ORAL CONTRACEPTIVES Oral contraceptives have been implicated in contact lens intolerance, increased corneal thickness, corneal steepening, and increased symptoms of dryness. With the exception of dryness there is little evidence that oral conceptives have any significant effect on contact lens wear. Other causes of the problems that might be thought due to oral contraceptives, such as lens design or fit, solution sensitivity, coated lenses, hygiene and other medications, should be explored.
