Free colored contact lenses are frequently available through sample programs offered by contact lens manufacturers. It is also possible to receive a free pair of colored contact lenses as a promotion offered by optometrists' offices, and as part of deals such as "buy one get on free" sales.
Many contact lens companies offer free samples of colored contact lenses on their websites. These companies usually require that the customer has a valid prescription from an optometrist to receive the sample, but some may offer samples of lenses without requiring a prescription. Optometrists' offices also frequently give out samples of contact lenses, including the colored variety. Many stores that sell contact lenses offer promotions in which a customer can receive a free pair of contacts after purchasing a pair.
