What is a 'clear' contact lense prescription?

I'm a filmmaker, and I was thinking of using a pair of these theatrical lenses in an upcoming project: http://www.lensway.co...lloweenLenses-p1.html

One problem: they ask for your prescription. So, what is the prescription for someone with no form of visual impairment?

Plano

What about Plano (non-prescription) Contact Lenses?


Some contact lenses are available in plano (non-prescription). Sometimes, patients without a need for vision correction want to change their eye color by wearing these cosmetic colored or special effects lenses.

While these lenses are termed as either cosmetic, non-prescription or plano, the wearer still needs to have an eye exam and contact lens fitting from an eye care provider because contact lenses are made from different materials, and the diameters and base curves are different sizes. What works for one patient might not work for another.

they come in different diameters(dia) and different base curves (BC). Plano are made for people who do not need a visual prescription -but eye shapes are different and you may not fit the planos.
