Silicone hydrogel contact lenses

A silicone hydrogel contact lens, comprising a silicone hydrogel bulk material which comprises:

• (1) first repeating units of at least one siloxane-containing vinylic monomer including 0 to 10 first H-donor moieties,
• (2) second repeating units of at least one first polysiloxane vinylic crosslinker which has second H-donor moieties and is a compound of formula (1)
• in which
• υ1 is an integer of from 30 to 500 and ω1 is an integer of from 1 to 75, provided that ω1/υ1 is from 0.035 to 0.15,
• X01 is O or NRn in which Rn is hydrogen or C1-C10 alkyl,
• Ro is hydrogen or methyl,
• R2 and R3 independently of each other are a substituted or unsubstituted C1-C10 alkylene divalent radical or a divalent radical of —R5—O—R6— in which R5 and R6 independently of each other are a substituted or unsubstituted C1-C10 alkylene divalent radical,
• R4 is a monovalent radical of formula (4),
• R10 is ethyl or hydroxymethyl,
• (3) third repeating units of at least one hydrophilic N-vinyl amide monomer,
• (4) optionally fourth repeating units of at least one second polysiloxane vinylic crosslinker having 0 to 35 fourth H-donor moieties, and
• (5) fifth repeating units of a blending vinylic monomer selected from the group consisting of a C1-C10 alkyl (meth) acrylate, cyclopentylacrylate, cyclohexylmethacrylate, cyclohexylacrylate, isobornyl (meth) acrylate, styrene, 4,6-trimethylstyrene, t-butyl styrene, trifluoroethyl (meth) acrylate, hexafluoro-isopropyl (meth) acrylate, hexafluorobutyl (meth) acrylate, and combinations thereof,
• wherein the second repeating units of said at least one first polysiloxane vinylic crosslinker are different from the fourth repeating units of said at least one second polysiloxane vinylic crosslinkers, wherein the first, second, and fourth H-donor moieties independent of one another are hydroxyl groups, carboxyl groups, amino groups of —NHR°, amino linkages of —NH—, amide linkages of —CONH—, urethane linkages of —OCONH—, or combinations thereof, wherein R° is H or a C1-C4 alkyl,
• wherein the silicone hydrogel bulk material comprises at least 8.8 mmoles of the third repeating units per gram of all the first, second and fourth repeating units in total and at least 0.11 meqs of all the first, second, and fourth H-donor moieties in total per gram of the third repeating units,
• wherein the silicone hydrogel contact lens has an oxygen permeability of at least 50 barrers, an elastic modulus of from 0.2 MPa to 1.5 MPa, and an equilibrium water content of from 40% to 70% by weight and is inherently wettable as characterized by having a water-break-up-time of at least 10 seconds and a water contact angle by captive bubble of 80 degrees or less without being subjected to any post-curing surface treatment.
