In order to compensate for this drawback, attempts have subsequently been made to make the surface hydrophilic, for example by corona discharge or plasma treatment. However, hydrophilicity does not have stability over a long period of time. After a relatively long period of wear, contact lenses lose their wettability and therefore their conformability.

>j&^66141. A process has now been found for the production of objects for contact glasses, characterized in that the vinyl monomers up to the point are polymerized in the presence of a hookal initiator.

Peroxides, such as, for example, nobennorberoxide and cupuryl peroxide, or azo compounds, such as, for example, nonitrile azoisobutyrate, can be used, for example, as physical initiators.

Of course, it is also possible to initiate polymerization with light.

Polymerization can be carried out in a plate chamber, a plastic tube or a plastic dish.
b) It is possible to carry out the process by a so-called bulk polymerization method.

A preferred sandwiching according to the invention is to carry out the polymerization of the components in a pan made of polyol/fins, such as polyethylene, polypropylene, polymethylpentene-1, polyamide or polyacecool. This 111 [i, is an appropriate rank for an object for contact glasses.

Polymerization can also be carried out with the addition of solvents such as ethylene glycol, water or ethanol. The solvent can be washed off later with water if necessary.

The copolymer can also be crosslinked during or after the undercarriage.

Crosslinking can be carried out in a manner known per se, for example by the action of irradiation of the prepared copolymer with energetic radiation, e.g. electron beam radiation, or by crosslinking with at least two olefinic unsaturations during the copolymerization. 0.01 to 6% by weight, preferably 0.1 to 5% by weight, and particularly preferably 0.2 to 1% by weight.

Suitable crosslinkers can be, for example, (meth)acrylate crosslinkers and/or vinyl or allyl crosslinkers.

In addition to the (meth)acryle -F group, at least 66
(Meth)acrylate crosslinkers containing unsaturated groups or different olefin A unsaturated groups are known per se. These include 7-acrylates or methacrylates of polyfunctional alcohols, such as ethylene glycol methacrylate, propylene glycol no methacrylate,

: Preferably used in the trivial ratio of i.

Contact ophthalmic objects with a high degree of transparency and light stability are produced very advantageously by using two crosslinking agents in combination (as described above). The material obtained in this way has virtually no components that can be extracted with water! It does not include

The copolymer is generally molded into a random shape, and the copolymer has a composition of 1
It has a network structure.

Depending on the type of phosphoroxane-(meth)acrylic monofoam, the glass transition temperature ranges from -80 to +100"C. Linear polysiloxane residues give polymers with low glass transition temperatures, and therefore A flexible, elastomeric contact@mirror object results.

(Meth)acrylic acid molecules with branched polyoxyaxane residues give polymers with a good lath rearrangement, thus producing semi-solid to hard contact eyewear objects.

Depending on the proportion of the constituent units of the wood-loving dosing body in the copolymer, the water absorption capacity of the copolymer can vary widely, for example in the range of 2 to 70% of the hydrated state, - Compared to ordinary soft lenses with sharp edges, the lenses produced according to the present invention have a lower water absorption performance, which makes it possible to achieve the desired comfort level by using soft lenses with corresponding oxygen permeability. It has the advantage of being able to prepare sushi in such a way that it feels comfortable to wear.

A particular advantage of the contact glasses object according to the invention is its good wettability, which is maintained even after wearing. Common contact spectacle objects, especially lenses based on polysilicon methacrylate, lose their moisture decay properties after several months of wear and require subsequent surface treatment. By reducing the deposits on the surface of the contact glasses object, the material properties of the high gas permeability polymer are maintained. Visual disturbance and Fl
