As winter sets in, many of us spend more time indoors with screens and artificial lighting. 💻

This shift can strain your eyes, but there are simple ways to protect your vision.

Try the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.

Adjust your screen brightness to match your surroundings and consider blue light filters.

Proper room lighting, like ambient light behind your screen, can also reduce strain.

If you’re experiencing eye discomfort, headaches, or changes in your vision, we're here to help!

Think sunglasses are just a summer thing? Think again! ❄️

Snow turns up the glare like a nature-made disco ball, and those UV rays are working overtime in winter. Without proper protection, you could end up with snow blindness or long-term eye damage.

Keep your eyes happy this winter. Come visit us in San Mason City, IA for an eye exam and help finding your perfect winter sunnies.

Diabetes can impact your eye health in ways you may not notice initially. 👁️

Diabetic retinopathy, macular edema, and other diabetes-related eye conditions often develop without symptoms in their early stages. That's why routine screenings with your eye care professional are so valuable. They can catch changes before they impact your daily life.

If you or a loved one has diabetes, book your comprehensive eye exam today.
