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.
High degrees of astigmatism are better corrected with eyeglasses or RGP toric contact lenses. Toric contact lenses are more expensive than normal contacts because of the extra correction they provide. Surgical treatments include LASIK Eye Surgery, PRK (photorefractive keratectomy), and astigmatic keratotomy (AK).
