Contact Lenses Effects:
•Hard lenses apply gentle pressure on the cornea and reduce the curvature.
•Hard contact lenses also temporarily compress the eyeball thereby reducing its length.
•The effects may last for several days.
•When contact lenses wear is discontinued, the eye gradually returns to its previous shape.
•These contact lenses are not suitable for long-sightedness or Hypermetropia.
•Overnight contact lenses are custom made depending on the curvature and measurements of the eye for even pressure and accurate correction.
•These measurements are determined by a procedure known as topographic mapping.
•The patient’s prescription power is also incorporated in the contact lenses.
•Studies have shown that these contact lenses can correct upto 70% of the refractive error in the first night and 100% in a week
•These contact lenses yield best results in refractive errors of -5.00 or less.
•In future these contact lenses may help in completely treating myopia in growing children.
