I searched for the smart glasses that "restore sight to the blind" in my son's name.

Here’s the translation of your text into English:

As with many four-year-olds, my son has a great fascination with cars. Even though I'm not particularly interested in the subject, he can already identify makes and models of cars from a distance with surprising accuracy, fueled by his growing collection of Matchbox and Hot Wheels. However, we have had to explain to him that we still don't know if he will be able to drive one someday. The brain tumor he was born with left him with vision problems, especially in one eye, and with little hope for improvement.

That’s why the offer from a startup at this year's CES, which promised prototype smart glasses capable of giving "sight to blind people," surprised me. I decided to question the validity of this claim and, in doing so, try to rekindle my faith that technological advances can still transform lives, restoring hope for my son's future.

My four-year-old son was born with a rare pituitary brain tumor known as a craniopharyngioma. When he was diagnosed at 10 months, the tumor was pressing on his optic nerves and affecting his pituitary gland. This resulted in a lack of normal hormonal function affecting basic bodily functions and significant vision loss. The situation was devastating for our family as we tried to glimpse the future. Although it wasn't malignant cancer and rarely translated into loss of life, the heartbreaking stories we heard about quality of life kept us awake at night.

When I received the proposal from Soliddd, I thought about my family, especially my mother who suffers from AMD (Age-Related Macular Degeneration) and my son, who has also lost vision due to his tumor. In the bustling Eureka Park at CES, I sought out the small Soliddd booth, where they were showcasing their SolidddVision smart glasses, a technological device aimed at restoring vision in people with visual impairments, including macular degeneration. According to their ambitious CEO, Neal Weinstock, these glasses work like hearing aids for the eyes, promising to "give sight to the blind."

Despite the absence of tumor tissue since his extraordinary surgery in 2023, my son still needs daily hormone replacements and experiences poor vision in one of his eyes. What affects his daily life the most is his impaired vision, especially in childhood activities like playing hide and seek or recognizing an airplane in the sky. However, I continue to find glimmers of hope.

When I tried on the prototype model of the glasses, the experience felt more like wearing a small headset than conventional glasses. The technology behind them has revolutionary potential. The frames have two external cameras that capture the world and two internal cameras calibrated to the movements of the eyes. The image from the external cameras is projected onto a micro-screen over the lenses, but not all at once. Instead, the lenses have a series of screens, all showing the same image. The idea is that the brain can be tricked into reconstructing this series of images into a single high-resolution image.

The process allows the brain to do what it has always done: combine the images from both eyes to form a clear picture. Although I did not achieve perfect vision immediately while using the glasses, I was able to see the images as a single object. This rekindled my optimism.

Soliddd has begun working with patients who have conditions such as AMD and corneal dystrophy, achieving promising results in initial trials. Additionally, the convenience of the glasses is essential, as if they are uncomfortable or unattractive, they are less likely to be integrated into people's daily lives. Advances in the design of wearable devices are crucial for their adoption.

However, it is important to mention that I cannot currently guarantee that Soliddd glasses are the ideal solution for my son's vision problem, as there may be damage to his optic nerves. Furthermore, this first version of the glasses may have limited battery life, designed for restricted home use. Visual deficiencies are common in my family, so it is encouraging to know that options like Soliddd exist.

My mother's struggle with AMD has made it clear that there is no quick cure for the disease, which tends to progress over time. However, Soliddd's technology could offer an alternative solution. The reality is that these kinds of innovations are just a small part of what I saw at CES. From a smart cane for blind individuals to advanced hearing aids with artificial intelligence.

From this experience, I left behind my skepticism and reignited my optimism regarding the developing technologies that can change lives and potentially allow my son to live out his dream of driving a car someday. Today, I have more hope than ever.
