Abstract
A manufacture method for colored soft contact lenses successively comprises the following steps: 1) injection molding of a mould; 2) preparation of a lens outer surface layer; 3) preparation of a lens color layer; 4) preparation of a lens inner surface layer; and 5) parting, hydration, detection, packaging and disinfection of the lens. The color layer is disposed in the middle of a soft contact lenses material non-optical area interlayer; the prepared colored soft contact lenses have the advantages of sufficient hydration, complete unfoldment, natural transition of radian and corners, intact combinations among the lens outer surface layer, an ink layer and the lens inner surface layer, improved hydrophilia and moisture retention, and dryness preventing effect on eyes; and therefore the purpose of safe and comfortable wearing for consumers is realized.
Description
Technical field
The present invention relates to a kind of colored soft contact lens and preparation method thereof.Be exactly that a kind of coloured colorant is coated with is placed in the middle of the soft contact lens material specifically, and can change the colored soft contact lens and preparation method thereof of hydrophily, moisture retention and the raising optical zone definition of soft contact lens extexine.
Background technology
Soft colored contact lens the earliest occurs in order to help the injured people of eyes to hide the eyes flaw, is widely applied to afterwards in the film cosmetic.Along with improving constantly of living standards of the people, the colored soft contact lens with multiple functions such as vision correction and beauty treatments is used in daily life widely.
Colored soft contact lens can be divided into three kinds by the positional structure of color layer: first kind is the inner surface non-optical zones that color layer is coated on the soft contact lens material; Second kind is the outer surface non-optical zones that color layer is coated on the soft contact lens material.These two kinds of methods all are the surfaces that color layer is coated on the soft contact lens material, and color layer will directly contact with cornea or eyelid when wearing like this, causes discomfort when wearing, and simultaneously color layer also can cause more or less injury to eyes; The third is that color layer places in the middle of the soft contact lens material non-optical zones interlayer, and this way has overcome above two kinds shortcoming, makes the user more comfortable safer in wearing process.Relevant for the patent of this respect, proposed about saying and corresponding preparation method and the material composition of color layer in the middle of eyeglass before.Wherein, eyeglass is three layers on bottom, intermediate layer and top layer, in the middle of the intermediate layer that only is positioned at contact lenses iris district is coated on by bottom and top layer.The material that is exactly bottom and top layer in addition is consistent, is made up of thermosetting or thermoplasticity monomer, initator, crosslinking agent.
Producer produces sandwich colored soft contact lens by this way mostly now.
Optical zone just is made up of ground floor and the 3rd stacked adding like this.Because the moulding of eyeglass stage feeding polymerization, two-layer molecular structure can be different, and two-layer contact-making surface also can produce great number of issues such as oxide layer, can cause eyeglass focal power variation or unintelligible etc.Next is that the ectonexine material is the same, and the eyeglass surfaces externally and internally material characteristic of making is similar, and the outer surface dehydration is greater than inner surface when wearing, and eyeglass can follow eyelid to move when nictation, causes the eyes sensation of dryness.Therefore, need a kind of novel colored soft contact lens and preparation method thereof, and this method should place in the middle of the soft contact lens material non-optical zones interlayer by color layer, and focal power is more clearly arranged again, the effect that improves hydrophily, moisture retention also to be arranged, prevent that eyes are dry and astringent.Finally reach the purpose that makes consumer's safe wearing comfortable.
Summary of the invention
At above defective, the invention provides a kind of method of novel colored soft contact lens, be that the color layer with colored soft contact lens places in the middle of the soft contact lens material non-optical zones interlayer, allow the comfortable purpose of consumer's safe wearing.
Technical scheme of the present invention realizes in the following manner: a kind of preparation method of colored soft contact lens may further comprise the steps successively: the 1) injection mo(u)lding of mould; 2) making of eyeglass extexine; 3) making of eyeglass color layer; 4) making of eyeglass interior surface layers; 5) branch mould, hydration, inspection, encapsulation, the sterilization of eyeglass; It is characterized in that:
