The new pair of glasses may not necessarily be wrong, it is just that your eyes need to adjust to the new power. There is usually a breaking in period for new glasses whenever the prescription changes ( just like shoes). The breaking in period is faster if the glsses are worn continueously. If you wear it occasionally, your eyes will need more time to adjust. I would advise you not to throw away the new glasses just yet.
To understand why sleep is important, think of your body like a factory that performs a number of vital functions. As you drift off to sleep, your body begins its night-shift work: 1  Healing damaged cells. 2  Boosting your immune system.  Recovering from the dayâs activities.

Studies show that a good night's sleep improves learning.Whether you're learning math, how to play the piano, how to perfect your golf swing, or how to drive a car, sleep helps enhance your learning and problem-solving skills.hen you don't get enough sleep, your level of ghrelin goes up and your level of leptin goes down. This makes you feel hungrier than when you're well-rested. Sleep also affects how your body reacts to insulin, the hormone that controls your blood glucose (sugar) level.
