Even the smallest exposure to x-ray radiation to the eye can cause radiation poisoning. The symptoms of radiation poisoning include weakness, nausea and hair loss. This is why lead glasses should be worn at all times when working around radiation. These glasses are able to block a significant amount of radiation that comes from diagnostic imaging machines.
There are several factors you should consider when selecting the right pair of lead glasses. First of all, you should look at the lead equivalency of the radiation glasses’ lens . The medical industry standards for lead equivalency of lead glasses are .75 mm. You should make sure that the radiation glasses meet the industry standards or exceed them to insure adequate protection from radiation exposure. If you are looking for glasses that offer the maximum protection, there are models available with side shields to provide additional wrap around protection.
In terms of fit, you should make sure the nose piece of the lead glasses fits comfortably and securely on the nose. The ear piece of the glasses should either wrap around or rest on the ear. To offer the maximum amount of protection from radiation, the frame of the lead glasses should fit closely to the side of your head. This close fit will allow the glasses to stay on during medical procedures.
And remember, it is better to be safe than sorry. Always wear your lead glasses when working around radiation.
