Obedience to reason is the foundation of liberty. Reason banishes slavery of self to materialism, to political correctness, to folly, and to range-of-the-moment consciousness known best by the hedonist.
A number of factors can change this estimate, including: Astigmatism. Contact lenses that correct astigmatism cost more than soft contacts that only correct nearsightedness or farsightedness. Soft contact lenses for astigmatism, called toric contacts, frequently retail for $50 to $70 for a box of six lenses. So if you replace your toric contact lenses every two weeks, your annual lens cost is roughly $500 to $700.
Also, fitting toric contact lenses for astigmatism takes more expertise than fitting regular soft lenses. For these reasons, getting fitted with toric contact lenses typically costs more than a regular contact lens exam and fitting. Also, because they have a more complex design, the cost of replacement toric contact lenses is higher than the cost of regular (spherical) soft contacts. The difference in cost will depend on the lens design, lens material, and the optical retailer you purchase them from.
