The presbyopic glass is worthy of not hesitating as mixing
If middle-aged and elderly people appear presbyopia is strong to prop up, wear presbyopic glass, ciliary muscle too tired and sure to aggravate difficulty while reading then, produce a lot of symptoms such as being bloated of giddy eyes, influence life and work, this is very unwise. So, the presbyopic glass does not need the delay as matching to match promptly. The always colored lens should be worn separately according to each one's different eyesight situations, avoid buying a pair of presbyopic glass to wear at will most. Because the detailed conditions not in accordance with one's own eyes probably of aging mirror bought at will, wear it by not only depended on the thing can't be lasting and clear, but also it is tired to increase eyesighting, will even inspire some diseases. Then, what should be paid attention to while mixing presbyopic glass? Should go to have an eye test first. Should understand crooking all state of one's own eyes, it is inconsistent that some people always spend the intensity with two eyes, either have long sight, myopia, astigmatism originally, have an eye test, buy, come on, wear by one presbyopic glass so, solve problem, can cause, reply, look at and eyes bloated, make eyesight drop. Even two unanimous eyesight, want, have an eye test accurately, regulate force, confirm the degree rationally according to the intersection of eyes and one's own surplus too, in order to be more relaxed while using the eyes at short range. 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 watching the distant place while reading, this can only be determined accurately 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, the distance seen clearly is a little farther, 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 general reading the distance before being near and a bit permitted, namely the eyes are about 30 centimetres from the object. But if your desk 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 see and look from afar the near help that need the glasses, then will buy two pairs of glasses soon. If dislike two pairs of too troublesome glasses. Can select burnt the intersection of gradation zone and lens more whose diopter is can cumulative for use. Noon paper of work
