Let's take a look at the four ways we can transform a tangent function and graph. A changes the amplitude, or how steep the graph is along the y axis. B changes the period, or how wide one pattern of the graph is. C changes the phase shift, or how the graph is shifted to the left or the right. D controls the vertical shift, or how the graph is shifted up or down.
Wear your corrective lenses to see where you are going or it won't be just eyes hurt. Floaters, the little bits of scar tissue in the jelly of the eye that lead or lag behind the motion of the eye thus drift or float are made worse in excessive eye rubbing or worse can lead to retinal tears or detachment. Avoid this practice. Treat the itching if that is what the problem is in the first place.
As mentioned above, do not rub your eyes after LASIK eye surgery. During your LASIK recovery time, the corneal flap is healing and although very rare, the flap can become displaced caused by rubbing the eyes. You can minimize the risk of a flap complication by not rubbing your eyes.uring your LASIK recovery time it is normal to experience side effects as your eyes heal. These side effects are generally short term during the 3-6 month healing period and will typically not affect your daily routine.
