How to test your vision online?

Previously I have written on my blog about the importance of good eyesight for speed reading. In addition, I have provided you some tips about how to keep a good near vision
Today I will tell you how you can easily test your eyesight online, without going to the doctor. Of course it is recommended that you check your vision regularly at a specialist, but this is for a quick test for being sure that everything is ok.
When talking about testing eyesight we have to distinguish between two types of eyesight. Near vision is an ability to see objects clearly at 30-50cm. As this is our usual reading distance then it is the near vision that affects our reading speed.
Distant vision is an ability to see far objects, which can be meters of even kilometers away from our eye. Although we do not read texts usually at these distances, reading can affect our distant vision. Therefore it is recommended to also check your distant vision regularly.
For testing your near vision you can use a following test. For doing that test you will need to print a following chart
Perform this test in a well lit room. Do not take this test if you are tired. Wear the glasses or contact lenses you normally use for reading. Keep both eyes open. Hold the Near Vision Chart about 14 inches (35 cm) away from your eyes. If your near vision is OK then you should be able to read the sentences printed on the chart as well as the row of the “C’s” (you should be able to tell where each opening is in the row of “C’s”)
For testing your distant vision you can print a test chart here
Perform this test in a well lit room. Tape the first page of the chart to a bare wall with no windows. The chart should be at your eye level. Stand 10 feet (3m) away from the chart. If you already have glasses for distance vision, wear them during the test. You should perform this test separately with each eye, so cover one eye for taking the test. Read each of the letters from left to right starting with the largest line. Continue moving through the chart to the smallest letter you are able to read. You may write down the letters as you see them. You pass a line when you can correctly read at least 3 out of 5 letters. Write down the lowest line on the chart that you passed.
Adults should be able to read the 20/40 line with each eye. You passed the test if you passed the 20/40, 20/32 or 20/20 line in each eye.
So you can use these test for making a quick check-up for your eyesight. If you find that it is not up to the required standards then you should visit your doctor.
