Custom Contact Lenses Redefine Optimal Eyesight
Contact lens manufacturers are on the verge of offering custom-made contact lenses
that hold the potential to provide superior vision by correcting for tiny inconsistencies
or “aberrations” in the cornea and retina. Aberrations are detected through the use of
a “wavefront” aberrometer that uses beams of light to draw a topographical map of the front
of the eye. That map then is used to form a mold that, in turn, creates a personalized lens.
Contact lenses that correct for aberrations of a general nature exist now, but this new
technology is designed to employ hundreds of points of information to individualize each
contact lens to improve contrast sensitivity, reduce glare and maximize overall acuity.
Aberration-control lenses may well deliver a level of clarity that redefines what we think
of as crisp vision.
