Although<unk> s may be seen with ophthalmoscopes, slit lamp microscopes provide higher magnification which allow for a more thorough evaluation. To aid in viewing, a fluorescein stain that fills in the corneal defect and glows with a cobalt blue-light is generally instilled first. A<unk> reful search should be made for any foreign body, in particular looking under the eyelids. Injury following use of hammers or power-tools should always raise the possibility of a penetrating foreign body into the eye, for which urgent ophthalmology opinion should be sought. Prevention Prevention is the best method to avoid recurrence of<unk> s. Protective eyewear should be worn by people who work with hazardous machinery, metal, wood, or chemicals, as well as those who perform yard work or participate in certain contact sports. The appropriate type of protective eyewear depends on the specific circumstances, but all should provide shielding, good visibility, and a comfortable fit. Some examples include polycarbonate glasses or goggles, plastic safety glasses, face shields, and welding helmets. Specifically, welders should use a helmet with a lens that blocks UV light to avoid UV keratitis. It is important to notice that people with one eye are especially vulnerable to potentially blinding injuries, and should pay special attention to protecting their eyes. In these<unk> ses, protective eyewear<unk> n ensure some degree of safety while also allowing people to participate in their normal day-to-day activities. Ensuring both a proper contact lens fit and the compliance of the person with<unk> re measures<unk> n prevent contact lens-related complications. As it has been stated previously, these<unk> n<unk> use both mechanic damage to the cornea and be a risk factor for the development of microbial keratitis. Thus, an emphasis should be placed on reducing lens contamination by using effective disinfecting solutions, as well as antimicrobial contact lenses and<unk> ses. It is important to avoid swimming with contact lenses, because this increases the frequency of bacterial infections, primarily from Staphylococcus epidermidis and other organisms found in contaminated water. Finally, people who use contact lenses<unk> n also avoid both mechanical and infectious trauma by not using contacts beyond the length of their intended use.
