Computer Vision Syndrome
What Is Computer Vision Syndrome?
Computer Vision Syndrome (CVS) is a temporary condition which includes: eye strain, fatigue, neck and shoulder pain, headaches and blurred vision. Adults and children experience symptoms of CVS from focusing on the computer monitor for long periods of time without interruption.
Why Computers Are Hard On Our Eyes
Both children and adults are spending more and more time a day on the computer. Recent studies show the average person spends 1-3 hours per day in front of a computer. In general computer generated images are harder to maintain focus on then printed material which causes more stress on the eyes. Young children are more vulnerable to this because their visual system is not fully developed.
Can Excessive Computer Use Cause Myopia (Nearsightedness)?
Many optometrists, ophthalmologists, and eye doctors agree that children sitting in front of computers for hours are at higher risk for childhood myopia. Studies show that nearly 50% of adult computer users with a college education are nearsighted. Using computers for an extended period of time at a young age when the eyes are still developing may be a reason for this. Many pediatric optometrists , ophthalmologists, and eye doctors believe these stresses from computers, handheld video games, and cell phones are creating a myopia epidemic.
How to Prevent Computer Vision Syndrome
Here are some tips to help your children from suffering from CVS:
1. Every year a child should have a comprehensive eye exam by a optometrist, ophthalmologist or eye doctor.
2. Ergonomics are very important. Make sure the workstation ergonomics are configured appropriately for the child’s body size.
3. The child should view the computer monitor between 20 to 24 inches from his or her face, and the feet should touch the floor.
4. The position of the screen the child is looking at should be slightly down at an angle
5. Parents should monitor any potential problems the child maybe experiencing including: frequently rubbing the eyes or blinking, complaints of blurriness or eye fatigue and redness in the eyes.
6. Put daily limits on computer usage.
7. Minimize glare using an anti-glare filter and keep the monitor clean.
8. Take hourly breaks for 10 minutes so the eyes can rest.
Recommended Amount of Time for Kids on the Computer
These are suggested time limits to allow your children to spend in front of a computer per day:
| Age | Suggested Time Limit |
| Under 10 | 30 minutes per day |
| 10 – 13 | 1 hour a day |
| 14-15 | 2 hours a day |
| 16-18 | Parents best judgement |
If you feel your child is experiencing any of these symptoms please be sure to mention this while making an appointment for an eye exam.
