Whois & Analysis for acuityeyecaregroup.com

Optometry is a healthcare profession which involves examining the eyes and applicable visual systems for defects or abnormalities as well as the medical diagnosis and management of eye disease.

Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles.

Modern day optometry, however, has evolved through time so that the educational curriculum additionally includes intensive medical training in the diagnosis and management of ocular disease in countries where the profession is established and regulated.

Optometrists (also known as Doctors of Optometry in the US and Canada for those holding the O.D.

degree or Ophthalmic Opticians in the UK) are medical professionals who provide primary eyecare through comprehensive eye examinations to detect and treat various visual abnormalities and eye diseases.

Being a regulated profession, an optometrist's scope of practice may differ depending on the location.

Thus, disorders or diseases detected outside the treatment scope of optometry are referred out to relevant medical professionals for proper care, more commonly to ophthalmologists who are medical doctors that specialize in advanced medical and surgical care of the eye.

Optometrists typically work closely together with other eye care professionals such as ophthalmologists and opticians to deliver quality and efficient eyecare to the general public.

Visual acuity (VA) commonly refers to the clarity of vision.

Visual acuity is dependent on optical and neural factors, i.e., (i) the sharpness of the retinal focus within the eye, (ii) the health and functioning of the retina, and (iii) the sensitivity of the interpretative faculty of the brain.

In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge.

Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle.

This non-ideal focusing may be caused by aberrations of the imaging optics.

In the absence of significant aberrations, the smallest possible blur circle is the Airy disc, which is caused by diffraction from the optical system's aperture.

Aberrations tend to get worse as the aperture diameter increases, while the Airy circle is smallest for large apertures.
