Power vs. Plano Explained

“Power” and “Plano” Explained

 

Power refers to the strength of vision correction for contact lenses.  Measured in diopters, it is scaled in 0.25 increments and is always preceded by a + (plus) or a – (minus).  If you do not require corrective vision, please select the Plano (0.00) option when purchasing contact lenses.  The FDA now considers all contact lenses medical devices – this includes non-corrective Plano (0.00) lenses – and can only be sold with the involvement of an eye care professional.  Due to new Federal law, it is required that you, the customer, see an eye care professional and obtain a valid prescription before purchasing any corrective or Plano contact lenses.
