Tool novelty contact lenses give your eyes a dramatic, technical appearance that draws attention in a subtle yet striking manner. The futuristic design of the lenses features bright white irises framed with a black outline and four T-shaped images on each corner of each lens. Although this design has a minimalist quality, the lenses are sure to get you noticed whether you wear them for Halloween events, theatrical performances, costume parties, conventions or any ordinary night on the town.
The simple design of Tool contact lenses comes with an equally simple construction, which features two ingredients of polymacon and water. Polymacon makes up 62 percent of the lenses and is an innovative polymer material that quickly conforms to the shape of your eyes. This is made possible by the material's gel-like consistency, which is easily moldable and features a comfortably smooth and silky feeling. The remaining 38 percent of the lenses is made up of water to keep your eyes fully hydrated despite a dry environment or otherwise strenuous conditions.
With an extensive one-year lifespan, you can wear your Tool contact lenses to several special events and everyday occasions to get full use from this awesome accessory. Be sure to wash and store the lenses after each use to maximize comfort and performance throughout this period.
