The National Institutes of Health defines radiation sickness and related symptoms that result from excessive exposure to ionizing radiation as illness. This is the type of radiation that results in immediate chemical effects on the tissue. Different types of beams that cause ionizing radiation are used at the dentist's office, among other medical departments, for both testing and treatment purposes.
Radiation poisoning can easily affect an eye that is exposed to just a small amount of it. Radiation poisoning may result from a single large exposure to the harmful radiation or a number of small exposures over an extended period. When the eye is exposed, there is damage the lens, leading to such complications as cataracts and other types of opacity. This is why lead glasses should be used in such places.
A dentist may need to use an x-ray machine to determine problems that lurk beneath the surface. Dental films are placed in the mouth, which are steadied by biting on small tabs, to allow the dentist to position the x-ray beams. Some devices are small and the dentist has to take a series of pictures, while others capture all of the teeth in a single picture.
Dentists and their assistants need leaded eyewear, to protect them against the radiation originating from diagnostic imaging machines, including the simple intraoral dental units. These special glasses absorb radioactive particles and scatter some away from the eyes. They protect the eyes against around 98% of the radiation they are exposed to.
Lead has strong resistance and high density that help it protect against radiation damage.
The lead equivalency of the lenses must be at par with or exceed industry standards to ensure adequate protection. In the medical industry, the standard equivalency is .75 mm.
Visibility is important during dental procedures, and this is the next consideration when choosing the right lead glasses. If the wearers use prescription spectacles, they should preferably use radiation goggles that accommodate their spectacles. The frame needs to fit nicely on the side of the head or have side shields for better protection.
The eye is among the most sensitive parts of the body. When dentists and their assistants undertake radiographic imaging procedures, they are exposed to ionizing radiation, particularly in the eyes. In most practices, they are required to wear lead glasses to protect themselves. This eyewear is recommended for every procedure involving x-rays and gamma rays.
There are different types of leaded eyewear that suit different styles. This way, the wearers will still remain fashionable and comfortable while receiving the necessary protection.
