Description
Technical field
The present invention relates to contact lens field, especially a kind of contact lens polishing fluid and preparation method thereof.
Background technology
RGP is a kind of hard corneal contact lens that can provide good optical qualities, is used for the diseases such as treatment keratoconus, high myopia, heterometropia clinically, is also increasingly being used to treatment Children and teenager myopia in recent years.Ortho-K is as a kind of special RGP eyeglass, and its outstanding advantage is for " orthopedic ", namely improves eyesight by changing cornea set form.Its orthopedic effect is similar to laser surgey, but is provisional and recoverable with laser surgey unlike the effect that Ortho-K produces, and is effective reversibility methods for the treatment of that No operation removes spectacles.Effective risk reducing the not reversibility damage brought of performing the operation.Along with the intensification gradually that people are familiar with RGP eyeglass, following RGP market will welcome the growth of blowout formula.
Polishing is as the vital technique making Ortho-K, and the performance of its polishing fluid used directly has influence on the quality of eyeglass.Although currently used oiliness polishing system can obtain good polishing effect, following problem can be brought simultaneously:
(1) bad dispersibility of inorganic polishing powder in organic system, brings difficulty for polishing powder is dispersed in system, even if the surface treatment carrying out in advance to it, still fundamentally can not improve the dispersiveness of polishing powder in organic system.Because polishing powder is easily agglomerated into without effective dispersion the effect that larger particle directly has influence on polishing, increase the probability that lens surface forms cut;
(2) oleaginous system cost is high, and for subsequent disposal eyeglass brings great inconvenience, simultaneously discarded polishing fluid contaminate environment, does not meet the theory of environmental protection;
(3) polishing fluid of organic system considerably increases production cost, and the organic compound such as methyl alcohol have higher toxicity, proposes higher requirement to production environment.
Summary of the invention
The object of the present invention is to provide a kind of contact lens polishing fluid and preparation method thereof, this polishing fluid can be used for contact lens surface finish, is specially adapted to the polished finish of contact lens,hard material eyeglass.This polishing fluid polishing performance is excellent, with low cost, environmental protection, and preparation method's technique is simply controlled.
