Disclosed herein is a baffle for regulating air flow around an object. The baffle can be of unitary construction and can be made by a single shot injection molding process. The baffle can have an edge portion that is more flexible than the base portion. The baffle has also can have a base portion with a base portion thickness and an edge portion with an edge portion thickness that is less than the base portion thickness. A method of making a baffle by an injection molding process is also disclosed.

METHOD FOR MAKING PHOTOCHROMIC CONTACT LENSES

Described herein is a method for producing photochromic silicone hydrogel contact lenses in a relatively efficient and consistent manner from a polymerizable composition under a controlled thermal curing scheme. The main polymerizable components in the polymerizable composition are a high radical-reactive hydrophilic (meth)acrylamido monomer, a high radical-reactive siloxane-containing (meth)acrylamido monomer, and a polysiloxane vinylic crosslinker(s) free of low-reactive ethylenically unsaturated group as the main crosslinker. The thermal free radical initiator having a 10 hour half-life temperature (T.sub.10hλ) of from about 50° C. to about 90° C. The controlled thermal curing scheme includes maintaining a first curing temperature of from about (T.sub.10hλ−20)° C. to about T.sub.10hλ° C. for a first curing time and maintaining a second curing temperature of from about (T.sub.10hλ+10)° C. to about (T.sub.10hλ+35)° C. for a second curing time.
