Abstract

Disclosed are loose glasses for persons with myopia and presbyopia to wear for a long time when looking at objects, and the glasses are single light concave lenses for presbyopia correction with a refractive power D_loose between the D_must and the D_after (including D_after). D_loose refers to the refractive power of the loose glasses, D_must refers to the necessarily fitted refractive power of the glasses, and D_after refers to the refractive power of the last glasses in the glasses sequence used for basically seeing objects clearly when human eyes adjust in the state of relaxation. Long-time wearing of the loose glasses for a person with presbyopia for seeing objects can produce the effect of obtaining an increased visual clarity of the closely watched objects in the eye, and long-time wearing of the loose glasses for a person for seeing objects can produce the effect of reducing eye fatigue.

Description

Loose glasses

The spectacles sequence refers to the diopter of the concave lens from large to small, the 0.00D of the flat lens to the diopter of the convex lens from small to large in order from front to back, that is, the glasses according to the refractive power..., -6.00D, ..., - 2.00D, ..., 0.00D, ..., +3.00D, ..., +7.00D, ... the order of the order. Glasses refractive power, myopic diopter, far vision diopter, adjustment amplitude, etc. can be added and subtracted according to the positive and negative properties, for example: (+4.00D) + (-2.00D) = +2.00D, (+3.00D)- (+2.00D)=+1.00D. When people look at an object for a long time, wearing loose glasses can reduce the effect of eye adjustment and visual fatigue. When the presbyopic person looks at the object for a long time, the single-lens concave lens in the wearing glasses can also produce an object that improves the close-up gaze obtained in the eye. The effect of visual clarity. Loose glasses are human eyeglasses for non-correcting myopia, hyperopia and presbyopia that reduce eye adjustment. Single-lens concave lenses are also presbyopic glasses for medium and high myopia and presbyopic correction of presbyopia. _Pine D D D _{will be} between _{the rear} _(after including D). Pine _finger-D glasses refractive power, the refractive power D will _shall refer to glasses, _the refractive power D refers to the basic look last object glasses used in the glasses when the human eye when the sequence regulating the relaxed state. The eye adjustment of the far-sighted person can be a far-sighted person in order to see the distant object. The loose glasses include a portion of the glasses, such as the upper or lower portion of the bifocal lens. The best loose glasses are loose glasses that produce the best results (about 100%). D + D _poor _good ≈D _thereof. D _good refers to the refractive power of the best loose glasses, D _poor refers to the eye when adjusting the relaxed state to see the infinity (usually 5 meters away) the refractive power of the last glasses used in the glasses sequence, the D _object is equal to the focal length The refractive power of the convex lens of the average distance between the wearing glasses and the object being viewed. Before the best loose glasses, the better the effect of the loose glasses in the lens sequence, the better the effect; after the best loose glasses, the looser the glasses in the lens sequence, the lower the visual clarity of the person's eyes in the eyes. The rest of the effect remains the same. When reading a book, watching a computer, writing, etc., you should choose to wear the eye to adjust the relaxed state. Basically, you can see the last loose glasses A in the eyeglass sequence at the farthest point on the object. You can move the head and Alternatively, the method of shortening the distance between the eye and the object at the far point of the object is selected from the last loose glasses behind the last loose glasses A in the sequence of glasses. One can choose two or more types of loose lenses with different refractive powers depending on the distance between different eyes and the object being viewed. In the long run, the higher the ratio of the time the person wears the loose glasses to the time of viewing the object when looking at the object, the better the effect. Long-term refers to more than the normal time of the current, for example: one face up to no presbyopia because of curiosity to wear other face-to-face and presbyopic glasses to read about a minute. The upper and lower parts of the multifocal glasses can be made into loose glasses lenses that look at two objects at different distances. The portion of the multifocal lens that has no lens, such as the upper portion, has a refractive power of 0.00D. Loose glasses of any size and any refractive power can be manufactured according to actual needs.

