Comprehensive Eye Exams

eye exam in houstonA Regular Eye Examination is the Secret to Healthy Eyes

Regardless of your age or physical health, it’s important to have regular eye exams at Northside Family Eye Care in Houston. It is crucial that all of us have an eye check up routinely. A routine eye check is even more crucial for kids. Children need to have a vision test from as young as 6 months. At 3 and 6 their eyes need to be examined once again. Routine eye examinations are especially important when your child begins high school. If you think your son or daughter may have an eye issue, do not hesitate – get an eye evaluation done as swiftly as possible.

Early infants often get vision issues as they grow, so their eyes needs to be examined more than a child with standard sight. Children with a family history of eye disorders are also at risk of hereditary vision issues, and they too have to have more regular eye exams.

In men and women, the frequency of eye tests will differ according to age. Men and women older than 40 years, who have standard sight, need to have an eye test every 2 or 3 years. However, those who already wears glasses or contacts needs an eye examination every year.

People with high blood pressure or diabetes should arrange a optical evaluation every year. Adults over 40 need to have their eyes assessed every two years, while those over 60 years of age should go once a year for an eye examination. People older than 60 years can be prone to presbyopia, macular degeneration and cataracts.

Just like other organs of your body, your eyes should be looked after thoroughly by an eye doctor. To maintain healthy eyes, you need to consume a lot of fresh fruit and vegetables. Take vitamin and mineral supplements. If your eyes are starved of Vitamin A, you might get night loss of sight. When going outdoors in bright sunlight, use sunglasses that have high UV defense.

What happens during an eye exam?

Periodic eye and vision exams are a fundamental part of preventive health maintenance. Many different eye and vision conditions have no noticeable indicators or symptoms. As a result, individuals are often blind that problems are present. Early diagnosis and treatment of eye and vision concerns are crucial for sustaining excellent vision and eye health, and when attainable, helping prevent vision loss. As part of our full eye care services, a comprehensive adult eye and vision examination might include, but is not restricted to, the following tests.

Patient History

A patient history really helps to establish all symptoms the individual is experiencing, at what time they began, the presence of any kind of fundamental heath conditions, prescription medications being taken and occupational or environmental conditions that may be affecting vision. The doctor 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 from you and your family.

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 evaluating 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 Tests

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.


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.


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.

Eye Focusing, Eye Teaming, and Eye Movement Testing

Assessment of accommodation, ocular motility and binocular vision establishes how effectively the eyes focus, move and work together. So as to obtain a distinct, singular image of what is being viewed, the eyes must correctly change focus, move and work in unison. This evaluation will search for issues that prevent your eyes from focusing proficiently or make using both eyes together challenging.

Eye Health Evaluation

Tonometry evaluates eye pressure. Elevated pressure in the eye signifies a heightened chance for glaucoma.

Exterior examination of the eye includes evaluation of the cornea, eyelids, conjunctiva and bordering eye tissue utilizing intense light and magnification.

Appraisal of the lens, retina and posterior part of the eye could be carried out by using a dilated pupil to provide a better picture of the internal structures of the eye.

Assessment of pressure within the eye (tonometry) is completed. Standard eye pressures range from 10 to 21 millimeters of mercury (mm Hg), averaging about 14 to 16 mm Hg. 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.

Additional Testing

Additional testing might be called for based upon the outcomes of the other tests to prove or eliminate possible issues, to resolve ambiguous findings, or to supply a more thorough analysis.

Eye care experts recommend you have a complete eye exam every year to assess yourHelp your child choose eyewear risk for potentially damaging eye conditions, as well as to keep on top of any changes in vision you may be experiencing.

If you are over 40, it’s a good idea to have your eyes examined every one to two years to check for common age-related eye problems such as presbyopia, cataracts and macular degeneration. Read more about Vision After 40.

Because the risk of eye disease continues to increase with advancing age, everyone over the age of 60 should be examined annually. Read more about Vision After 60.

Children’s Eye Exams

Some experts estimate that approximately 5% to 10% of pre-schoolers and 25% of school-aged children have vision problems. According to the American Optometric Association (AOA), all children should have their eyes examined at 6 months of age, at age 3 and again at the start of school. Children without vision problems or risk factors for eye or vision problems should then continue to have their eyes examined at every year throughout school.

Children with existing vision problems or risk factors should have their eyes examined more frequently. Common risk factors for vision problems include:

  • premature birth
  • developmental delays
  • turned or crossed eyes
  • family history of eye disease
  • history of eye injury
  • other physical illness or disease

The AOA recommends that children who wear eyeglasses or contact lenses should have their eyes examined at least every 12 months or according to their eye doctor’s instructions. Read more about Pediatric Eye Exams.

Final Summary and Evaluation of your eye exam

At the completion of the exam, your eye doctor will assess and evaluate the final results of the testing to establish a diagnosis and make a treatment plan.

In some cases, recommendation for consultation with, or treatment by, another optometrist or other health care professional might be indicated.
