Method for transiently wetting lens molds in production of contact lens blanks to reduce lens hole defects |
| 摘要 |
Hydrophilic contact lens molds are transiently modified to provide a water dynamic contact angle equal to or less than 100 DEG by treatment with a wetting agent which may be water or a surfactant composition which provides a mold surface having a water wetting force of at least 70 mg to afford a reduction in lens hole defects in hydrophilic contact lens manufacture.
