Does diving affect eyesight?
Ocular decompression sickness (DCS) is a relatively uncommon event, but one which does occur and it is very important that divers be aware of this possible presentation of DCS. Symptoms may include: Loss of vision. Blurred vision.
Which health problem is caused by diving?
High-pressure nervous syndrome (HPNS) is a neurological and physiological diving disorder that results when a diver descends below about 500 feet (150 m) while breathing a helium–oxygen mixture. The effects depend on the rate of descent and the depth.
What injuries are related to diving?
The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.
Can I scuba with glasses?
Can I Wear Glasses while Scuba Diving? Unfortunately, no. The reason why you cannot wear go scuba diving with glasses is that your glasses will sit on your nose and hook onto your ears. For this reason, a diving mask will not be able to fit onto your face or seal properly.

What is diving sickness?
Decompression sickness, also called generalized barotrauma or the bends, refers to injuries caused by a rapid decrease in the pressure that surrounds you, of either air or water. It occurs most commonly in scuba or deep-sea divers, although it also can occur during high-altitude or unpressurized air travel.
What do divers suffer from?
Decompression sickness (abbreviated DCS; also called divers’ disease, the bends, aerobullosis, and caisson disease) is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during decompression.
What effects does diving have on the body?
As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.
How does diving affect the body?
Can I scuba dive without glasses?
The answer is short and simple. No you cannot do scuba diving with glasses. The design of eyeglasses means that the arms of the glasses that clip over your ears do not allow the plastic or silicon skirt of the dive mask to seal correctly over your face.
Do glasses work underwater?

Can you see underwater if you wear glasses?
Does diving cause brain damage?
Acute decompression illness (DCI) involving the brain (Cerebral DCI) is one of the most serious forms of diving-related injuries which may leave residual brain damage. Cerebral DCI occurs in compressed air and in breath-hold divers, likewise.

Can you wear lenses while diving?
For diving, you should always wear soft contact lenses. Hard contact lenses are gas-permeable, which means they allow gas to pass through your eye. With hard contact lenses, nitrogen bubbles can form between your lenses and your eyes, causing blurry vision, discomfort, and even eye pain.
How do people with glasses go diving?

The occasional glance should be OK, but extended eye opening underwater can cause damage. “The eye becomes red, irritated. You might become photophobic, or sensitive to light. Your vision might blur a little bit, and your eyes are going to feel irritated or even, frankly, painful,” says Dr.
Is diving bad for Your Eyes?
Diving exposes the eyes to increased pressure. While most of the time this has little or no negative effects on the diver, increased eye pressure in scuba diving can result in ocular decompression sickness or other problems. In regard to personal eye health and diving, here are some common questions with corresponding answers:
What are the health risks associated with scuba diving?
Mental health disorders (such as anxiety, claustrophobia, or substance abuse) and disorders affecting central nervous system higher function and consciousness (such as seizures) raise special concerns about diving fitness.
Is scuba diving safe for glaucoma patients?
Although this would seem to be a logical conclusion, diving thus far has not been shown to be a problem for glaucoma patients.
What are the different types of diving injuries?
DIVING DISORDERS 1 Barotrauma. Barotrauma is an injury to soft tissues resulting from a pressure differential between an airspace in the body and the ambient pressure. 2 Decompression Illness. Decompression illness (DCI) describes the dysbaric injuries (such as AGE) and decompression sickness (DCS). 3 Other Conditions Related to Diving.
