Abstract
The utility model discloses soft corneal light-proof contact lens, belonging to the filed of medical instrument. The soft corneal light-proof contact lens comprise lens bodies, wherein the center parts of the lens bodies which are made from soft hydrophilic and light-proof materials protrudes to form arc parts which are closely adhered to corneas. The soft corneal light-proof contact lens adopt monomer lens to replace the way that light-proof cloths are positioned on eyes, and particularly the center parts of the lens bodies protrudes to form the arc parts which are closely adhered to the corneas, so that the light-proof lens are closely adhered to walls of eyeballs to absolutely obstruct light source, and patients can not observe external things due to the movement of the eyeballs to improve the treatment effect to weak sight. Furthermore, the soft corneal light-proof contact lens have simple wearing, are directly adhered to the walls of the eyeballs so that the lens with deep color cover pupils accurately, have beautiful use, are easily accepted by a sick child, relatively shorten treatment time, increase the contact area between the lens bodies and tears when wearing, and reduce foreign body sensation when wearing.
Description
Technical field
The utility model relates to medical instruments field, relates in particular to the light tight place's mirror that connects of a kind of soft cornea.
Background technology
At present, generally the wear glasses mode of gobo of the treatment of amblyopia is carried out, because considerable time of treatment of amblyopia, especially children's treatment is generally needed the time in 2 to 3 years, in therapeutic process, need infant to cooperate, when still gobo is treated because infant is worn glasses with the positive of the head of a family, can not be with the cornea complete closed, the side of the easy transmitted through glasses gobo of children is observed the external world, has reduced result of treatment, is unfavorable for the treatment of amblyopia.And the gobo that infant is worn is generally dark cloth such as black, make glasses look inharmonious not attractive in appearance, usually be subjected to partner's ridicule after infant is worn, allow infant produce antagonistic psychology and mismatch treatment, prolong the course of treatment that amblyopia is cured, caused missing best treatment opportunity easily.This shows that prior art needs further improvement.
The utility model content
The light tight contact lense of a kind of soft cornea that the utility model provides carries out scientific and reasonable improvement to the eyes of being furnished with gobo in the prior art, and is to improve the result of treatment to amblyopia, more attractive in appearance when the patient is worn.
For solving the problems of the technologies described above, the utility model scheme comprises:
The light tight contact lense of a kind of soft cornea, it comprises the eyeglass body, wherein, and eyeglass body central part that light-proof material make hydrophilic by flexibility forms a curved portions that is used to be close on the cornea to outer lug.
The light tight contact lense of described soft cornea, wherein, above-mentioned eyeglass body outer side edges is circular.
The light tight contact lense of described soft cornea, wherein, the diameter of above-mentioned curved portions is greater than the diameter of wearer's cornea.
The light tight contact lense of described soft cornea, wherein, the distance around above-mentioned eyeglass body side and the eyeball between the muscle is 16 millimeters.
The light tight contact lense of a kind of soft cornea that the utility model provides, adopt the monomer eyeglass to replace on eyes, being provided with the mode of gobo, especially eyeglass body central part is to outer lug, form a curved portions that is used to be close on the cornea, lighttight eyeglass is close on the wall of eyeball, cut off light source fully, make the patient can not observe outside things because of the motion of eyeball, improved result of treatment to amblyopia, and the utility model eyeglass is worn simply, directly pastes on the wall of eyeball and its deep-color lens is very good covers on the pupil, wears attractive in appearance, make the easier acceptance of infant, shortened treatment time relatively.
Description of drawings
Fig. 1 is the side-looking cross-sectional view of eyeglass body in the utility model;
Fig. 2 be in the utility model the eyeglass body along the plan structure synoptic diagram of curved portions.
Embodiment
Below with reference to accompanying drawing, comparatively detailed explanation is carried out in each preferred embodiment in the utility model.
The utility model provides a kind of soft cornea light tight contact lense, lighttight eyeglass body central part outwards convexes to form a curved portions that is used to be close on the cornea, cut off external light source fully, thereby improved result of treatment amblyopia, more attractive in appearance when the patient is worn.As Fig. 1 and shown in Figure 2, the light tight contact lense of soft cornea comprises eyeglass body 1, and eyeglass body 1 central part that light-proof material make hydrophilic by flexibility forms a curved portions 2 that is used to be close on the cornea to outer lug.Because the eyeglass body is made by lighttight material, the curved portions that is close on the cornea also is lighttight, cut off external light source fully, make the not sensitization of eyeball of patient's amblyopia, improved result of treatment to amblyopia, and eyeglass of the present utility model is placed on intraocular, can not influence the form of patient outside, has improved aesthetic measure.In order further to improve performance of the present utility model, as shown in Figure 2, eyeglass body 1 outer side edges is circular, and the diameter of curved portions 2 is greater than the diameter of wearer's cornea, distance around eyeglass body 1 side and the eyeball between the muscle is 16 millimeters, when eyelid blinks, still can make and relatively move between eyeglass body and the eyeball and be not subjected to the influence of muscle around the eyeball, increased the contact area of eyeglass body and tear when wearing, reduce the foreign body sensation when wearing glasses body, improved level of comfort and security when wearing glasses body.
In sum, the utility model provides a kind of soft cornea light tight contact lense, adopt the monomer eyeglass to replace on eyes, being provided with the mode of gobo, and eyeglass body central part is to outer lug, form a curved portions that is used to be close on the cornea, increased the contact area of eyeglass body and tear when wearing, reduced the foreign body sensation when wearing glasses body, and the utility model has cut off light source fully, make the patient can not observe outside things, improved result of treatment amblyopia because of the motion of eyeball.
Should be understood that; above-mentioned description at preferred embodiment is comparatively detailed; can not therefore think restriction to the utility model scope of patent protection; those of ordinary skill in the art is under enlightenment of the present utility model; do not breaking away under the scope situation that the utility model claim protected; can also make various deformation such as replacement, simple combination, these all fall within the protection domain of the present utility model, and the scope of asking for protection of the present utility model should be as the criterion with claims.
