Finally, many commercial radiator antifreeze products have fluorescein added to enable radiator leaks to be detected using a Woods lamp. Following ingestion of antifreeze products containing ethylene glycol and fluorescein, a Woods lamp may reveal fluorescence of a persons mouth area, clothing, vomitus, or urine which can help to diagnose poisoning. Prevention
Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available, and are generally considered safer to use, as it possesses an unpleasant taste in contrast to the perceived "sweet" taste of toxic ethylene glycol-based coolants, and produces only lactic acid in an animals body, as their muscles do when exercised.When using antifreeze products containing ethylene glycol, recommended safety measures include:

Cleaning up any spill immediately and thoroughly. Spills may be cleaned by sprinkling cat litter, sand or other absorbent material directly on the spill. Once fully absorbed, while wearing protective gloves, the material may be scooped into a plastic bag, sealed and disposed. The spill area may be scrubbed with a stiff brush and warm, soapy water. The soapy water is not recommended to be drained in a storm drain. Checking vehicles regularly for leaks. Storing antifreeze in clearly marked original sealed containers, in areas that are inaccessible to pets or small children. Keeping pets and small children away from the area when draining the car radiator. Disposing of used antifreeze only by taking to a service station. If antifreeze is placed in toilets, ensuring the lid is down and the door closed.
Amaurosis (Greek meaning darkening, dark, or obscure) is vision loss or weakness that occurs without an apparent lesion affecting the eye. It may result from either a medical condition or excess acceleration, as in flight. The term is the same as the Latin gutta serena, which means, in Latin, drop clear (or drop bright). Gutta serena is a condition of partial or complete blindness with a transparent, clear pupil. This term contrasts with suffusio nigra which means, in Latin, suffusion dark,  indicating partial or complete blindness with a dark pupil, e.g., a cataract. Milton, already totally blind for twelve years (some scholars think from retinal detachment; others have diagnosed glaucoma) by the time he published Paradise Lost, refers to these terms in Book 3, lines 25–26. Types
Lebers congenital amaurosis is an inherited disease resulting in optic atrophy and secondary severe vision loss or blindness. It was first described by Theodore Leber in the 19th century.Amaurosis fugax (Latin: fugax meaning fleeting) is a temporary loss of vision in one eye caused by decreased blood flow (ischemia) to the retina. It may also be caused by embolization from atherosclerotic plaques in the ipsilateral (same side) internal carotid artery. It is a type of transient ischaemic attack (TIA). Those experiencing amaurosis usually experience complete symptom resolution within a few minutes. In a small minority of those who experience amaurosis, stroke or permanent vision loss results. Diabetes, hypertension and smoking are factors known to increase the risks of suffering this condition.
