Can Phones Cause Blurry Vision? Exploring The Connection


In this fast-growing world, the introduction of several digital technologies has made jobs easier for people. Yet it also comes with drawbacks. A mobile phone is such a gadget or tool that seems impossible to live without due to what it offers and what it could be used for. It’s a common problem that excessive use or the screen time of mobile phones causes damage to the eyes. Let’s take a brief look at the issue symptoms and the necessary information that helps you to stay safe. 

Digital Eye strain

After additional hours of screen time, the eyes ache which signals it had enough. Digital eye strain is caused when a person uses devices with screen light like computers or smartphones for an extended period of time.

Blue light exposure

Devices these days emit blue light with their screen which is a beam of light that shines into your eyes. These blue lights can disrupt sleep or cause fatigue to the eyes leading to blurry vision or damaged eyes.

Phones Cause Blurry Vision

Difficulty in focusing

Staring at a screen for too long causes discomfort or difficulty in focusing. The muscles that help to focus are strained due to the screen time. This is another cause of blurry vision due to the usage of phones.

Reduces Blinking

Using a phone needs focus and attention hence excess usage reduces blinking which leads to dry eyes and lack of hydration causing discomfort and problems in vision.

Pre-existing eye conditions

If you already have an eye condition or issue, spending too much time on your phone doubles the damage. Underlying eye conditions such as nearsightedness, and astigmatism are more vulnerable to invite more problems.

Eye Fatigue and Muscle tension

Another disadvantage of using the phone for additional hours is the weakening of eye muscles. The tension builds up leading to blurred and tired eyes.

Improper viewing distance

Another reason behind eye issues or blurry vision after using phones is poor placement. Holding them too far or too close causes strain on the eyes

Unfavorable lighting conditions

Using your phones in dark environments or excess brightness damages the eye in the long run. Make sure to use phones under adequate lighting conditions and a properly bright environment to prevent this issue.

Lack of breaks

Despite being careful with the threats sometimes taking a break could help your eyes to rest and comfort itself. Not giving it a break from the screen or giving it rest is sure to cause long-term damage.

Temporary effects

Understand that the blurry vision caused due to intense screentime is only a temporary issue and nothing to be feared but considering the causes, taking the right care and approach is substantial to avoid long-term damage, Use the 20-20-20 rule which states to look at something 20 feet away for 20 minutes approximately 20 seconds. This is only one among the few healthy ey exercises or practices that improve vision and tackle these symptoms.

A few other signs include the irritation of eyes due to lack of blinking and it also affects children’s vision who are likely to spend more time on digital gadgets, computers, and phones and have extended periods of screen time. To focus on something on the phone a person often squints or strains which also adds to the issue all these are meant to be taken into account and be treated or necessary precautions for a bright and healthy vision.
