I learned a trick in 6th grade to see the board without glasses – pull the corner of your eye back, squash the eyeball a bit and voila, you can see clearer. This trick got me through the next three years. Vanity ruled my young life. Finally, I gave in and got glasses in sophomore year. Learned later in intro to psychology that the nearsighted eye is too long. The psych book never explained that you could fix the problem manually.
