Virtual Learning and Eye Health

Since COVID-19 has closed schools and driven students to a virtual setting, screen time and eye health have become an increasing concern. Eye physicians have noticed a significant increase in dry eye syndrome and eye strain from too much screen time. It is safe to say that most computer users experience digital eyestrain. Children are no different than adults. They can experience dry eye, headaches, and blurry vision, too. Usually these symptoms are temporary but, we can expect them to become more frequent if certain precautions aren’t taken. These symptoms don’t necessarily mean there is always a need for computer glasses. It means that more frequent breaks need to be taken looking away from the screen. These symptoms arise simply because we are not blinking as often while we’re using the computer and other digital devices, leaving the eyes dry and irritated. Eye care professionals recommend the 20/20/20 rule. We recommend that patients take a break every 20 minutes by looking somewhere more than 20 feet away for 20 seconds. Here are some tips to help reduce your children’s eye strain from screen use:

• Set a kitchen timer or a smart device timer to remind them.

• Pre-mark books with a paperclip every two chapters to remind your child to look up. On an e-book, use the “bookmark” function for the same effect.

• Use good posture when using a computer.

• Make sure they view laptops at arm’s length, about 18 to 24 inches from where they are sitting. They should have a monitor positioned at eye level, directly in front of the body. Tablets should also be held at arm’s length

• To reduce glare, position the light source behind the back, not behind the computer screen.

• Remember that although anti-glare and blue filter glasses can increase comfort levels in front of the computer screen, frequent breaks are still recommended.

Lastly, eye care professionals urge parents to ensure that children spend more time outdoors. Several studies suggest that spending time outdoors, during early childhood, can slow the progression of nearsightedness. We now live in an electronic day and age. Exposure to digital screens is inevitable so, it’s important to teach our children good habits early.

January is Glaucoma Awareness Month: Protect Your Vision with Early Detection in New Jersey

January 20, 2026

January is Glaucoma Awareness Month, a time to raise awareness about one of the leading causes of irreversible vision loss in the United States. Often called the “silent thief of sight,” glaucoma can develop without noticeable symptoms in its early stages, making regular eye exams in New Jersey essential for protecting long-term vision health. More than four million Americans are currently living with glaucoma, and many do not realize they have it. The condition damages the optic nerve, typically due to increased eye pressure, and often begins by affecting peripheral vision. Without early detection and treatment, this vision loss can become permanent. Who Is at Risk for Glaucoma? While anyone can develop glaucoma, certain factors can increase your risk, including: Being over the age of 60 Having a family history of glaucoma Belonging to certain ethnic backgrounds Living with diabetes or high eye pressure Understanding your personal risk and scheduling routine glaucoma screenings in New Jersey can make a meaningful difference in preserving your sight. The Importance of Comprehensive Eye Exams The most effective way to detect glaucoma early is through a comprehensive dilated eye exam.
