Dr. Rafael Trespalacios of Tres Vision Group details the dangers of excessive blue light exposure

All blue light reaches the retina, which can affect vision and prematurely age your eyes.

Our love of technology can disrupt our vision, let alone our sleep, thanks to blue light. Dr. Rafael Trespalacios, Ophthalmologist at Tres Vision Group, Suntree, Merritt Island, Melbourne.

Our love of technology can disrupt our vision, let alone our sleep, thanks to blue light.

Blue light, one of several colors in the visible light spectrum, is abundant in sunlight, flat-panel TVs, computers, laptops, tablets, smartphones, compact fluorescent and LED lights.

The body needs blue light, but in moderation, to enhance both memory and alertness, boost mood, improve alertness and reaction time, and regulate circadian rhythms that enable restful sleep. But that may be too good.

Exposure from sources such as laptops and phones is small compared to exposure from the sun, but the proximity of these screens and our reliance on them is cause for concern for experts.

“Because all blue light reaches the retina, it can affect vision and accelerate eye aging,” added Dr. Trespalacios.
Excessive exposure to blue light can cause eye fatigue, dry eyes, and difficulty focusing.

To make matters worse, research suggests that long-term exposure can damage retinal cells, leading to life-changing disorders such as age-related macular degeneration and AMD. AMD is the leading cause of irreversible blindness in the elderly in developed countries, and worldwide he affects more than 200 million people. glove.

There is the additional problem that too much blue light exposure at night can adversely affect sleep cycles, causing insomnia and daytime fatigue. lived in a relatively dark place.

Now the world is lit up late at night. Blue light from artificial lighting suppresses the secretion of melatonin, a hormone that regulates circadian rhythms.

Studies have shown that lack of sleep contributes to the development of depression, diabetes and cardiovascular disease.

To reduce the negative effects of blue light, Dr. Trespalacios recommends spending less time looking at screens and taking frequent “eye rest” periods. Screen filters available for computer screens, tablets and mobile phones can reduce the amount of blue light emitted by these devices.

Yellowish computer glasses help increase contrast. Anti-reflective lenses in reading glasses can also increase contrast and also help block blue light from all sources. Cataract surgery can greatly protect the eye and retina from blue light and all UV rays using a blue-blocking intraocular lens that replaces the original, now cloudy lens of the eye itself.

Patients can now choose blue-blocking intraocular lenses to replace yellow aging lenses during cataract surgery. These yellowish lenses block both ultraviolet and blue-violet wavelengths and resemble a healthy crystalline lens.

Both animal and experimental studies have demonstrated important protective effects of these lenses, especially for patients at high risk of overexposure to blue light.

Until now, exposure to blue light has been largely confined to the daytime when the sun is shining. However, the current technology and cutting-edge lighting we live in has increased our exposure to blue light, putting our eyes at risk around the clock.

You can’t go back to a candlelit world, but you don’t have to rely on blue light.

“We can’t live in the dark, but we can minimize our exposure to blue light,” says Dr. Trespalacios.

Dr. Rafael Trespalacios and his team were able to establish the TRES VISION Group throughout Central Florida, including Melbourne, Suntree and Merritt Island.

Dr. Rafael Trespalacios received his Bachelor of Science in Biology and Microbiology from his local UCF when the idea of ​​an affiliated medical school was just a dream. He then attended the University of South Florida Medical School, where he excelled through his medical and surgical training and became a certified ophthalmologist.

Dr. Tres never lost sight of his vision of bringing a renowned eye care facility to Central Florida. Through hard work and the support of thousands of happy blind patients behind him, he and his team were able to create his T.resolutionIsion Group locations in Central Florida, such as Melbourne, Suntree, and Merritt Island.
