Many of us spend most of our day in front of screens—at work, at home, and even before bed. Our eyes are constantly working to focus, and even minor vision issues can lead to fatigue, headaches, and reduced concentration. But when is it time to get your eyes checked? And how can you protect your vision in a world dominated by digital devices?

How Screen Time Affects Your Eyes

When you work at a computer, your eyes focus at a fixed distance for long periods. The tiny muscles that control your eye’s lens are under continuous strain, and you blink less often—sometimes only half as much as usual. This can cause dryness, irritation, and a feeling of tired eyes by the end of the day.

Common symptoms of digital eye strain include:

• Blurry vision, especially later in the day
• Headaches or pressure behind the eyes
• Difficulty refocusing between screen and paper
• Dryness, burning, or redness in the eyes

If you notice any of these signs, it may be time for an eye exam.

How Often Should You Get an Eye Exam?

In the United States, the American Optometric Association (AOA) recommends that adults have a comprehensive eye exam at least every two years. However, if you spend many hours in front of a screen, wear glasses or contact lenses, or notice changes in your vision, you should schedule an exam once a year.

Certain groups should be especially attentive:

• Adults over 40: Vision changes more rapidly, and the risk of age-related eye diseases such as glaucoma and cataracts increases.
• Children and teens: Regular eye exams are important for learning and development, as vision problems can affect reading and concentration.
• People with diabetes: Should have a dilated eye exam at least once a year, since diabetes can damage the retina.

A typical eye exam takes about 20–30 minutes and can detect not only vision changes but also early signs of eye disease.

Workplace Vision and Computer Glasses

If you work extensively at a computer, your employer may offer vision benefits through insurance or a workplace wellness program. Some companies even provide coverage for computer or “blue light” glasses designed to reduce eye strain.

Computer glasses are optimized for the distance between your eyes and your screen—usually 20–28 inches. They can make a big difference in comfort and productivity, especially if you experience fatigue or headaches during the workday.

Healthy Habits for Your Eyes

While regular eye exams are essential, you can also take simple steps to reduce eye strain in your daily routine.

• Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds. It gives your eyes a much-needed break.
• Adjust your lighting: Avoid glare on your screen and use soft, indirect light.
• Position your screen correctly: The top of your monitor should be at or slightly below eye level.
• Blink consciously: It helps keep your eyes moist and comfortable.
• Stay hydrated and use artificial tears if needed: Especially in air-conditioned or heated environments.

Small adjustments to your workspace and habits can make a big difference in how your eyes feel throughout the day.

Don’t Ignore Changes in Your Vision

Vision changes often happen gradually. You might find yourself squinting, moving your screen closer, or taking more breaks without realizing why. Even subtle changes can signal that your vision has shifted—and that it’s time for an exam.

Getting your eyes checked isn’t just about updating your prescription; it’s about maintaining lifelong eye health. Your eyes are delicate, and early detection of problems can prevent permanent damage.
