What to Expect From Your Eye Doctor?
An eye doctor is an individual who gives a service related to vision or the eyes. It is basically any health care worker engaged in eye health care, from a practitioner with only a small set of post-graduate training to practitioners having a doctoral degree of vision care. The eye doctor's main duty is to prescribe corrective eyeglasses or contact lenses for individuals who have eye problems or cannot see properly. He also gives educational lectures to his patients on the vision condition and how to solve it. These lectures help the eye doctor to diagnose the problems and suggest the best possible solutions for the same. To understand more about this service just view the link.
Eye exams are conducted to check for various eye conditions like glaucoma, cataract and macular degeneration. These eye exams are usually not conducted for diagnostic purposes but only to get an idea about the patient's eye health. Eye exams may include tests like refraction, visual field tests, ocular nerve tests, several blood test, corneal topography, optical coherence tomography (OCT) and visual examination. The patient undergoing an eye exam is required to answer several questions relating to their knowledge of vision care, their reaction to light, their response to sound and their preferences in cosmetic and practical procedures. The exam is usually conducted by the optometrist, and it is conducted in a qualified office equipped with proper lighting, comfortable seating, and equipment for detecting eye irregularities.
Refraction Assessment: This test is conducted to check for problems related to the condition of the patient's vision, and is also called refraction assessment. A refractive examination is done by examining the patient's near and far field vision with the use of a refraction assessment device which contains wheels. There are various types of refraction assessors like the automated refraction assessor, the digital refraction assessor, the optical refraction assessor, and the multifocal lens testing assessor. The latter two types of refraction instruments have different lenses and contain wheels fitted in them. The near and far lenses of these two different lenses contain different prescriptions, and when the wheels on the refraction analyser move, they move on a disc which contains different lenses.

Visual field examination: This is a special eye exam that is usually carried out during routine eye checkups. It can be done either in the eye itself or in a scoped surgical scope or a specialised eye hospital room. During the visual field examination, a trained medical practitioner will examine the patient's eyes under a magnifying instrument or eyeglass. They will take note of any irregularities in the patient's vision and any abnormalities on the surface of the eyeball. This exam can help in determining whether the patient requires any corrective eyewear or not.
Color Vision: This includes measurement of the color vision of the person. The eye doctor will use a color vision test called a color vision screening to check whether the patient is able to see color details of objects in dim light, or details of color shades on objects in more intense light. If color vision is tested properly, the doctor will be able to determine with great accuracy whether a person has any particular deficiencies in his/her eyesight. The evaluation also reveals whether a person has monochromatic (x/y) vision or bifocals (x, y, and green). Monochromatic vision allows a person to see all colors of light, including yellow, red, and blue; bifocals allow a person to see all colors of light that are produced by the human eye, including green, blue, and red; and the rest is grey. A comprehensive color vision test will let the doctor know about any eye problems other than those mentioned above.

A color vision examination can be done either individually or in a group. In a group, one eye doctor may diagnose and treat a color vision deficiency while the others try to treat the same condition independently. In some cases, the eye doctor may treat a color deficiency first and then refer the patient to another eye doctor to treat another eye problem. This is known as "sub-optimal" treatment. Either way, the patient must follow the doctor's orders for proper correction of the problem.
