Dangers of Blue Light

When you are looking at your computer screen, smartphone, or television, the blue light exposure you receive is relatively small, in short doses. However, long-term exposure to blue light can be detrimental to your eyesight, and may contribute to very serious conditions. If you’re concerned about blue light, here’s what you need to know. In the meantime, consider getting blue light glasses in Modesto, CA.

Children’s Eyes are More Vulnerable

While kids love digital devices, too much of a good thing may be bad for their eyes. Based on a study from the National Eye Institute, children’s eyes absorb far more blue light from computers, cellphones, and televisions than adult eyes. Therefore, it’s important to limit the amount of time children spend each day staring at such devices.

Digital Eyestrain

As you spend more and more time staring at your computer or smartphone, the result could be what’s known as digital eyestrain. Due to the blue light decreasing the contrast of what you are looking at on the screen, your eyes may become much drier and feel fatigued. In addition, you may start to experience headaches and have difficulty focusing. This is another reason why you should consider blue light glasses in Modesto, CA.

Macular Degeneration

In more severe cases of overexposure to blue light, some NEI studies have suggested retinal cells can become damaged, making you more susceptible to age-related macular degeneration. Should you start to notice changes in your vision that you believe might be related to blue light, talk to your eye doctor as soon as possible.

Fixing the Problem

If you feel that you may be experiencing blue light issues, there are ways to decrease your exposure to blue light. For example, you may consider using blue light glasses, or you can opt to try screen filters for your computer or smartphone.

To learn more about blue light and its dangers, discuss your concerns with your Modesto, CA eye doctor during your eye exam.

What Are Eye “Floaters” and Are They Dangerous?

Sometimes, when looking around, you may notice spots or long “wormy” things that seem to be floating within your field of vision. While this can be unsettling, your eye doctor in Modesto wants you to know that floaters are often harmless and pose no significant threat to your vision.

What are Floaters?

When you see a floater, you are seeing portions of the vitreous, the clear gel-like fluid that fills up the inside of your eye. Known to shrink as you age, the vitreous sometimes pulls away from the eye wall, resulting in the small spots you may see now and then. In some cases, floaters can be caused by blood seeping into the vitreous, a common problem if you suffer from diabetic retinopathy.

How Will I Recognize a Floater?

In addition to looking like small spots, floaters can also take on the appearance of threads or cobwebs. Annoying because they move as your eyes move, floaters can usually be easily moved out of your field of vision by moving your eyes around at a somewhat rapid pace.

Are Floaters Dangerous?

The vast majority of the time, floaters are not dangerous. In fact, most floaters disappear within a few weeks or perhaps months. In very rare cases where floaters are visually debilitating or severely restricting your vision, you could undergo a vitrectomy. A mostly painless outpatient surgery, it can give you relief should your problem be severe.

When Can Floaters be Dangerous?

Once you start to notice floaters, you should always have an eye exam so your doctor can check your retina. If an underlying retinal condition is found, such as a detached retina, you will need immediate treatment. Should you ignore floaters that are resulting from a serious eye condition, blindness could be in your future.

Should you be experiencing floaters and want to learn more about them, schedule an eye exam with your eye doctor in Modesto to get answers and peace of mind.
