A Simple Test For Myopia (Nearsightedness)
In simple terms, myopia is a visual defect in which a person
cannot see distant objects clearly. The near vision is usually
quite good. 1. To test for nearsightedness, you would need to
use a distant vision chart. Do not use your glasses or contact
lenses.
2. Place the chart on the wall at eye level under
well-illuminated condition.
3. Make markings of five feet from the chart, ten feet from the
chart, and twenty feet from the chart.
4. Start with the Twenty feet mark.
5. Cover your left eye with the left palm. Read the chart from
top to bottom. Note down the number of lines or letters that you
read correctly.
6. Move to ten feet mark, and repeat Step 5.
7. Again, move to five feet mark, and repeat step 5.
8. If you still cannot see the lines or letters from five feet
mark, move towards the chart until you can see clearly. Note
down the distance from the chart.
9. Cover your right eye with your right palm, and repeat Step 5
- 8.
Evaluation of Your Test - If you can see clearly from 20
feet, you have no or neglisgible myopia. - If you can see
clearly only at 20 feet mark, you have mild myopia. - If you can
see clearly only at 5 feet mark, you have moderate myopia. - You
have high myopia, if you vision is clear at less than five feet
mark.
