6. The ophthalmic composition of claim 1 , wherein a storage condition has a storage temperature of from about 2° C. to about 10° C. or from about 16° C. to about 26° C.
7. The ophthalmic composition of claim 1 , wherein the atropine or atropine sulfate is present in the composition at a concentration of one of: from about 0.001 wt % to about 0.04 wt %, from about 0.001 wt % to about 0.03 wt %, from about 0.001 wt % to about 0.025 wt %, from about 0.001 wt % to about 0.02 wt %, from about 0.001 wt % to about 0.01 wt %, from about 0,001 wt % to about 0.008 wt %, or from about 0.001 wt % to about 0.005 wt %.
8. The ophthalmic composition of claim 1 , wherein the ophthalmic composition further comprises an osmolarity adjusting agent.
9. The ophthalmic composition of claim 8 , wherein the osmolarity adjusting agent is sodium chloride.
10. The ophthalmic composition of claim 1 , wherein the ophthalmic composition further comprises a preservative.
11. The ophthalmic composition of claim 10 , wherein the preservative is selected from benzalkonium chloride, cetrimonium, sodium perborate, stabilized oxychloro complex, SofZia, polyquaternium-1, chlorobutanol, edetate disodium, polyhexamethylene biguanide, or combinations thereof.
12. The ophthalmic composition of claim 1 , wherein the ophthalmic composition further comprises a buffer agent.
13. The ophthalmic composition of claim 12 , wherein the buffer agent is selected from borates, borate-polyol complexes, phosphate buffering agents, citrate buffering agents, acetate buffering agents, carbonate buffering agents, organic buffeting agents, amino acid buffering agents, or combinations thereof.
14. The ophthalmic composition of claim 1 , wherein the ophthalmic composition is essentially free of procaine and benactyzine, or pharmaceutically acceptable salts thereof.
15. The ophthalmic composition of claim 1 , wherein the ophthalmic composition has a dose-to-dose atropine or atropine sulfate concentration variation of one of: less than 50%, less than 40%, less than 30%, less than 20%, less than 10%, or less than 5%.
