People are getting on in years, a lot of physiological functions will all change. Such as to eyes, with the years, eyes crystalline to realize and harden gradually, its elasticity is reduced gradually, in addition, the ciliary muscle in charge of the regulating action becomes weak, so the intersection of regulation and function fail, lead to the fact, think nearly things become difficult, this is presbyopia that we are commonly called as. If appear old flower already, strong to prop up, wear presbyopic glass, ciliary muscle drained to regulate then, sure to aggravate, read difficult, produce the intersection of giddy and the intersection of eyes and a lot of symptoms such as being bloated, influence life and work, this is very unwise. So, the always colored glasses do not need the delay as matching to match promptly.

What's more the distance of pupil between two of us is not the same, the pupil distance is small comparing with the time of seeing far while reading, it is determined accurately that this appears through having an eye test. Secondly, should understand looking at things to need of each one. If small some in degree of the always colored lens, far - some distances seen clearly, the range seen clearly is a little greater. On the contrary, if large some degrees of the presbyopia lens, the distance seen clearly is a little nearer, the range seen clearly is a little smaller. Wear behind the presbyopic glass, move to before being near and a bit permitted - -Like read from 30 centimetre about. But if your working bench is lower, or maintain the work with machine, it should be more than 30 centimetres a bit to be so near; On the contrary, if your distance of job is nearer, it is a bit just within 30 centimetres nearer. So, should explain clear your need to the optometrist while mixing the presbyopic glass and do appropriate adjustment to the lens degree. Some middle-aged and elderly people be thought it is near without being looked from afar that help of glasses needed,then buy soon two glasses -. If dislike two pairs of too troublesome glasses.
