Vision is useful to people of just about any stage of life. There are times when you may not be sure about just how well your eye health is, which is why it is important to get your eyes checked every now and then. Despite the generalizations that may come to mind, the world of eye care is not simply composed of eye charts. These days, people work with screening technology, which can test a patient’s vision in an effective manner. For those who are looking for more information on how this all works, some necessary details are provided below.

Visual Acuity

Visual acuity exams test the effectiveness of the eyes distinguishing shapes and details. This can be done by either a nurse, an optician, an optometrist, an ophthalmologist, or a technician. While there are many types of visual acuity tests, they are easy to take, have no risks, and require no preparation. These exams are typically taken by children. The earlier that you get screened for vision problems, the less of a chance that such problems will get worse later on. It is better to be safe now than sorry later. These are also useful for times when your vision is changing.

20/20 Vision

You may be familiar with the term “20/20 vision” (especially given the year that we have entered). The fraction represents an ideal visual acuity. Those who have 20/20 vision have visual acuity at 20 feet away from the objects presented in front of them. If your visual acuity is less than 20/20, then they might require contact lenses, glasses, or surgery, depending on the severity of the vision problems. If you suffer from an eye condition, then you would certainly need to get treatment for it. After all, you cannot be too careful when it comes to your own eye health.

What is a Spot Test?

A spot test requires the most recent vision screeners. What sets it apart from eye chart exams is that it utilizes a handheld device. The performance of the patient’s eye is analyzed through the use of infrared light, among other things. The results are compared to what is expected of the patient at their age so that it can be determined whether or not the patient needs to go through further testing.

The spot test can detect such eye conditions as astigmatism, myopia, and refractive errors. If you are crunched for time, then there is no need to worry since the spot test can take place within just a matter of seconds. Since children sometimes cannot sit still, this brief duration is very beneficial.

Spot Test Results

A one-page summary of the results is given to the patient following the spot test. It would let you know whether they need further testing, or whether they need a prescription for glasses or lenses. If the right side of the page has a checked Yes box, then you will need to go through more vision screening. This may need to be done to detect such issues as farsightedness. While spot tests have a high accuracy rate, you should be aware that an eye exam is still recommended even if you get a “no” box but still have vision problems.

Use Vision Screening Technology

Now that you are a bit more educated on vision screening technology, you should have a better idea of what to expect when it comes to these types of eye exams. The results of these tests will let you know what you have to do to prevent future eye problems that you might need to anticipate. Of course, there might be more related topics that you may wonder about as you look into all this a bit more.
