This is because the extraordinary effort you are putting forth to focus is also causing your iris pupil to constrict, thereby reducing the total amount of light entering yo ur eye. Now push the near object back away to the point of clear vision and then bring it closer in to the point of blur and again, really concentrate to clear the blur. Repeat ten t imes. Now repeat step 1, tromboning for ten more time. You should do this exercises two or three times per day.
Results are often apparent within a few days and maximum benefit is achieved within about a month.
Before beginning each session, measure your near point at which the object begins to blur and at which it is definitely blurred, even with maximum effort. Use a measuring stick and measure from a poi nt at the bridge of your nose. As days pass, you should notice that the near point of blur becomes closer to your eyes. If you see no change within one week, you will not likely be successful. If you do see improvement, continue the exercise program until you no longer can record any additional benefit.
