Leaded glasses are available in both prescription and non-prescription lenses. Even styles that are marketed or tagged as prescription leaded or lead glasses can usually be ordered with no prescription requirement. The lenses in the non-prescription version of the glasses, like the prescription lenses, are made with a polycarbonate component that is very scuff and scratch resistant, literally providing a lightweight protective coating on the lens itself. If you are ordering with a prescription you simply provide the prescription type at the time you place the order. Prescription lenses come in a range of options. Single vision prescriptions are common but so are bifocals. For those that don't want the line between bifocal areas of the lens a progressive lens is a great option. This is typically an essential consideration for those that wear the glasses constantly.

I have heard that leaded glasses are heavy and uncomfortable to wear, is this a concern? Historically the first use of radiation in medical and research facilities did include some really heavy, clunky and very uncomfortable leaded glasses. Modern technology has done away with all that and now most leaded glasses have frames that are less than 90 grams, so they are always lightweight even if you are constantly working in an area with radiation. New styles that include customizable fit, hydrophilic pads around the nose as well as anti-slip molded frames to ensure comfort even with long wear times. Having a comfortable fit is essential with these important safety types of eyewear. After all if the leaded glasses aren't comfortable technicians, doctors and specialists are much less likely to wear them on a regular basis, leading to increasing risk of eye health conditions due to radiation exposure. What choices do I have in customizing leaded glasses? Besides choosing the specific type of lens prescription there are different options for customizing your leaded glasses depending on your needs. Some styles have side shields for added protection while others are more typically of a standard sunglass or prescription wrap around style of eyewear. Choosing different frame styles and colors is also an option with many different types of glasses. Different colors can be used to keep glasses easy to identify as well as to add that personal touch. Typical color options range from blue, clear, black or brown frames to green, tortoise or silver. Is there any kind of warranty with leaded glasses? High quality leaded glasses typically come with a manufacturer's warranty. This will vary depending on the company that makes the glasses but it is common for the warranty to be two years. This ensures that any damage or malfunction of the glasses will result in a no-cost replacement based on the specific language in the warranty. This warranty does not cover changes in your prescription or eyesight, but it will apply to both prescription and non-prescription lenses.
