1. Eye muscle test:This test examines the muscles that control eye movement, looking for weakness or poor control.2. Visual acuity test:This test measures how clearly you can see from a distance. 3. Refraction assessment:Refraction refers to how light waves are bent as they pass through your cornea and lens. 4. Visual field test (perimetry):Your visual field is the broad expanse of vision that you can see without moving your eyes.5. Color vision testing:You could have poor color vision and not even realize it. 6. Slit-lamp examination:A slit lamp is a microscope that enlarges and illuminates the front of your eye with an intense line of light.7. Retinal examination:A retinal examination - sometimes called ophthalmoscopy or funduscopy - examines the back of your eye, including your retina, optic disk and the underlying layer of blood vessels that nourish the retina (choroid). Usually before your doctor can see these structures, your pupils must be dilated with special eyedrops. 8. Glaucoma test:A glaucoma test (tonometry) measures your intraocular pressure - the pressure inside your eyes.

1. Refractive error. This refers to nearsightedness, farsightedness and astigmatism.
2. Amblyopia. This occurs when the eyes are turned or when one eye has a much different prescription than the other.
3. Strabismus. Strabismus is defined as crossed or turned eyes. The examiner will check your eyes' alignment to be sure that they are working together.
4. Eye teaming problems. Even if you eyes appear to be properly aligned, it's possible they do not work together efficiently as a team.
5. Focusing problems. These problems can range from incompletely developed focusing skills in children to normal age-related declines in focusing ability (presbyopia) among older adults. 6. Eye diseases. Many eye diseases, such as glaucoma and diabetic retinopathy, have no symptoms in their early stages.Other diseases. Eye doctors can detect early signs of some conditions and diseases by looking at your eye's blood vessels, retina and so forth.

First, your doctor asks about your medical history and any vision problems you might be experiencing. Next, your eye doctor checks your eyes using a light to ensure the exterior parts of your eyes are healthy. Finally, your doctor measures your visual acuity, assesses your need for corrective lenses and examines your eyes for signs of disease.
