Leaded eyewear is worn by medical professionals to reduce the risk of exposure to electromagnetic radiation in their work. Doctors, nurses and technologists who work around radiation require this protection as studies indicate that even a minor exposure to radiation can have a harmful effect on the eyes. Not protecting the eyes for even the shortest period of time can lead to cataracts, as the eye is very vulnerable to radiation exposure. Radiation exposure can cause a damage to tear ducts resulting in dry eyes that are more prone to infection. Retinal damage, vision loss, glaucoma and tumor growth can also be attributed to this type of exposure in the eye.
In the past, leaded eyewear was heavy and bulky and provided little comfort. Medical practitioners who wore prescription glasses were required to wear protective eyewear that fit over their glasses. Today, there are many choices available and it is quite easy to find lightweight, well fitting and even stylish options. Prescription lens wearers can have their radiation glasses specially made with their prescription so they no longer need to wear two sets of glasses during periods of exposure.
There are three main points to consider when purchasing leaded eyewear. The first, of course, is the level of protection provided. Leaded eyewear is designed to scatter radiation away from the eyes and for this to be accomplished, the front lenses should be at least.75mb. Side or peripheral protection is equally important and side lenses should be.5mm or greater.
The next thing to consider is the comfort of the eyewear. The protective glasses should feel like well-fitting sunglasses. The protective eyewear should stay in place and not slide down the nose when looking at the floor. When sampling pairs, it is important to check for pressure on the nose or under the eyes. If there is noticeable pressure, the eyewear may be too heavy for prolonged use.
Finally, the leaded eyewear must be well constructed. The frames should be adjustable, as the fit may change after several uses. The frames and lenses should be durable enough to withstand drops to the floor and the lenses should be scratch resistant. Look for leaded eyewear that comes with cleaning instructions and a solid warranty against damage and defects.
Radiation exposure builds up in the human body, so any unprotected exposure can be harmful. Many of the effects can go unseen for weeks, months or even years, so it is best for medical professionals to take no chances with an organ as vital as the eye.
