The present invention pertains to methods of using certain 1-di-isopropyl-phosphinoyl-alkanes as described herein (DIPA-1-7, DIPA-1-8, and DIPA-1-9, collectively referred to herein as “DIPA compounds”) for the treatment of ocular discomfort that is caused by eye strain; eye surgery; an airborne irritant or pollutant that interacts with the eye surface; heat discomfort; extended wear of contact lenses; excessive exposure to the sun; asthenopia; conjunctivitis; or a dry eye syndrome. The present invention also pertains to pharmaceutical compositions comprising such compounds, and media contain those pharmaceutical compositions.

The present invention relates to a composition comprising an aramid for a soft contact lens and a method for manufacturing a soft contact lens using same and, more specifically, to a composition for a soft contact lens and a method for manufacturing a soft contact lens using same, the composition comprising a colorless and transparent aramid polymer, a hydrophilic monomer, a curing agent, and an initiator. The composition comprising an aramid for a soft contact lens according to the present invention provides a soft lens that, compared with existing contact lenses, has less irritation and enables extended wear time due to an excellent water content and high oxygen permeability and is easily handled due to excellent mechanical strength.
