In today's digital world, screens are unavoidable. From online learning to YouTube and gaming, kids today are growing up in front of screens. While technology brings opportunity, it also introduces new challenges, especially for children’s developing eyes. Your child may be silently suffering from strained eyes, headaches, or blurry vision during screen time. But what if the issue isn’t just screen overuse? What if their natural eye structure is working against them, and you don’t even know it yet? Let’s explore why undiagnosed astigmatism may be behind your child’s screen struggles, and how early action (including DNA testing!) can help protect their vision for the future.

What Is Digital Eye Strain? |
Digital eye strain, also known as Computer Vision Syndrome, is a group of eye and vision problems caused by prolonged screen use. Symptoms include:
- Blurred or double vision
- Headaches
- Eye discomfort or fatigue
- Dry eyes
- Neck and shoulder pain
According to the American Optometric Association, up to 90% of people who use digital devices for more than two hours per day experience some form of digital eye strain (American Optometric Association, 2023). Kids are especially vulnerable because their eyes are still developing. Here’s what to watch out for if your child is constantly exposed to screens:
- Rubbing eyes or blinking frequently
- Trouble focusing during screen-based lessons
- Sitting too close to screens or squinting
The Overlooked Link: Astigmatism and Eye Strain |
Many people don't realize that undiagnosed or uncorrected astigmatism can significantly amplify the symptoms of digital eye strain.
What is Astigmatism?
Astigmatism is a common vision condition caused by an irregular curvature of the eye's cornea or lens, which leads to distorted or blurred vision. It's often hereditary and can appear from a young age (Mayo Clinic, 2023).
When someone with astigmatism looks at a screen, their eyes must work harder to focus. This constant effort causes faster fatigue and discomfort.
Even mild, undiagnosed astigmatism can make screen time far more tiring than it should be (Sheppard & Wolffsohn, 2018). And because children rarely realize their vision is off, they assume what they see is normal, thus, these issues can go unnoticed for years.
Why Knowing Astigmatism Risk Early Makes a Difference |
Almost half (48%) of parents admitted that they know less about their children’s eye health than they should. (Palombi & Kwan, 2020). Identifying a child’s or adult’s genetic tendency toward astigmatism can allow earlier interventions such as vision correction and adjustments to screen time before it begins to affect their learning, development, or overall comfort.
This is especially important today, as children are spending more time on digital learning platforms from an early age.
Take a Step Further: Know Your Eye Health from the Genes Up |
Understanding your child’s genetic predisposition to astigmatism is a game-changer. No eye issues are created equal. Some can be managed with a screen break. Others, like astigmatism, require early identification and ongoing support.
At Absolute Genetic Technologies, our DECODE TALENT DNA TEST can uncover your child’s genetic risk for astigmatism, giving you peace of mind or the power to take early action before it impacts their focus, academic progress, and overall wellness. Plus, explore how our DECODE NUTRITION DNA TEST can guide you in optimizing your child’s diet to support healthy eye development.
