The optometrist will likely ask about any eye or vision problems you may be having and about your overall health. The optometrist will also ask about any former eye or health issues of you and your family.
Checking Your Visual Acuity
Reading charts are often used to determine visual acuity. Visual acuity measurements analyze how precisely each eye is seeing. As a component of the testing, you are usually asked to read letters on distance and near reading charts. The outcomes of visual acuity testing are written as a fraction like 20/40.
When assessing distance vision, the top number in the fraction is the common distance at which testing is done, twenty feet. The lower number is the smallest letter size you were able to read. A person with 20/40 visual acuity would have to get within twenty feet of a letter that should be seen at 40 feet to see it properly. Standard distance visual acuity is 20/20.
Preliminary testing may include investigation of specified elements of visual performance and eye health such as depth perception, color vision, eye muscle movements, peripheral or side vision, and the way your pupils react to light.
Keratometry Vision Test
This test computes the curvature of the cornea, the transparent outside area of the eye, by directing a circle of light on the cornea and measuring its reflection. This measurement is extremely significant in figuring out the appropriate fit for contact lenses.
Refraction Vision Test
Ascertaining refractive error with a phoropter and retinoscope. Refraction is performed to establish the applicable lens power needed to compensate for any refractive error (nearsightedness, farsightedness, or astigmatism). Making use of an instrument called a phoropter, your eye doctor places a set of lenses before your eyes and assesses how they focus light utilizing a hand held lighted instrument termed a retinoscope. The optometrist may decide to utilize an automated instrument that automatically analyzes the focusing strength of the eye. The power is then refined by the person's feedback to determine the lenses that provide for the best vision.
This examination may be completed without the use of eye drops to find out in what way the eyes respond under common seeing conditions. Sometimes, for instance for individuals who aren't able to respond verbally or when some of the eyes focusing strength could be concealed, eye drops are used. The drops temporarily keep the eyes from changing focus while the examination is performed.

Any individual with eye pressure greater than 22 mm Hg is at an increased likelihood of developing glaucoma, even though lots of people with standard pressure also develop glaucoma.
