As of May 2021, at least 11 mountaineers have died on Mount Everest during the spring climbing season. This has been one of the deadliest seasons in recent years, with several deaths attributed to overcrowding, exhaustion, and altitude sickness. The high number of fatalities has raised concerns about the safety and management of climbing on the world's highest peak. **

Mountaineers use an oxygen device at altitudes of around 4000m because the air at higher altitudes contains less oxygen, making it harder for the body to function properly. This can lead to symptoms of altitude sickness, such as dizziness, fatigue, and shortness of breath. Using an oxygen device helps to supplement the body's oxygen levels, reducing the risk of altitude sickness and allowing the mountaineer to continue climbing safely. **

Mountaineers or climbers retrieve the climbing rope and pitons/eye anchors when rappelling by using a technique called "retrievable rappel." This involves threading the rope through the anchors and then pulling one end of the rope while rappelling down, which allows the rope to be retrieved once the descent is complete. At the bottom of the valley, climbers can retrieve the ropes by either walking to the base of the climb and pulling the ropes down, or by using a technique called "releasable anchor," where the rope is threaded through the anchor in a way that allows it to be easily pulled down from the top once the climbers have descended. **

No, it is not true that many mountaineers claim to have reached the summit even though they have not. While there have been cases of false claims of summiting mountains, it is not a common occurrence among experienced mountaineers. Reinhold Messner, a renowned mountaineer, is known for his honesty and integrity in his climbing achievements. He is the first person to climb all 14 peaks over 8,000 meters without supplemental oxygen and is widely respected in the mountaineering community for his accomplishments. **

Ophthalmology is the branch of medicine that deals with the diagnosis and treatment of eye disorders and diseases. Ophthalmologists are medical doctors who specialize in the medical and surgical care of the eyes. They are trained to provide a wide range of eye care services, including performing eye exams, prescribing corrective lenses, diagnosing and treating eye conditions such as cataracts, glaucoma, and macular degeneration, and performing eye surgeries. Ophthalmology is a crucial field in maintaining and improving the health and function of the eyes. **

The ophthalmologist may use a variety of eye drops depending on the specific condition being treated. Some common eye drops used by ophthalmologists include artificial tears for dry eye, antibiotic or antiviral eye drops for infections, steroid eye drops for inflammation, and dilating eye drops for eye exams. Additionally, ophthalmologists may also prescribe medicated eye drops for conditions such as glaucoma or allergies. It is important to follow the ophthalmologist's instructions for using the prescribed eye drops to ensure proper treatment and care for the eyes. **

During an eye examination at the ophthalmologist, the patient's medical history and any current eye issues are discussed. The ophthalmologist then performs various tests to assess the patient's vision, eye pressure, and overall eye health. This may include using a chart to check visual acuity, examining the eyes with a light, and using special instruments to look at the back of the eye. Based on the results of these tests, the ophthalmologist can diagnose any vision problems or eye conditions and recommend appropriate treatment. **
