Refractive Error - Too much or too little bending of the light rays entering the eye, so that they focus not on the retina, which would give clear vision, but either in front of it (myopia) or behind it (hyperopia). When the cornea is slightly oval-shaped, rather than perfectly round, it has two curvatures, a steeper one and a flatter one. This also causes refractive error (astigmatism), bending the light rays in two different ways, so that they’re skewed and unable to focus. Refractive error is measured in diopters.

Contact Lens, Daily Wear - Contact lenses designed to be worn only during the daytime.

Contact Lens, Disposable - Contact lenses designed to be worn once and then thrown out, as opposed to the kind that’s removed, cleaned, and reinserted. Depending on the eye doctor’s prescription, disposable contact lenses can be worn for one day, or for up to a week.

Contact Lens, Extended Wear - Contact lenses designed to be worn continuously for up to a week, not being removed for sleep.

Excimer laser is an ultraviolet laser used in refractive surgery to remove corneal tissue.

Farsightedness is the common term for hyperopia.