No elevation of D _will presbyopia = 0.00D; the front and presbyopia _was D = D + 0.50DD _will _tune ÷ 2, D refers to human Donder _adjusting amplitude adjustment value, if _necessary D <0.00D, to D _Must = 0.00D. Donder adjustment amplitude values: (30) 7.00, (35) 5.50, (40) 4.50, (45) 3.50, (50) 2.50, (55) 1.75, (60) 1.00, (65) 0.50, (70) 0.25, (75) 0.00, the number in parentheses is the age (full age), and the number after the brackets is the adjustment range (D). _A = D _after D + 0.2 × _(the A -A) × _(before D _after -D), amplitude adjusting means D _A A age, _{before the} D, D respectively refer to _the values before the adjustment amplitude A of age, after two adjusting the amplitude of the age of, a refers to the _age, a refers to the adjusted amplitude value a age age, for example: a = 47, then _the a = 50, _{the former} D = 3.50, _the D = 2.50; myopia must With glasses, the person who sees the distance (usually 2 meters away) needs to see the glasses worn by the object. If the distance between the eye and the object being viewed is equal, the nearsighted person can see the object with some kind of refractive power glasses and the naked eye, and the glasses are not loose glasses. If D _was _nearly + D + 0.50D> D _tune ÷ 2, myopia and presbyopia spectacles loose _bulk does not include D and 0.00D _near + D + D _was between 0.50D. Myopia and presbyopia the multifocal eyeglasses portion _thereof D = D + D _{will be} _near + 0.50DD _tone ÷ 2, D is the _near refraction myopia, the myopia D means _poor; A≤30 low degree of hyperopia and D of 30 < A ≤ 40 and D _far < 0.1 × (40-A) + 2.00 (excluding those with esotropia hyperopia) _{must be} = 0.00D. A farsighted person with 30 < A ≤ 40 and D _far ≥ 0.1 × (40-A) + 2.00 and a person with strabismus farsightedness _{must be} D _far . Hyperopia and presbyopia who _shall D = D + D _was + 0.50-D _tune _away ÷ 2, if D _was +0.50 <D _tune ÷ 2, it _{will be} D = D _far. D is _far hyperopic refraction, hyperopia's D refers to _{the poor.} _After D = D + KD _was _poor, K and related object is seen, it is seen more easily recognizable object, K increases. When a person looks at the font on a general book, K≈1.2. A person wearing the best loose glasses can see the object and wear the glasses in the sequence of glasses after the best loose glasses. The object is seen as a person who basically sees the object. The upper part of the refractive power of the multifocal lens of the loose glasses refers to the refractive power of the loose glasses without the presbyopia.

The oblique glasses mean that the focus of the convex lens is on the inner side of the twist line, that is, on the side of the nose, the focus of the concave lens is outside the twist line, or the focus of the convex lens or the light formed on the front side of the eye, that is, the light parallel to the line on the inner side of the eyeglasses passes through the lens. The midpoint of the zone, that is, the spot formed by the light that coincides with the squall line, is worn on the inside of the rifling to enable the eyeglasses to see the object substantially. Wearing glasses when looking at an object can reduce the fatigue of the eye collection and extraocular muscles. Slanted glasses are glasses for the collection of eye relief for human non-corrective strabismus. Design a large lens with the same refractive power (excluding the flat lens), take the spectacle lens in the edge area, the width direction of the spectacle lens is consistent with the diameter direction of the large lens, the outer side of the large convex lens is the outer side of the spectacle lens, and the outer side of the large concave lens is The inner side of the spectacle lens; firstly, the outer thickness of the large convex lens, that is, the outer thickness of the spectacle lens or the thickness of the outer side of the spectacle lens in the large concave lens, that is, the outer thickness of the spectacle lens, and then the shape of the two mirrors is determined according to the refractive power. Large lens outer diameter for making the best spectacles = d _coke × d ÷ d _distance + d _{outer -} d, d _cog refers to the distance between the center point of the two spectacle lenses in the large lens and the focus, d refers to the eye 瞳distance, d _from the outer side refers to two _outer ophthalmic lens is an ophthalmic lens to see objects and the center point of two connection distance, d refers to the distance glasses. The flat lens of the spectacles is generally a triangular prism. The inner side thickness of the spectacles is significantly larger than the outer thickness. The intersection point of the spectacles spectacle lens and the 瞳 line is the closer to the good point between the midpoint of the large lens and the intersection of the best spectacles lens and the 瞳 line in the large lens, or the convex lens at the d _distance . The focus or the midpoint of the light zone is closer to the front line between the positive line of the midpoint between the 瞳 line and the two eyes, and the spectacles reduce the degree of eye collection; the 瞳 point coincides with the good point, the focus of the convex lens or the light area The midpoint is on the front line, and the degree of relief is about 100%; the defect is outside the good point, the focus of the convex lens or the midpoint of the light zone is outside the positive front line, the degree of relief is about 100%, and the external object that is being watched is obtained in both eyes. The visual clarity is gradually reduced. The oblique glasses are made according to the D _mirror and the d _distance , and the D _mirror refers to the refractive power of the oblique glasses lens. When looking at an object, people should wear glasses with loose glasses and oblique glasses to minimize the adjustment and collection of the eyes. Optimal spectacles can reduce eye adjustment and collection by about 100%.

Users of loose glasses should regularly perform strabismus examinations. If the use of loose glasses triggers an oblique oblique and exotropia that may significantly impair the visual function of the eyes in the future, loose glasses users should use loose glasses in front of the ready-to-use loose glasses in the sequence of glasses, and the newly selected loose glasses can be used. In the next regular inspection, the loose glasses, the exotropia disappear, the weight is not increased or the degree of approval, the loose glasses user can also stop using loose glasses.
