New glasses, i.e., spectacles, eyewear, specs, can be an opportunity to expand or contract one's horizons. Anyone who has ever worn progressive lenses, bifocals or trifocals, will tell you there is a period of readjustment during which the eyes are retrained and adjust to the "new view". For some, the adjustment period can last a day or two or extend to two or more weeks. Some abandon the process because the "new view" puts more strain on the wearer than the wearer can bear. Perhaps something went wrong with the assessment process during which the patient's eyes were examined and an inaccurate prescription was determined? Perhaps one has become so accustomed to bad habits that one cannot see that the habits are bad and in need of release?
One tends to develop many bad habits over seven years: bad posture; repetitive stress injuries caused by constantly shifting one's head to accommodate restrictive aspects of poorly constructed lenses. Anyone who has been subject to a faulty prescription knows the plague of headaches or neck problems which can develop even in a relatively short period of time.
