There is no valid scientific reason to use DMSO on the eye and its use is potentially harmful. This is from Wikipedia:
Toxicity[edit]
DMSO is a solvent with a median lethal dose higher than ethanol (DMSO: LD50 Oral-Rat-14,500 mg/kg,[29] Ethanol: LD50 Oral-Rat-7,060 mg/kg [30]).
Early clinical trials with DMSO were stopped because of questions about its safety, especially its ability to harm the eye. The most commonly reported side effects include headaches and burning and itching on contact with the skin. Strong allergic reactions have been reported.[full citation needed] DMSO can cause contaminants, toxins, and medicines to be absorbed through the skin, which may cause unexpected effects. DMSO is thought to increase the effects of blood thinners, steroids, heart medicines, sedatives, and other drugs. In some cases this could be harmful or dangerous.[26] It is a developmental neurotoxin.[31] In Australia it is listed as a schedule 4 poison, and a company has been prosecuted for adding it to products as a preservative.[32]
Because DMSO easily penetrates the skin, substances dissolved in DMSO may be quickly absorbed. Glove selection is important when working with DMSO. Butyl rubber, fluoroelastomer, neoprene, or thick (15 mil) latex gloves are recommended.[33] Nitrile gloves, which are very commonly used in chemical laboratories, may protect from brief contact but have been found to degrade rapidly with exposure to DMSO.[34]
