Abstract
The utility model relates to a kind of prevention and slows down myopia development eyeglass, and it is characterized in that eyeglass is designed to see far field from top to bottom successively, takes a fancy to apart from district and see near region, wherein said taking a fancy to accounts for eyeglass 3mm-15mm transverse area apart from district.The utility model fully takes into account teenager and is accustomed to and eyeball physiological function with eye, organically eyeglass is divided three different luminosity regions, and can the custom of utilization eye, look up the natural action far leaned over a book, what become to have darker luminosity in eyeglass upper design sees that far field, middle part down shoal gradually, and eyeglass bottom is the near region of seeing of either shallow luminosity, ensures A nearsighted person's eye hygiene, coordinate people's ocular accommodation, finally reach the object that retarding myopia is deepened or worsened.
Description
Technical field:
The utility model belongs to concave lens field, and particularly one prevention slows down myopia development eyeglass.
Background technology:
Existing progressive focus-variable lens is all for presbyopic glasses, and solution need carry the trouble of many pair of glasses.Because presbyopic is eyeball degenerative problem, often along with the age increases, and the regulative mechanism of eyeball is progressively deteriorated, and the presbyopic number of degrees are generally within 300 degree.But namely teen-age myopia be cause with eye is improper, especially depending on the result that nearly thing fatigue causes, make to see far unintelligible, need wear glasses to correct.And at present myopia join mirror optometry be by see far clear for the purpose of, also namely ensureing that attending class looks at the blackboard can know for wanting, and between using in a large number at the moment, namely be in-plantly do one's assignment and read a book, if still use the glasses of attending class, after some time, as reduced vision caused again after halves, again wear darker glasses again.How to utilize the principle of gradual change presbyopic glasses, design a kind of have see far away, see eyeglass that is near and that take a fancy to apart from subregion, namely become the object of the utility model research.
Summary of the invention:
The purpose of this utility model is that design is seen far field, taken a fancy to apart from district and see that the prevention of near region slows down myopia development eyeglass a kind of being divided into from top to bottom.
Technical solutions of the utility model are achieved in that a kind of prevention slows down myopia development eyeglass, and it is characterized in that eyeglass is designed to see far field from top to bottom successively, takes a fancy to apart from district and see near region, wherein said taking a fancy to accounts for eyeglass 3mm-15mm transverse area apart from district.Be accustomed to eye by people, see that far field is located at top, when often seeing far away, eyeball is the up luminosity naturally utilizing top darker, as watched the writing on the blackboard of blackboard; Taking a fancy to and be generally look squarely apart from district, as seen TV etc., moderate luminosity district can be utilized to watch; Read a book and do the homework, the naturally descending action of eyeball, just utilizing the more shallow luminosity seeing near region, observe nearly thing, avoid watching nearly thing for a long time with darker luminosity, cause the problem of myopia development.
Described take a fancy to apart from district be grading structure, luminosity becomes gradient to successively decrease from top to bottom, decrement 51 to 100 degree between, the spacing of each decreasing gradient is less than 5mm.Because teenager's eyeball regulative mechanism is good, and myopia degree is often higher again, and generally all more than 500 degree, large gradient is successively decreased change, has both considered that eyeball adapted to, and can take into account again depth change demand.
Describedly see far field, take a fancy to apart from district and the light varience seeing near region, be located on the male bend face of casting mirror.Keep the recessed bent face of casting mirror complete, to process astigmatism.
The utility model fully takes into account teenager and is accustomed to and eyeball physiological function with eye, organically eyeglass is divided three different luminosity regions, and can the custom of utilization eye, look up the natural action far leaning over a book and coordinate and lift eye, what become to have darker luminosity in eyeglass upper design sees that far field, middle part down shoal gradually, and eyeglass bottom is the near region of seeing of either shallow luminosity, ensure A nearsighted person's eye hygiene, coordinate people's ocular accommodation, finally reach the object that prevention slows down myopia development or deterioration.

Embodiment:
With reference to Fig. 1, prevention slows down myopia development eyeglass, and when eyeglass is shaping, outline is circular, and cut into the moulding coincide with picture frame during assembling, final outline is class rectangular configuration, ensures the larger visual field; Eyeglass is designed to see far field 1 from top to bottom successively, takes a fancy to apart from district 2 and see near region 3, wherein takes a fancy to and accounts for eyeglass 3mm-15mm transverse area apart from district 2, take a fancy to and determine with the depth of myopia apart from the width shared by district 2; And to take a fancy to apart from district 2 be grading structure, luminosity becomes gradient to successively decrease from top to bottom, and decrement is between 51 to 100 degree, and the spacing of each decreasing gradient is less than 5mm; See far field 1, take a fancy to apart from district 2 and the light varience seeing near region 3, be located on the male bend face of casting mirror, the front lens surface also namely described in tradition, keep the curvature of the recessed bent face of eyeglass, to process astigmatism luminosity.
With reference to Fig. 2, during casting mirror, front lens surface is planar structure, and it is seen far field 1, takes a fancy to apart from district 2 and the light varience seeing near region 3, is located on the front of casting mirror.With reference to Fig. 3, during casting mirror, front lens surface is male bend structure, and it is seen far field 1, takes a fancy to apart from district 2 and the light varience seeing near region 3, is located on the male bend face of casting mirror.The eyeglass male bend face mentioned in the utility model also refers to and hereby illustrates the front of eyeglass.
Reference Fig. 4 to Fig. 6, Fig. 4 are 400 degree of low degree short sightedness eyeglasses casting mirror examples, and see that far field is 400 degree, see 150 degree, near region, taking a fancy to distance district each luminosity gradient decrement is 60 degree; Fig. 5 is 850 degree of moderate and high myopia eyeglasses, sees 850 degree, far field, sees 450 degree, near region, and taking a fancy to each luminosity decrement in distance district is 75 degree; Fig. 6 is 900 degree of high myopia eyeglasses, sees 900 degree, far field, sees 600 degree, near region, and taking a fancy to each luminosity decrement in distance district is 100 degree.
Eye test new opinion, teenager, student's optometry not only will be examined far, and reinforcement optometry sees near luminosity, in order to making upper and lower luminosity difference between 101 degree to 400 degree, eyesight can not make eyeball for a long time seeing luminosity far away at present, and automatic function is adjusted to sees near vision.
