Tea drinkers have healthier eyes
Studies by researchers at the University of California show that people who drink hot tea on a daily basis are 74 percent less likely to develop glaucoma than those who do not.
Immediately after the study, the researchers said that this effect may not be related to the tea itself and may be due to another habit in tea lovers.
For example, tea lovers may have a special habit or lifestyle that reduces the risk of glaucoma. Further studies show that this effect is not seen in mint tea, iced tea and coffee and is limited to hot tea.
This study requires further studies to examine the exact impact of hot tea or the lifestyle of tea fans on eye health.
Glaucoma is caused by impaired blood flow to the optic nerves and progresses over time. This complication is usually associated with increased eye pressure.
Studies show that glaucoma has genetic roots and may have no symptoms for the rest of its life. Due to the increase in intraocular pressure, the optic nerves that transmit images to the brain are damaged and vision gradually decreases.
This condition can lead to blindness if left untreated. The disease is usually asymptomatic and painless in the early stages, so people with a family history of the disease and middle-aged and elderly people are recommended to be checked periodically and at least once a year by an ophthalmologist.
In addition to a family history, diabetes is one of the most important risk factors for this complication.
What causes glaucoma?
Glaucoma occurs when the pressure of the fluid inside the eye increases and this fluid does not circulate in the eye as it should.
Naturally, there is a fluid between the cornea and the lens of the eye called the aqueous humor, which is secreted from the capillaries and provides nutrients and oxygen to the lens and the cornea, and excretes waste products through the blood.
The fluid together with the vitreous keeps the internal pressure of the eye constant and maintains the spherical shape of the eye. If there is a disturbance in the purification of the liquid and the liquid is not reabsorbed as quickly as it is secreted, the pressure in the eye will increase and a complication of blackheads will occur.
In addition to hereditary factors, severe eye infections, chemicals, inflammatory diseases, and obstruction of blood vessels inside the eye are also uncommon causes of glaucoma. Glaucoma usually affects both eyes; But it may be more severe in one eye.
