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.
Fluid is prevented from accumulating under the neurosensory retina, thereby preventing the retina from detaching. For laser retinopexy to be successful, the laser burns must be applied as soon as possible around the tear before retinal detachment develops. TYPES OF RETINAL DETACHMENT SURGERY It is not always possible to detect a retinal tear early enough before the retina detaches. When you are diagnosed with retinal detachment, you will be advised on one of the two main types of retinal detachment surgery procedures (which can be combined together if required): vitrectomy and scleral buckling surgery.
