What Are Vision Screening Devices and Why They Matter

Good vision or eyesight is key to almost everything we do on a daily basis which invariably affects or determines our quality of life. Sadly however, many people do not really know they have a vision problem or do not realize how serious the issue is until it begins to affect their daily routines. That is why it is important for people to go for medical exams which cover vision screening from time to time. 

In years gone by, one would have to visit a specialist to be able to have their eyes examined properly. But thankfully these days, there are vision screening devices that can be used by almost anyone with the slightest medical knowledge or training. These tools are designed for early detection of vision problems and are becoming increasingly popular in different medical facilities, schools and health centers. 

In this article, we’ll look at what these devices are, their function and why they come in handy for everyone. 

What Is Vision Screening?

Vision screen is a more sophisticated term for ‘eye test’ and it is a fast and easy way of checking whether a person has vision problem. While this is not a full eye test or examination, it can help to detect the following issues: -

1. Myopia (Nearsightedness)

2. Hyperopia (Farsightedness) 

3. Astigmatism 

4. Eye Misalignment (Strabismus) 

5. Lazy Eye (Amblyopia) 

The purpose of this screening is early detection so that anyone with issues can be referred to a specialist for comprehensive testing and possible treatment. 

What Are Vision Screening Devices?

These are tools that used to identify possible or potential vision problems without necessarily having direct contact with the eye. These tools can be digital or electronic and they are fast in identifying and accurately screening individuals, especially non-verbal people and children who may find it difficult to use traditional testing methods or eye charts. 

Some common examples of these devices include the following: - 

1. Photo screeners – These gadgets use a camera to get images of the eye and study how light is thrown off the retina. This reflection enables to gadget to detect the risk factors for the common eye problems that we stated earlier. 

2. Autorefractors – These gadgets calculate how light changes as it gets into the eye. This helps to estimate refractive errors like farsightedness or nearsightedness. Screening with this device is quick and does not require any reaction or response from the patient. 

3. Screening Apps and Mobile Devices- Thanks to technological advancement of smartphones, some vision screen devices can now be gotten as attachment for mobile devices or apps. These are mostly used in schools or community health outreaches. Click here for more information about community health and why it matters. 

Why Early Detection Matters

A good many issues with eyesight start in childhood and are not usually noticed because children do not know how to describe their experience. These kids may think that whatever issue is plaguing them is normal. For example, a child that has blurry vision since they were born will think it is normal because they do not know what normal eyesight/vision is. 

When these issues are not detected early and treated appropriately, they can lead to the following issues: -

1. Poor performance in school 

2. Setbacks in learning and reading 

3. Developmental and social challenges

4. Behavioral problems

Even in grownups, when vision problems are undiagnosed, it contributes to issues such as eye strain, headaches, poor driving and sometimes falls for older adults. Regular screening, with the help of sophisticated devices, therefore, helps to nip these issues in the bud before they become complicated. 

Benefits of Vision Screening Devices

The following are some of the benefits that these gadgets provide: -

1. They are Non-invasive and Fast – Most of these gadgets give you results in less than a minute and need little or no direct contact with the patient. This is ideal for children and those with special needs. 

2. Requires Minimal Training – These devices can be used by nurses, school staff or other professional with just a little training. 

3. They are Portable and Convenient – Many of these screening devices are mobile or handheld and can be carried to remote places for community health outreaches. This portability makes it convenient for almost any space or situation. 

4. Early Detection of Uncommon Conditions – There are conditions that are not easily spotted because it takes time before their symptoms show and by then it becomes almost too late. Some of these devices can detect them; an example is amblyopia.
