Floaters are deposits of various size, shape, consistency, refractive index, and motility within the eye’s vitreous humour, which is normally transparent. At a young age the vitreous is perfectly transparent but, during life, imperfections gradually develop. The common type of floater, which is present in most people’s eyes, is due to degenerative changes of the vitreous humour. The perception of floaters is known as myodesopsia. Floaters are visible because of the shadows they cast on the retina or their refraction of the light that passes through them, and can appear alone or together with several others in one’s field of vision. They may appear as spots, threads, or fragments of cobwebs, which float slowly before the observer’s eyes. Since these objects exist within the eye itself, they are not optical illusions but are entoptic phenomena.
MY LIFELONG QUESTION HAS BEEN ANSWERED!
We were discussing homosexuality because of an allusion to it in the book we were reading, and several boys made comments such as, “That’s disgusting.” We got into the debate and eventually a boy admitted that he was terrified/disgusted when he was once sharing a taxi and the other male passenger made a pass at him.The lightbulb went off. “Oh,” I said. “I get it. See, you are afraid, because for the first time in your life you have found yourself a victim of unwanted sexual advances by someone who has the physical ability to use force against you.” The boy nodded and shuddered visibly.“But,” I continued. “As a woman, you learn to live with that from the time you are fourteen, and it never stops. We live with that fear every day of our lives. Every man walking through the parking garage the same time you are is either just a harmless stranger or a potential rapist. Every time.” The girls in the room nodded, agreeing. The boys seemed genuinely shocked. “So think about that the next time you hit on a girl. Maybe, like you in the taxi, she doesn’t actually want you to.
I feel pretty much the same way about the periodic table, I’ve just never been able to express it so well.
