Snellen Eye Chart

The Snellen Eye Chart is a tool used by eye care professionals to measure visual acuity, or how well a person can see at various distances.

Indeed, using a Snellen Eye Chart at home can provide a rough assessment of distance vision clarity. It is particularly useful for screening purposes, especially in children who may not be aware of vision issues or unable to express them clearly.

DIRECTIONS FOR USE

For the best accuracy (and to prevent memorization), have someone assist you when testing your vision with this eyechart.

If you use eyeglasses or contact lenses for driving or other distance vision tasks, wear them during the test.

1. Choose a Suitable Location, Hang or place the chart on a well-lit wall at eye level. Ensure there is enough distance (typically 20 feet or 6 meters) between the chart and the person being tested.

2. Cover one eye with your hand, a large spoon or some other item that completely blocks the vision of the coveredeye.

3. Identify a line on the chart you can comfortably read. Read the letters on that line aloud. Have your assistant stand near the chart and record your accuracy.

4. Continue trying to read the letters on each successively smaller line. Do not squint.

5. Have your assistant stop you when you fail to correctly identify at least 50 percent of the letters on a line.

6. Switch to the other eye and repeat.

ATTENTION :It is important to keep in mind that while the Snellen Eye Chart is a useful tool for screening, it does not replace a comprehensive eye examination by an eye care professional. If there are concerns about vision or if the results are abnormal, it is essential to consult with an optometrist or ophthalmologist for a thorough evaluation and appropriate management.
