In glasses with powers beyond ±4.00D, the vertex distance can affect the effective power of the glasses. [4] A shorter vertex distance can expand the field of view, but if the vertex distance is too small, the eyelashes will come into contact with the back of the lens, smudging the lens and causing annoyance for the wearer.
A corrective lens is a lens worn in front of the eye, mainly used to treat myopia, hyperopia, astigmatism, and presbyopia. The goal is to bring vision up to 20/20 vision or as close to this as possible. Glasses or "spectacles" are corrective lenses worn on the face a short distance in front of the eye.
The individual would experience difficulty in near vision, often relieved by reading glasses, bifocal, or progressive lenses. [14] Astigmatism is when the refractive power of the eye is not uniform across the surface of the cornea because of asymmetry.

In order to determine if the patient has astigmatism at a particular meridian, the -0.50 JCC is presented at the following axes: 90°, 180° and then check the oblique axes at 35° and 145°. [ 6 ] As the JCC is a combination of two cylindrical lenses, any cylindrical power that is added must be accompanied by a spherical lens equivalent, to ...
