                                   Why does presbyopia occur?

                                   Evolutionary biologists think  that humans were designed to  last
                                around 40 to 45 years. This explains why we lose our vision for near
                                distance  and  undergo  various  physiological  changes  such  as
                                menopause  in  women.  Today,  human  innovation,  and  man’s  keen
                                intellect, have allowed us to surpass this barrier. Pin in eye procedure
                                is  another  modern  medicine  technique  designed  to  outlive  our
                                expiration date.
                                   In early human civilizations, most people survived as hunters or
                                farmers. People  with poor vision did not  fare well against the wild
                                animals.  Therefore,  hunters  with  poor  vision  were  not  able  to
                                survive. While farmers on the other hand, did not need great vision,
                                and could continue working until they were almost blind.
                                   Following  the  industrial  revolution,  modern  city  based  society
                                evolved,  and  the  need  for  vision  became  greater.  Thus  there  was
                                renewed  interest  in  the  treatment  of  vision  disorders.  Various
                                methods  evolved,  merged,  diversified,  and  this  gave  way  to  new
                                techniques. This interesting and challenging period of discoveries and
                                inventions is still  the  foundation  of  modern  Cataract,  Lasik,  Prelex
                                and Pi in eye surgeries.

                                   Can  muscle  exercise  strengthen  the  muscles  and  preserve
                                reading?

                                   Over   the   years   many   scientists   have   explored   the   idea   of
                                strengthening eye muscles with various exercises. They have ranged
                                from the use of candles to computers. Eye surgeons and inventors
                                even  devised  surgeries  to  lengthen  and  strengthen  the  muscles
                                involved  in  changing  the  shape  of  the  lens.  As  you  might  have
                                guessed none survived the test of people and time. There is no harm
                                in trying some muscle exercises, however over-straining can lead to
                                headaches and eye pain.
