Eye fatigue is no longer a minor issue. Dryness, soreness, photophobia, blurred vision, difficulty focusing, and even accompanying headaches and neck-shoulder soreness. Your eyes are not just tired; they are deprived of oxygen. The eyes are among the organs with the highest oxygen consumption. When oxygen supply cannot keep up, ocular cells cannot work efficiently, and metabolic waste cannot be cleared in time. The hyperbaric oxygen chamber, through physical means, forces high-concentration oxygen into the systemic circulatory system. After adequate oxygen reaches the ocular tissues, it improves ocular microcirculation and helps relieve eye fatigue.
What is Eye Fatigue?
Eye fatigue is a general term for a group of visual disturbances, ocular discomfort, and systemic symptoms that appear after eye use. The eyes are among the organs with the highest oxygen consumption per unit weight. The metabolism of the retina is extremely active and very sensitive to oxygen demand. When we use our eyes for close work over long periods, the ciliary muscle remains in a state of sustained contraction and spasm, leading to insufficient local blood and oxygen supply. At the same time, staring at a screen for long periods causes us to unconsciously reduce our blink rate. With fewer blinks, the tear film cannot be evenly distributed over the ocular surface, and the cornea and conjunctiva do not receive adequate moisture and oxygen exchange. Dryness and fatigue thus follow.
The most common symptom of eye fatigue is a sensation of dryness, feeling as if sand is in the eye, or as if a layer of fog is covering the eye that cannot be relieved by forceful blinking. This is due to an unstable tear film and punctate shedding of epithelial cells on the corneal surface due to water and oxygen deficiency. In severe cases, dryness can evolve into a burning or stinging sensation. The second typical symptom is soreness and photophobia. After prolonged eye use, there is a distending pain around the eye sockets, sometimes radiating to the temples and the back of the head. The eyes become abnormally sensitive to light, finding sunlight glaring during the day and headlights blinding at night. This is due to persistent ciliary muscle spasm and the fatigue of retinal photoreceptors after being overexcited.
The third symptom is blurred vision and difficulty focusing. Small text on a phone must be brought very close. Switching focus from far to near or near to far takes several seconds of adjustment time. This is not a worsening of myopia, but a decline in the eye’s accommodative function. More severely affected patients may also experience headaches, nausea, neck discomfort, difficulty concentrating, and even emotional irritability. The appearance of these systemic symptoms indicates that eye fatigue is no longer just an eye problem but has affected the working state of the entire nervous system.
There are various methods on the market for addressing eye fatigue. The most basic is rest: for every forty minutes of eye use, look into the distance for five minutes; ensure adequate sleep; use warm compresses to promote local blood circulation; use artificial tears to relieve dryness. These methods can provide some relief, but most remain at the surface level and struggle to reach the root of eye fatigue: the ischemic ciliary muscle and the hypoxic retinal cells.
How Does a Hyperbaric Oxygen Chamber Treat Eye Fatigue?
The key to treating eye fatigue is not simply reducing screen time. Eyes are tired because they lack energy; energy comes from oxygen. Increase the oxygen supply, and the eyes will naturally become less prone to fatigue. The hyperbaric oxygen chamber provides deep oxygenation to the eyes, improves microcirculation, and relieves eye fatigue.
Consider an office worker who spends more than ten hours per day in front of a screen, frequently experiencing dry eyes, eye soreness, and blurred vision in the afternoon, and has tried various eye drops with no lasting effect. He chooses a home hyperbaric oxygen chamber, using it at 1.5 ATA for 60 minutes daily for 4 consecutive weeks.
HBOT significantly increases oxygen supply to ocular tissues and relieves hypoxic fatigue
The retina is one of the most metabolically active tissues in the body and has an extremely high demand for oxygen. Under hyperbaric conditions, the dissolved oxygen content in plasma increases significantly, and this oxygen can freely diffuse into various tissues, including the retina. When ocular cells receive an adequate oxygen supply, the energy metabolism efficiency of mitochondria improves, and the cells’ endurance naturally increases.
HBOT improves ocular microcirculation and helps relieve ciliary muscle spasm
Prolonged near work causes the ciliary muscle to contract continuously, forming accommodative spasm. The contraction of the ciliary muscle requires energy, and energy production depends on an adequate blood supply. By improving systemic microcirculation, HBOT helps the ciliary muscle obtain more oxygen and nutrients while carrying away metabolic waste products such as lactic acid.
HBOT promotes corneal epithelial repair and improves dry eye symptoms
Prolonged screen staring reduces blink rate, breaks the tear film, and exposes corneal epithelial cells directly to dry air, leading to punctate shedding and exposure of nerve endings, which is the source of dryness and stinging sensations. HBOT, by increasing dissolved oxygen concentration in the blood, allows oxygen to diffuse more fully into corneal tissue, providing the energy needed for damaged epithelial cells to repair.
HBOT reduces oxidative stress and protects optic nerve cells
Prolonged eye use and screen blue light exposure generate large amounts of free radicals, causing oxidative damage to photoreceptors and the optic nerve. By activating the body’s endogenous antioxidant enzyme system, HBOT enhances tissues’ ability to combat free radicals, thereby protecting optic nerve cells.

Real Case: A Programmer’s Screen Eye Reversal
Mark works at a tech company, spending more than ten hours per day staring at a screen. Starting from his second year on the job, his eyes began experiencing various problems: around 3:00 PM every day, his eyes would feel as dry as if sand had gotten into them; by evening, he would need to squint to focus on distant street signs. He visited an ophthalmologist, who told him he had mild punctate epithelial erosion on his cornea and advised him to rest more, use warm compresses, and use artificial tears. But his job would not allow him to rest more. At a tech industry conference, Mark heard about the application of hyperbaric oxygen chambers in relieving eye fatigue. With a try-it-out attitude, he set up a home hyperbaric oxygen chamber.
Week 1: Daily 1.5 ATA, 60 minutes. By around day five, he noticed that the onset of afternoon eye dryness had been delayed. It used to start around 2:00 PM; now he could make it to 4:00 PM.
Week 3: The dryness sensation was significantly reduced. His frequency of using artificial tears dropped from five to six times per day to once or twice per day. He noticed an improvement in night driving glare. Although still present, it no longer made him as anxious as before.
Week 6: He returned to the ophthalmologist for a follow-up examination. The doctor’s findings showed that the punctate epithelial erosion had essentially resolved, and his accommodative amplitude had returned to a level close to that of peers of the same age. Both subjective symptoms and objective indicators had significantly improved.
Week 8: Mark had developed the habit of spending one hour in the chamber after work each day. This hour was not only for recharging his eyes but also for rebooting his own brain. After coming out of the chamber, he would have dinner, spend time with family, and look at his phone before bed without his eyes protesting as they used to.
He used to think that if his eyes were tired, a good night’s sleep would fix them. Now he understands that sleep can restore physical energy but cannot restore ocular microcirculation. Some types of fatigue require active oxygen supplementation to resolve.
In the digital age, what is truly practical is not returning to a screen-free life, but providing the eyes with the nutrition they truly need. Oxygen is the most basic, most fundamental, and most irreplaceable nutrient for the eyes. The Shell Cabin is not only a healing space where you can retreat after work every day to recharge your eyes, but also a reliable partner guarding your vision in the screen age.
