Glasses

I was practically out of ideas for this (second to last?) blog when I realized that my blog topic was right in front of my eyes (literally). Ok, so it's a pretty boring topic, but it goes back to some concept we learned in the optics section. I'm nearsighted, so I wear my glasses (or contacts) to help me see things that are far away. My glasses have diverging lenses, which make objects appear smaller but clearer. The diverging lenses refract light so that the images appear at the retina instead of in front of the retina. People who are farsighted have glasses with converging lenses to make closer objects appear clearer. The converging lenses refract light rays in order to adjust the position of the image so that it appears at the retina instead of behind the retina. Well, I'm definitely going to be using my glasses until late at night everyday this week seeing as there are tests pretty much every day this week...good luck to everyone who's in ap phys, apush, pch, dance showcase, and other exam giving classes this week...
