A typical application of such a lens is to refocus the correction allowing clear vision at any distance. Unlike with bifocals, near-vision correction is achieved over the entire field of view, in any direction. Switching between distance and near vision is accomplished by re-adjusting the lens, instead of by tilting and/or rotating the head.
G2 licences are kept for 12 months and then he/she can take the G2 exit test, which tests highway driving as well as city driving skills. A G2 licence holder is subject to a new set of restrictions, which are more relaxed than those for the G1 licence: The driver must maintain a BAC of zero, and if the licence holder is 19 years of age or under ...

Orthokeratology lens. Orthokeratology, also referred to as Night lenses, Ortho-K, OK, Overnight Vision Correction, Corneal Refractive Therapy (CRT), Accelerated Orthokeretology, Cornea Corrective Contacts, Eccentricity Zero Molding, and Gentle Vision Shaping System (GVSS), is the use of gas-permeable contact lenses that temporarily reshape the cornea to reduce refractive errors such as myopia ...
A driver's license, driving licence, or driving permit is a legal authorization, or the official document confirming such an authorization, for a specific individual to operate one or more types of motorized vehicles—such as motorcycles, cars, trucks, or buses—on a public road.
Astigmatism may be corrected with eyeglasses, contact lenses, or refractive surgery. [1] Glasses are the simplest and safest, although contact lenses can provide a wider field of vision . Refractive surgery can eliminate the need to wear corrective lenses altogether by permanently changing the shape of the eye but, like all elective surgery ...

After holding the temporary driving licence for at least 1 year, the licence holder may apply for a full 5-year driving licence for the same type of vehicle (2-year car => 5-year car or 2-year motorcycle to 5-year motorcycle).
Subjective Refraction is a technique to determine the combination of lenses that will provide the best corrected visual acuity (BCVA). [1] It is a clinical examination used by orthoptists , optometrists and ophthalmologists to determine a patient's need for refractive correction, in the form of glasses or contact lenses.
