Is Screen time affecting your eyesight? 

Harrold Opticians • June 7, 2019

The reliance on electronic devices such as computers and mobile devices for work and social purposes is getting more and more prominent. Everyone’s heard the myths your grandparents use to tell you about your television making your eyes go square – but what effects does too much screen time actually have on your eyesight?

Spending too much time on your devices can result in your eyes becoming sore, heavy and tired, and can later be accompanied by headaches and nausea. ‘Dry eyes’ is also a common symptom of screen over-use, which could potentially become more serious later down the line if it’s not treated correctly. Finally, too much screen time can also cause myopia, which is a near-sighted condition where you can see objects near to you clearly – but far away objects are blurry.

So you now know the symptoms, here’s how to prevent them happening:

1. Follow the 20-20-20 Rule

Always remember to give your eyes a break. This can be done by following the 20-20-20 rule by ensuring you look away from your screen every 20 minutes, at an object 20 feet away for approximately 20 seconds. This can help to reduce the day-to-day strain on your eyes. Blinking regularly is also a good way to keep moisture in your eyes, preventing you from developing dry eyes.

2. Change the Lighting & Rearrange Your Desk

You may not know this, but the lighting in the room that your computer or device is located in can improve or worsen screen-time symptoms. Changing the lighting around you can reduce the effects of your computer screen. Try to ensure that there is no window glare reflecting on your screen, this can be done by moving your desk to a more shaded part of the office/room. We also recommend purchasing a moveable shade lamp to assist in casting an even light over your desk.

Positioning your computer and rearranging your desk is also a good way to prevent negative symptoms in your eyes. Make sure that your screen is positioned slightly below eye level, approximately 20 inches away from your eyes.

3. Change your screen setting

It is easy to assume that you have to use the factory computer settings on your computer, phone or tablet – but you can change these to suit! Adjust the brightness, contrast and font until you find the setting which is healthiest for your eyes.

If you are experiencing any of the symptoms mentioned or currently struggling with your eyesight, then we recommend that you visit an expert as soon as possible.

High blood pressure, or hypertension, affects millions of individuals worldwide and is a significant risk factor for various health complications. Among these complications, one lesser-known but critical aspect is its impact on eye health. Here we have connections between high blood pressure and eye disease, focusing on causes, symptoms, diagnostic methods, and treatment approaches for hypertensive retinopathy. High blood pressure occurs when the force of blood against the artery walls is consistently too high. Various factors contribute to hypertension, including excess weight, high salt intake, genetic predisposition, stress, and lifestyle habits like drinking alcohol and smoking. Over time, uncontrolled hypertension can damage blood vessels throughout the body, including those in the eyes. Hypertensive retinopathy, the eye disease associated with high blood pressure, often progresses without noticeable symptoms in its early stages. However, as the condition advances, individuals may experience symptoms such as: Blurred or dim vision Vision loss Double vision Headaches Sudden vision changes, indicating a medical emergency. Examinations: Diagnosing hypertensive retinopathy involves a comprehensive eye examination performed by an eye care professional. Key diagnostic methods include: Ophthalmoscopy: Using an ophthalmoscope, the eye doctor examines the retina to assess the condition of the blood vessels. Narrowing of blood vessels and signs of fluid leakage may indicate retinal damage due to hypertension. Optical Coherence Tomography ( OCT ): This imaging technique provides detailed cross-sectional images of the retina, allowing for the detection of abnormalities such as retinal swelling (edema) or thickening. Fundus Photography: High-resolution images of the retina are captured to document changes in retinal structure and blood vessel appearance over time. Treatments: The primary goal of treating hypertensive retinopathy is to control high blood pressure to prevent further damage to the retina and preserve vision. Treatment strategies may include: Lifestyle Modifications: Adopting a healthy lifestyle can help lower blood pressure and reduce the risk of eye complications. Recommendations include maintaining a balanced diet low in sodium, engaging in regular exercise, managing stress through relaxation techniques, quitting smoking, and limiting alcohol intake. Medication: When lifestyle changes alone are insufficient to control blood pressure, healthcare providers may prescribe antihypertensive medications. These medications work to lower blood pressure levels and reduce the risk of complications associated with hypertension, including hypertensive retinopathy. Regular Monitoring: Individuals with hypertension and hypertensive retinopathy require regular monitoring of their blood pressure and eye health. Routine eye examinations allow for early detection of retinal changes and adjustment of treatment strategies as needed. High blood pressure poses a significant threat to eye health, leading to complications such as hypertensive retinopathy. Understanding the causes, symptoms, diagnostic methods, and treatment options for this condition is crucial for individuals with hypertension.  By effectively managing blood pressure and seeking timely eye care, individuals can reduce the risk of vision loss and preserve ocular health in the presence of hypertension.

Regular communication with healthcare providers and adherence to treatment recommendations play pivotal roles in safeguarding both overall health and vision.
