The test involves looking through a device to read letters or recognize symbols on a wall chart through lenses of differing strength which are contained within the device.

Why Refraction Cannot Be Billed Inclusive

Medical carriers are opposed to including refraction in medical eye exams because they do not consider refraction necessary to keep eyes healthy. Never mind the fact that most pathology is found during visits in which refraction is performed.Medical carriers are also opposed to including refraction in medical eye exams to control costs. If they allowed refractions to be bundled with exam codes, patients would always use their medical insurance for routine eye care instead of their vision insurance. Insurance companies would then have to pay us higher medical reimbursements. With the reimbursement for a medical 92004 code hovering around $120, it’s easy to see why some doctors don’t mind throwing in a free refraction if it means getting paid at a rate much higher than vision plans offer, which typically range from $40 to $80.From a medical carrier’s viewpoint, the practitioner who includes refraction at no charge essentially baits patients in for a routine eye exam and then bills the medical carrier for the costs. Therefore, medical carriers mandate a separate charge for refraction to prevent practitioners from billing medical insurance for a non-covered service. This same principle is behind the mandatory collection of co-pays, which deter patients from abusing health care benefits. Eye care professionals who fail to charge patients for refraction are as guilty as practitioners who routinely waive co-pays to attract higher patient volumes.

What Is A Refractive Eye Exam

Eye Refraction Examination – Complete Uninterrupted Refraction

A refraction or vision test determines whether you need vision correction and the prescription power you need for eyeglasses or contact lenses to see clearly. This test measures how light bends when it enters your eyes.

The cornea and lens work together to refract light to focus on your retina. If something prevents light from focusing correctly, you wont be able to see clearly.

Causes of various refractive errors can include:

  • A too-short or too-long eye
  • A thick or thin lens
  • A change in eye shape
  • Irregular cornea shape

When light focuses in front or behind the retina, you can experience blurry vision with objects close-up or farther away. Your eye doctor may use a machine to measure the amount of light reflected by the retina to determine your refractive score, which helps calculate your prescription.

If your optometrist has detected a refractive error, the next step is determining which individual lenses can help you see using a phoropter. As you look at letters on a wall 20 feet away, your eye doctor will change between lenses of varying strengths to see which provides the sharpest vision. Think of when your optometrist asks: which is better: 1 or 2?

What To Know About Nearsighted Prescriptions

Nearsightedness, or myopia, is a common refractive disorder. If youre nearsighted, you can see objects that are close clearly, but objects that are farther away will look blurry.

With nearsightedness, your eye is usually elongated, with too much distance between the cornea at the front of your eye and the retina at the back of your eye. Nearsightedness can also happen if the cornea of your eye is too curved.

Due to this increased distance, light rays fall in front of your retina instead of on it. This can cause your distance vision to be fuzzy.

The lenses in your eyeglasses will correct the bend in the light and help you see distant objects more clearly.

For a nearsighted prescription, the strength of the lenses will be marked with a minus sign. The more nearsighted you are, the higher the numbers will be.

For instance, a lens prescription of -5.00 is a stronger prescription than -2.00. The strength of the lenses can vary for each eye.

What Is A Comprehensive Eye Exam

A comprehensive eye exam is very different from a routine eye exam because, in addition to checking for refractive eye errors, your eye doctor will also evaluate the overall health of your eyes by screening you for common eye diseases. Exactly what will happen at your comprehensive eye exam can vary between providers, but typically you may be given the following assessments:

– A visual acuity test, as is performed in a routine eye exam.

– A cover test, where one eye is covered so that your eye doctor can evaluate how the eyes work independently of one another.

– A test to check your depth perception.

– An ocular motility test to test the movement of the eyes.

– A slit lamp exam which enables your eye doctor to check the shape of the eyeball and spot any abnormalities.

– Pupil dilation, which enables your eye doctor to look into your eyes to check for the presence of any internal eye diseases.

– Glaucoma testing, which checks the pressure inside your eyes.

Most eye doctors recommend that patients attend a comprehensive eye exam at least once every two years, although if you have a pre-existing eye condition, the frequency with which you are asked to attend could be increased.

Are eyes dilated for refraction?

Who Should Have Tests

Refraction tests should be conducted regularly. People under the age of 60, who are healthy and have no outstanding vision problems, should receive a test every two years. When a child turns 3 years old, they should have a refraction test every year or every other year.

A person who wears corrective lenses should take a vision test every one to two years. Eyes change, and regular testing helps a doctor learn if a new prescription is necessary instead of a patient using corrective lenses that no longer offer adequate vision improvement. A patient who has vision problems between their tests should schedule another test rather than waiting for the next planned test.

What About The Numbers

Many of the abbreviations on your prescription will be followed by numbers.

If the numbers are marked with a plus sign or no sign, youre farsighted. If the numbers are marked with a minus sign , youre nearsighted.

Some of the numbers in your prescription tell the eyeglass manufacturer how much correction your vision needs. Eyeglass strength is measured in diopters.

If your prescription reads -1.00, that means your eyeglasses need 1 diopter of strength to correct nearsightedness.

If your prescription reads +2.50, your eyeglasses need 2.5 diopters of strength to correct farsightedness. The higher the number, the more correction your vision needs.

Elderly Patients & Those With Diabetes

A patient who has diabetes should have an eye test every year. Diabetes is associated with a range of eye conditions, such as glaucoma and diabetic retinopathy.

Glaucoma is a condition that occurs when there is too much pressure accumulating in the eye, resulting in damage to the optic nerve and the retina. The American Diabetes Association warns that people who have diabetes have a greater risk for blindness than people in the general population, so regular testing for this group is essential.

People over the age of 60, or who have a family history of glaucoma and other eye conditions, should get a yearly refraction test. Regular exams will alert a doctor to the buildup of pressure in the eye, so they can initiate treatment early.
