An individual can receive a very good vision screening using computer generated eye charts. Testing your vision online can give you a good estimation of your vision acuity and can help identify early signs of certain types of eye diseases.
Most organizations recommend or suggest downloading and printing each chart and using the printed chart for the best results but a fair test of your vision is possible using the eye charts on the computer monitor.

Testing stressed or tired eyes would not produce an accurate screening of your vision. Eye doctors suggest testing the vision in the morning while eyes are fresh. A testing area, which is uncomfortable to the person or the eyes, will affect the test results. Changing the test directions or not following the directions of each exam exactly may produce faulty test results.
