Patent Claims:	1. A method for treating Demodex blepharitis, comprising: topically administering directly to an ocular surface of one or more eyes of a human patient in need of treatment thereof an effective amount of an isoxazoline parasiticide, formulated into an ophthalmic composition, the ophthalmic composition further comprising a pharmaceutically acceptable vehicle, wherein the ophthalmic composition comprises an eye drop, wherein the isoxazoline parasiticide is the sole active ingredient of the ophthalmic composition, and wherein the isoxazoline parasiticide comprises lotilaner. 2. The method of claim 1, wherein about 0.30% by weight of the isoxazoline parasiticide with respect to the total weight of the composition is administered. 3. The method of claim 1, wherein between about 0.20% and about 0.40% by weight of the isoxazoline parasiticide with respect to the total weight of the composition is administered. 4. The method of claim 1, wherein the ocular surface comprises at least one of the conjunctiva or cornea of the one or more eyes of the patient. 5. The method of claim 1, wherein the ophthalmic composition comprises castor oil. 6. A method for treating Demodex blepharitis, comprising: topically administering directly to one or more of the eye, eyelids, or eyelashes of a human patient in need of treatment thereof an effective amount of an isoxazoline parasiticide, formulated into an ophthalmic composition further comprising a pharmaceutically acceptable vehicle, wherein the ophthalmic composition comprises an eye drop, and wherein the isoxazoline parasiticide comprises lotilaner. 7. The method of claim 6, wherein the patient's eyes are closed upon topically administering the ophthalmic composition, such that the composition contacts orifices of Meibomian glands of the patient and outside of eyelid margins of the patient. 8. The method of claim 6, wherein from about 0.15% to about 0.40% by weight of the isoxazoline parasiticide with respect to the total weight of the composition is administered. 9. The method of claim 6, comprising topically administering the ophthalmic composition at least once daily for at least about 4 weeks. 10. The method of claim 6, comprising topically administering the ophthalmic composition at least twice daily for at least about 6 weeks. 11. A method for treating an ocular Demodex infestation, comprising: topically administering directly to an ocular surface of one or more eyes of a human patient in need of treatment thereof, an effective amount of an isoxazoline parasiticide, formulated into an ophthalmic composition further comprising a pharmaceutically acceptable vehicle, wherein the ophthalmic composition is sterile, wherein the ophthalmic composition comprises an eye drop, wherein the ophthalmic composition does not comprise tea tree oil, and wherein the isoxazoline parasiticide comprises lotilaner, wherein topically administering occurs twice daily for at least 4 weeks. 12. The method of claim 11, wherein the isoxazoline parasiticide is the sole active ingredient of the ophthalmic composition. 13. The method of claim 11, wherein the ocular Demodex infestation comprises blepharitis. 14. The method of claim 11, wherein the ocular Demodex infestation comprises ocular rosacea. 15. The method of claim 11, wherein the ocular Demodex infestation comprises Meibomian gland dysfunction. 16. The method of claim 11, wherein the ocular Demodex infestation comprises ocular surface disease. 17. The method of claim 11, wherein the ocular Demodex infestation comprises dry eye disease. 18. The method of claim 11, wherein the ocular Demodex infestation comprises madarosis. 19. A method for treating an ocular Demodex infestation, comprising: topically administering to an ocular surface of one or more eyes of a human patient in need of treatment thereof, an effective amount of an isoxazoline parasiticide, formulated into an ophthalmic composition further comprising a pharmaceutically acceptable vehicle, wherein the ophthalmic composition comprises an eye drop, and wherein the isoxazoline parasiticide comprises lotilaner. 20. The method of claim 19, comprising administering between about 25 microliters and about 50 microliters of the eye drop to the patient at least one time daily. 21. The method of claim 19, comprising administering between about 25 microliters and about 50 microliters of the eye drop to the patient twice daily for at least six weeks. 22. The method of claim 19, wherein the ocular Demodex infestation comprises blepharitis or Meibomian gland dysfunction. 23. The method of claim 19, wherein the ocular Demodex infestation comprises blepharitis or Meibomian gland dysfunction, wherein about 0.30% by weight of the isoxazoline parasiticide with respect to the total weight of the composition is administered, wherein the isoxazoline parasiticide is the sole active ingredient of the ophthalmic composition, wherein the ophthalmic composition does not comprise tea tree oil, wherein the ophthalmic composition further comprises hydrogenated castor oil, and wherein the method further comprises administering between about 25 microliters and about 50 microliters of the eye drop to the patient two times daily for at least six weeks.
