An eye examination is various tests that all people should do regularly and periodically. The eye is one of the most important organs of the human body, therefore the eyes should be examined regularly from birth to adulthood. It should be noted that the eye examination is different from the vision test. In addition to vision testing, the ophthalmologist also examines the eye for diseases that do not have early symptoms.
An eye examination includes tests such as the quality of vision testing as well as depth and dimension of vision testing which is performed so as to understand the position of the objects. A thorough examination of a person's refractive error is also important in these examinations.

When should an eye examination be performed? Since the only way to diagnose eye diseases is to have a specialist doctor check your eyes, so it is better to have a regular eye examination.
However, some patients need to be more regular due to the presence of risk factors. Some of the risk factors include:

• Family history of eye diseases
• Being over 5 years’ old
• Diabetes
• A history of eye trauma

Ophthalmologists recommend that every person should undergo a complete ocular examination every 2 to 5 years

What problems does an eye examination identify?

• Refractive errors: Includes farsightedness, myopia, astigmatism
• Amblyopia
• Strabismus The ophthalmologist examines the patient's eye in terms of motor coordination and positioning. Strabismus can impair depth and laziness.
Ocular Diseases: Many ocular diseases, such as glaucoma and early-stage diabetes, have no clear symptoms. An ophthalmologist will look at these diseases in an ophthalmologic examination and begin early treatment if these symptoms are treated. In many cases, early diagnosis and treatment of the disease can reduce the complications and permanent loss of vision.
• Ophthalmic and retinal vein examination: They can show non-eye diseases such as hypertension, diabetes, and high fat.
