The most common black contact lenses available are:

1. Opaque black contacts:

   • These are solid black lenses that completely cover the natural eye color, creating a bold and dramatic black eye appearance.
   • Opaque black contacts are often used for special effects, cosplay, or to achieve a unique aesthetic look.

2. Tinted black contacts:

   • These lenses have a light tint of black that partially obscures the natural eye color, creating a darker or smoky eye appearance.
   • Tinted black contacts may appear more natural than opaque black lenses, black colored contact lenses  as they allow some of the natural eye color to show through.

Apart from these two main options, there are no significantly different shades or hues of black available in contact lenses. The color black is typically used in its pure, solid form or as a light tint to modify the eye's appearance.
