Abstract

A glasses sequence refers to arrangement of glasses according to the sequence of ..., -6.00D, ..., -2.00D, ..., 0.00D, ..., +3.00D, ..., +7.00D, ... When people wear a pair of loose glasses for a long time when looking at an object, eye adjustment and visual fatigue can be reduced; when people with presbyopia wear a pair of loose glasses for a long time when looking at an object, a monochromatic-light concave lens in the glasses can improve apparent resolution of the objected looked at a close distance in the eyes. D<optimal> approximates to D<infinite> and D<object>, wherein D<optimal> refers to refractive power of optimal loose glasses, D<infinite> refers to refractive power of the eventual lens in the glasses sequence used when people can clearly see a place at an infinite distance (normally beyond 5 meters) in a relaxed state, and D<object> refers to refractive power of a convex lens with a focal length equal to an average distance between wearing spectacle lenses and the object which is looked at. The loose glasses are glasses used for mitigating eye adjustment instead of correcting myopia, long sight and presbyopia, are monochromatic-light concave lenses and are presbyopia glasses for people with medium-degree and high-degree myopia and presbyopia for correction of presbyopia.

Description

Pine glasses

Glasses sequence refer to glasses by concavees lens refractive diopter from big to small, the 0.00D of plano lens to the refractive diopter of convex lens from small to large according to the arrangement of order from front to back, namely glasses are according to refractive power ... ,-6.00D ... ,-2.00D ..., 0.00D ... ,+3.00D ... ,+7.00D ... the arrangement of order.Glasses refractive power, the myopic refractive number of degrees, the hyperopic refractive number of degrees, the amplitude of accommodation etc. can add mutually according to having positive and negative several character, subtract, such as: (+4.00D)+(-2.00D)=+ 2.00D, (+3.00D)-(+2.00D)=+ 1.00D.People wears loose glasses and can produce and alleviate eyes and regulate and asthenopic effect when seeing object duration, presbyope's monochromatic light concavees lens worn when seeing object duration in loose glasses can also produce the effect of the vision definition that object that raising closely watches attentively obtains in eyes.Pine glasses are non-myopia corrections of people, long sight and presbyopia alleviate the glasses that eyes regulate, monochromatic light concavees lens or middle and high degree myopia and presbyope correct the presbyopia glasses of presbyopia.D _pineat D _mustwith D _after(containing D _after) between.D _pinerefer to the refractive power of loose glasses, D _mustthe refractive power that finger must get the right lensses for one's eyeglasses, D _afterrefer to that people sees the refractive power of last glasses in glasses sequence used for object substantially clearly when eye adjustment relaxation state.It can be that hyperope is in order to see distant objects clearly that the eyes of hyperope regulate.Pine glasses comprise certain part of glasses, the upper part of such as bifocals eyeglass or lower part.Best loose glasses refer to the loose glasses producing optimum efficiency (about absolutely).D _good≈ D _thoroughly+ D _thing.D _goodrefer to the refractive power of best loose glasses, D _thoroughlyrefer to that people sees infinite point (being generally beyond the 5 meters) refractive power of last glasses in glasses sequence used for object clearly, D when eye adjustment relaxation state _thingrefer to that focal length equals people institute hyperphoria with fixed eyeballs eyeglass and seen the refractive power of the convex lens of mean distance between object.Before the loose glasses of the best, loose glasses in glasses sequence more after, the effect of generation is better; After the loose glasses of the best, loose glasses in glasses sequence more after, the vision definition that the object that people watches attentively obtains in eyes is lower, and all the other effects are constant.People reading a book, see computer, will select when to write etc. to wear and work as eye and regulate during relaxation state and substantially see the last loose glasses A in glasses sequence object needing the solstics place seen clearly clearly, can by moving-head and (or) position of object thus the method selection shortening the spacing at far point place on eyes and the object last loose glasses in glasses sequence in the end after loose glasses A.People can select two kinds or more loose glasses of planting different refractive power according to different eyes with by the distance seen between object.In the long run, the time that people wears loose glasses when seeing object accounts for sees that the effect of the higher generation of the ratio of object time is better.Refer to time long exceed this type of normal time existing, such as: face without presbyope for one and face and about one minutes of the presbyopia glasses of presbyope reading because curiosity wears other.Upper and lower two parts eyeglass of multifocal spectacles can be manufactured the loose eyeglass seeing two different distance near objects.The refractive power of the part of eyeglass such as upper part of not having of multifocal spectacles is 0.00D.The loose glasses of arbitrary dimension and any refractive power can be manufactured according to actual needs.
