Digital devices such as smartphones, tablets, and computers have become an integral part of our daily lives. They’re used in every part of life, from work to communication, to entertainment, and even education. While these devices have made our lives easier, there is also a growing concern about the impact of screen time on our health.
One particular area of concern is the effect of digital screens on the development of myopia, also known as nearsightedness. Myopia is a condition where far away objects appear blurry while nearby objects can still be seen clearly. Myopia has become increasingly common in recent years, especially among children and young adults.
Recent research suggests that prolonged screen time may contribute to the development and progression of myopia. Moreover, extended close-up focus can cause eye strain and fatigue.
Understanding Myopia
Myopia occurs when the eyeball grows too long or the cornea is too curved. This causes light to focus incorrectly on the back of the eye, resulting in blurred vision for distant objects. While myopia can be corrected with glasses, contact lenses, or surgery, severe or high myopia can also lead to other eye problems such as glaucoma and cataracts if left untreated.
The prevalence of myopia has been steadily increasing worldwide, with some countries reporting rates as high as 80-90% among young adults. A study conducted in California found that 41.9% of those under the age of 19 had myopia. This trend is concerning as myopia can have a significant impact on one’s quality of life and overall health.
The Connection between Screen Time & Myopia
Research has shown a strong correlation between screen time and the development of myopia. This is mainly due to two factors—increased near-work activities and reduced outdoor time.
With the rise of digital devices, children and adults are spending more time engaged in near-work activities such as reading, writing, or playing video games on screens. These activities require sustained focus at a close distance, which can strain the eyes and lead to myopia.
At the same time, there has been a decrease in outdoor activities among children and young adults. Outdoor time allows for exposure to natural light, which plays a crucial role in regulating eye growth.
When spending time outdoors, the eyes are exposed to brighter light, which triggers the release of dopamine, a neurotransmitter that inhibits eye growth. This helps keep the eyeball from growing too long and becoming myopic.
Other Factors to Consider
Apart from screen time and outdoor activities, there are other factors that may contribute to the development of myopia. These include:
- Family history: If one or both parents have myopia, the child is at a higher risk of developing it.
- Education: Higher levels of education have been linked to an increased risk of myopia. This is thought to be due to the intense near-work activities involved in studying.
It’s important to consider these factors and take necessary precautions if you or your child are at a higher risk for myopia. Regular eye exams and following the tips mentioned above can help prevent or slow down the development of myopia.
Preventing Myopia
While genetics do play a role in the development of myopia, research has shown that lifestyle factors can also significantly impact its progression. Limiting screen time and increasing outdoor time have been found to be effective ways to prevent or slow down the development of myopia.
Parents can encourage their children to take regular breaks from screens and engage in outdoor activities such as sports or simply spending time outside. Implementing good habits such as holding devices at an appropriate distance and maintaining good posture while using screens can also help reduce the strain on the eyes.
Professional Treatment for Myopia
If you or your child are diagnosed with myopia, there are various treatment options available:
- Prescription glasses or contact lenses: These can help correct the refractive error and improve vision.
- Orthokeratology: This involves using special contact lenses overnight to reshape the cornea and temporarily correct myopia.
- Refractive surgery: In severe cases of myopia, surgery may be recommended to permanently correct vision. However, this should only be considered after consulting with an eye specialist.
Additionally, while myopia cannot be reversed, myopia control strategies have been shown to slow the development of myopia in children, resulting in better vision in adulthood.
It’s important to seek professional treatment and regularly monitor any changes in your or your child’s vision if diagnosed with myopia. Ignoring or delaying treatment can lead to complications and further deterioration of eyesight.
