9 . The secondary contact lens case of claim 1 , wherein said indicator comprises a reactive ink that changes colors after a designated amount of exposure to an initiator.
10 . The secondary contact lens case of claim 9 , wherein said initiator comprises at least one of air, water, heat, or light.
11 . The secondary contact lens case of claim 1 , wherein said indicator is formed as an integral part of said secondary case.
12 . The secondary contact lens case of claim 1 , wherein said indicator is applied to said secondary case after said secondary case is formed.
13 . The secondary contact lens case of claim 1 , wherein said case further comprises at least one cap; wherein said indicator is disposed on said cap.
14 . The secondary contact lens case of claim 1 , wherein said case further comprises a base, wherein said indicator is located on said base.
15 . The secondary contact lens case of claim 1 , wherein said case further comprises at least one well, wherein said indicator is located on said well.
16 . The secondary contact lens case of claim 1 , wherein said case further comprises first and second bottom members and corresponding caps.
17 . The secondary contact lens case of claim 16 , wherein said first and second bottom members further comprise at least one of substantially different geometries, sizes, or physical appearances.
18 . The secondary contact lens case of claim 16 , wherein each of said first and second bottom members further comprises threading complementary to said corresponding caps.
19 . The secondary contact lens case of claim 18 , wherein said complementary threads of said first and second bottom members comprise at least one of substantially different sizes, pitches, or gaps.
20 . A secondary contact lens case comprising:
at least one bottom member having a well, and a wall rising above said well and ending in a top rim defining an opening;
a base configured to stabilize said case;
one or more caps, corresponding to said at leas one bottom member and configured to completely cover said top rim; and so as to provide a leak-proof enclosure;
an indicator on said case configured to indicate when said secondary contact lens case expires.
21 . The secondary contact lens case of claim 20 , wherein said indicator is located on said cap.
22 . The secondary contact lens case of claim 20 , wherein said indicator is located on said base.
23 . The secondary contact lens case of claim 20 , wherein said indicator is located underneath said well.
24 . The secondary contact lens case of claim 20 , wherein said cap is configured to provide a leak-proof enclosure.
25 . The secondary contact lens case of claim 20 , wherein said case comprises at least two of said bottom members.
26 . The secondary contact lens case of claim 25 , wherein said bottom members are different in size or shape.
27 . The secondary contact lens case of claim 25 , wherein said bottom members and caps further comprise complementary threading.
28 . The secondary contact lens case of claim 27 , wherein said bottom members' threads are substantially different in size, pitch, or gap.
29 . A method of fabricating a secondary contact lens case comprising:
forming a secondary contact lens case;
wherein said case includes an expiration indicator.
30 . The method of claim 29 , wherein said indicator is integrally formed or molded on the surface of said case during a manufacturing process.
31 . The method of claim 29 , wherein said indicator is formed on said case post manufacture.
32 . The method of claim 29 , wherein said indicator is formed by a process selected from the group of inkjet printing, laser printing, single shot molding, application of a sticker, or any combination thereof.
33 . The method of claim 29 , wherein said indicator is formed by a two shot process.
34 . The method of claim 33 , wherein a second shot forms the indicator from a second material that provides color or contrast against a first material from a first shot.
35 . The method of claim 29 , wherein said case further comprises a substantially transparent base.
36 . The method of claim 35 , wherein said indicator is formed in reverse on a bottom of said base.
