Eyes are the window with that people can observe the world, but many people still don’t know how to keep their eyes healthily. According to the British “Daily Mail” report, scientists at University College London and Morfield Eye Hospital warned that people should pay more attention to eye hygiene, especially those who use contact lens.
Researchers say the number of people suffering from eye diseases has tripled since 2011, and these diseases can cause blindness. It is understood that people wearing contact lenses are more susceptible with the disease of Acanthamoeba keratitis. Contact lens are exposed to unclean water and then contact with the eyes, which can easily cause eye infection.

The researchers found that people who did not wash their hands before wearing contact lens and who did not use contact lens syrup had a two-fold higher risk of contracting Acanthamoeba keratitis than others. In addition, wearing contact lens while taking a bath also increases the probability of illness.
The new study shows that eye health is not determined by luck, and people should do a lot to protect their eyes and vision. Such as:

Swim every day
Swimming is a great benefit to the body’s cardiovascular system, but if you don’t wear a goggle while swimming, your eyes may be damaged, especially when you open eyes with contact lens under the water. O’ Brien said that water in all types of waters can cause bacterial infections in the eyes. “Wearing contact lens makes eyes infection, and bacteria attached to the surface of the glasses can cause redness.”
Therefore, if you want to wear glasses under water, it is best to use disposable contact lenses and goggles, or spend money with a special goggles for myopia.
Dont use expired mascara
Many people use mascara, but mascara condenses into pieces after three or four months usually, and people aren’t willing to buy new ones because mascara is too expensive.
It is told that mascara may contain bacteria. The use of expired mascara may cause redness, infection, and even rare diseases and even blindness, while unopened cosmetics can generally remain unchanged for several years.

In addition, eye makeup such as eyeliner may also cause eye infections. Experts recommend that you can cut the pen before using the eyeliner to prevent bacteria from being transferred from the pen to the eye. Experts also said that the use of inferior, unhygienic false eyelashes will increase the risk of eye infections, so it is important to choose a reputable make-up artist during makeup.
Do eye examination
O’Brien said that eye health tests can detect health problems such as diabetes, glaucoma and high blood pressure, which can have serious effects on eye health and even blindness. Even arthritis, a disease that seems to have nothing to do with the eye, can be detected by eye examinations. If not treated promptly, arthritis can also affect the health of eyes.
In general, an ordinary person should have an eye examination twice a year. If the eye itself has a disease or is older than 70 years old, a physical examination should be performed every 12 months.
In addition, children under the age of 16 are experiencing rapid changes in vision at this age, so an eye examination should be performed each year.
Dont always look at the phone
Research at the University of Toledo has shown that cell phone, computer or television can always cause danger to eye health. The blue light emitted by these electronic screens is received by the visual cells in the retina and punishes the toxic chemicals, eventually killing the photoreceptor cells in the eye. The longer the staring at the screen, the more fragile the eye is.

Researchers say people shouldn’t use a cell phone or tablet in the dark, and using these electronic devices in the dark can spread the pupils and make the eyes danger. Experts recommend wearing contact lens with anti-glare coatings or adding a Blu-ray filter to the screen when using devices such as mobile phones.

 Dont smoke much
People know that smoking is harmful to health, but few people can notice that smoking can also cause damage to the eyes. O’Brien said that smoking increases the risk of cataracts and age-related macular degeneration, and macular degeneration is one of the main causes of vision loss.
Dont forget to wear sunglasses
People may think that winter is coming, the sunshine time is getting softer. and there is no need to wear sunglasses when going out. But O’Brien said that ultraviolet light still affects the eyes in winter. “In general, ultraviolet light is stronger in summer, but 80% of UV radiation can still pass through the clouds to the ground, which means that even on cloudy days, ultraviolet rays can cause danger to the eyes.”
What’s more, it is also a misunderstanding that black lenses can protect the eyes from UV damage. O’Brien said that the color of the sunglasses has no effect on the UV protection. Unless the sunglasses provide good UV shielding, the color of the lens will only spread the pupil and cause the eyeball to absorb more UV rays.
O’Brien suggested that when buying sunglasses, you can see if the glasses have the CE mark (the EU’s UV protection standard). Such sunglasses can prevent 95% of the UV rays from being absorbed by the eyes.

Besides,the eye is more sensitive to ultraviolet light than the skin, and prolonged exposure to ultraviolet light can also cause eye diseases such as cataracts and macular degeneration.

Dont use fan too much

Using a fan all night can also cause irritation to the eyes and dry up the eyes. When people sleep, the fan will blow allergens such as dust or pollen to the eyes, so the eyes may be stimulated and feel uncomfortable when wearing contact lens the next morning.
To avoid eye irritation, the bedroom should be cleaned thoroughly. the fan blades cleaned, and the contact lens is often used to clean the stains on the lens. In addition, you can set the timing of the fan to avoid eye irritation after falling asleep.
Dont use more eye drops
Moderate use of eye drops can protect the eyes, but excessive use of it can be counterproductive. O’Brien said that after the medicine effect in the eye drops subsides, the blood pressure in the eyeball will rise and the eye will still “bounce” into red eyes.
