Myopia is defined as nearsightedness. This means you can focus more easily on near objects such as when reading than on distant objects. How well one see close-up varies depending on the level of nearsightedness a person has. Myopia is typically due to the shape of the eyeball being more oval than round, causing the light entering the eyes to focus in front of the retina rather than directly on the retina.

The causes of myopia can vary from person to person, but below are some of the variables that may affect one's near vision:
- Amount of time on detail work such as on computers, accounting, sewing, etc.
- Personality type. Emotional factors can be contributors.
- Diet and nutrition
- Free radicals. Researchers suspect that oxidative stress may be a contributing factor in myopia.1
Here are some tips:
- Supplement with nutrients that support healthy vision.
- Diet and lifestyle protocol - see our recommendations for diet / lifestyle.
- Natural daylight. Some research suggests that natural light exposure may counter-balance too much indoor/close up work causing strain on the eyes. Even on an overcast day, exposure to natural light for 2-3 hours may be helpful.
- Manage chronic stress. Long-term tension has been shown in research to contribute to serious disease and is suspected as a causative factor in eye conditions.
- Eat healthy. Research has verified that a healthy diet that includes daily intake leafy, green vegetables and whole grains can significantly lower the likelihood of developing eye disease.
- Exercise. Develop a regular exercise routine. A minimum of 20-30 minutes of vigorous walking or swimming a week for example is excellent for eye and overall health.
- Computer Users. If you are a computer user, please review our section on computer fatigue syndrome.
- Learn how nearsightedness can be improved through vision therapy.
- See all vision therapy products.
- Finally, read a fascinating report about reducing myopia.
- Glaucoma: Heavy computer user? Research suggests that heavy computer users who are also nearsighted or farsighted are more at risk.
- Computer eye strain
- Asthenopia (eye fatigue)
