I've been diagnosed as prediabetic. How will this impact my eyes?

Increased blood sugar levels in prediabetes can cause harmful changes in the eye, such as damaged blood vessels in the back of the eye known as retinopathy, very rapid production of cataracts in the eye, and vision loss through vision shifts over time. The back of the eye is the only place in the body where an eye doctor can directly and noninvasively view blood vessels through a comprehensive eye exam. Eye doctors can play a critical role in spotting signs of chronic diseases before they progress and cause irreparable damage, including vision loss. When diagnosed with prediabetes, it is important to get your eyes examined annually, or as frequently as recommended by your eye care provider. Look out for vision changes and tightly monitor your blood sugar with your general practitioner to ensure your best health outcomes.

Why do my eyes always feel tired?

Mobile devices and computers deliver countless benefits. However, they can also have an unpleasant side effect – digital eye strain. Many digital devices and computer monitors emit blue light, and blue light exposure can contribute to digital eye strain. And as digital device use isn’t likely to dwindle any time soon and you’re probably more likely to hand over the keys to your car than your smartphone. Therefore, it’s vital to find other ways to cut back on your blue light intake. Here are three tips for avoiding eye fatigue you may encounter from time in front of a screen.

1. Observe the 20-20-20 rule: Give your eyes a break every 20 minutes and spend 20 seconds looking at something at least 20 feet away. Also, blinking more often helps to moisten your eyes, which may help reduce visual discomfort.

2. Consider lenses that filter blue light: Lenses are available that help reduce exposure to blue light that is emitted from digital devices. This near-clear coating is a great choice if you spend two or more hours a day in front of a screen or under LED or fluorescent lighting.

3. Consider your work environment: Are you sitting under a heater or air conditioning? Consider a desk humidifier to help with moisture in the air. In addition, find a comfortable working distance from your screen.
