Abstract
The invention provides a soft lens and hard lens combined contact lens, which comprises a central part of an optical region, a peripheral part surrounding the central part, and a jointing part, wherein the central part is a hard contact lens body; the peripheral part is a soft contact lens body; and the jointing part comprises a bump of the central part and a recess of the peripheral part. A manufacturing method of the soft lens and hard lens combined contact lens comprises the following steps of: injecting a hard lens material into a first female die, inserting a male die and polymerizing to form a first buckling material; injecting a soft lens material into a second female die, inserting the male die and the first buckling material, and heating and polymerizing in a thermotank; and turning with a turning method, polishing and separating. In the soft lens and hard lens combined contact lens provided by the invention, the hard lens and the soft lens of the contact lens are combined together, the defects of the soft lens and the hard lens are overcome, and the soft lens and hard lens combined contact lens is comfortable for wearing, has short adaptation time, clear corrected visual acuity, better corneal astigmatism correcting effect than an ordinary soft lens and high oxygen permeation performance, and can be worn frequently.
Description
Technical field
The present invention relates to a kind of contact lenses and manufacturing approach thereof, be specifically related to the contact lenses and the manufacturing approach thereof of a kind of soft lens and hard mirror combination.
Background technology
The soft contact lens that present stage uses has good plasticity because the water wettability of material and quality are soft, thereby comfortable wearing, and adaptation time is short.Owing to need not to adapt to repeatedly, so can supply intermittence to wear.Diameter is bigger, and lens edge is positioned under the eyelid, has avoided the easiest factor of causing foreign body sensation, i.e. the friction of eyelid and lens edge, and eyeglass can not drop out from intraocular.The edge of eyeglass tightly is attached to outside the corneoscleral junction, is difficult for the people for discovering, and is specious.But its sphere soft lens is corrected the corneal astigmatism weak effect.Lens surface polarity is strong, adsorbs the sediment in the tear easily, and the composition of pathogenic microorganisms and conditioning liquid is prone to cause ocular complication.The oxygen permeability of eyeglass is poor, can not wear mostly and spend the night.
The good permeability of the hard contact lens that present stage uses, it is clear to correct defects of vision, and the effect of correcting corneal astigmatism is good than soft lens, durable.Tear when twinkling under the eyeglass has the circulation of row's suction preferably, helps the discharge of metabolism.There is the partly ventilative hard mirror of good oxygen permeability can often wear use.But its poor plasticity, wettability is poor, and it is comfortable to wear too late soft lens, needs certain adaptation time.Optic diameter is less than cornea, and the drying property epithelial damage takes place Gu Jiaomobaoluqu easily.
Summary of the invention
The object of the invention is exactly deficiency and the shortcoming that will eliminate above-mentioned prior art; The contact lenses that a kind of premium properties that can keep soft lens and hard mirror overcome not enough separately a kind of soft lens and hard mirror combination again and the manufacturing approach of this soft lens and the contact lenses of hard mirror combination are provided.
For achieving the above object; The present invention provides the contact lenses of a kind of soft lens with hard mirror combination, comprises the core of optical region, around the peripheral part of core; It is characterized in that said optical centre partly is hard contact lens mirror body, peripheral part is a soft contact lens mirror body.
Preferably, the diameter of said core is greater than the diameter of pupil.
Preferably, said contact lenses also comprise the joint portion of said core and peripheral part, and said joint portion comprises the protuberance of core and the recess of peripheral part.
A kind of soft lens comprises with the manufacturing approach of the contact lenses of hard mirror combination
In first die, inject hard mirror material, insert the punch polymerization and form button material for the first time;
In second die, inject the soft lens material, insert punch and detain material, heated polymerizable in constant temperature oven for the first time;
Carry out obtaining after turning, polishing, the separation contact lenses of soft lens and hard mirror combination with method for turning.
Beneficial effect of the present invention:
The contact lenses of a kind of soft lens provided by the invention and hard mirror combination combine the hard mirror and the soft lens of present contact lenses; Overcome soft lens and hard mirror deficiency separately, made comfortable wearing of the present invention, adaptation time is short; It is clear to correct defects of vision; The more common soft lens of effect of correcting corneal astigmatism is good, has good oxygen permeability, can often wear use.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present invention;
Fig. 2 cuts the sectional view that obtains open for Figure 1A of the present invention-A direction;
Fig. 3 is the local enlarged diagram of the M portion of Fig. 2.
Wherein 1-core, 2-peripheral part, 3-protuberance, 4-recess.
Embodiment
Like the contact lenses of Fig. 1 to a kind of soft lens shown in Figure 3 and hard mirror combination; The core 1 that comprises optical region; Around the peripheral part 2 of core 1, core 1 is a hard contact lens mirror body, and peripheral part 2 is a soft contact lens mirror body; The diameter of core 1 is greater than the diameter of wearer's pupil, and the core 1 of contact lenses of the present invention and the joint portion of peripheral part 2 are made up of the protuberance 3 of core and the recess 4 of peripheral part.
The contact lenses of soft lens provided by the present invention and hard mirror combination are through following method manufacturing: in first die, inject hard mirror material, insert the punch polymerization and form for the first time button and expect; In second die, inject the soft lens material, insert punch and detain material, heated polymerizable in constant temperature oven for the first time; Carry out obtaining after turning, polishing, the separation contact lenses of soft lens and hard mirror combination with method for turning.
The contact lenses of a kind of soft lens provided by the invention and hard mirror combination combine the hard mirror and the soft lens of present contact lenses; Overcome soft lens and hard mirror deficiency separately, made comfortable wearing of the present invention, adaptation time is short; It is clear to correct defects of vision; The more common soft lens of effect of correcting corneal astigmatism is good, has good oxygen permeability, can often wear use.
Above-described only is the preferred embodiments of the present invention.Should be understood that for the person of ordinary skill of the art, under teachings provided by the present invention,, can also make other equivalent modifications and improvement, also should be regarded as protection scope of the present invention as the common practise of this area.
