WASHER ONLY. View All. Spiders are similar to top rings or shade risers in that they are used to reinforce and spread the parts of a lamp or fixture that provide shading. Spiders, however, are generally used to fortify either plastic or glass cylinder-style shades. Though somewhat rare on older lamps, these lamp parts are often found on modern, minimalist-styled light fixtures. We currently offer a brass plated steel spider that is designed for 4â diameter shades or cylinders.
A scleral lens is a specialized contact lens used to manage a variety of eye conditions. It is made of plastic that is clear and rigid, yet allows the eye to breathe, keeping it healthy. A scleral lens is slightly larger than most soft contact lenses and is designed to rest on the white (less sensitive) part of the eye called the sclera. That is why itâs called a scleral lens! This unique design makes the lens very comfortable to wear, all day long.
