What is the disease of bloodshot eyes?

The eyes are not only our windows to the world, but the tiny changes inside the eyes are actually a true reflection of our body's health status. We often describe babies' eyes as transparent as glass, but as they grow older, their eyes will become more and more cloudy and their color will slowly turn yellow. So when there are bloodshot eyes and yellow spots, is it a normal physiological condition or other diseases? Let's find out the correct reasons below.

1. Visible "yellow spots" on the white of the eye

● Usually pigmentation

The yellow spots/blocks that appear on the whites of the eyes are generally pigmentation of the conjunctiva. If they appear between the whites of the eyes and the black pupils, they are mostly chalazae caused by wind and dust irritation and excessive exposure to ultraviolet rays. Both conditions have no effect on the eyes or vision and do not require treatment, so there is no need to worry too much.

● The "macular spot" in medicine is located at the bottom of the eye and everyone has it.

The "macula" mentioned in medicine refers to a normal structure at the fundus of the eye that everyone has. The macula is the part of the retina with the sharpest vision and is mainly responsible for our central vision. Whether we can see things normally depends entirely on the nerves in the macula, so it is very important. Once the macula is "sick", our vision may be greatly impaired or even blind!

Doctor's reminder:

1. To protect the macula, we need to pay attention to the following in daily life: try not to stare at strong light sources, such as sunlight, lasers, etc., try to avoid direct vision, and remember to wear sunglasses.

2. When you feel that the colors of things you see become darker or distorted, and dark spots or areas appear in front of your eyes, there may be a problem with your macula. You should go to the hospital for a check-up as soon as possible to avoid delaying treatment.

3. People at high risk of eye fundus diseases, such as the elderly over 50 years old, patients with cardiovascular disease, diabetes, and people with severe myopia, should undergo regular fundus examinations every year to prevent the occurrence of macular degeneration.

4. If the whites of a newborn's eyes turn yellow, it is mostly physiological jaundice, which will generally disappear about 10 days after birth. If the whites of an adult's eyes are evenly yellow, it may be a sign of abnormal liver function. It is recommended to go to the hospital for a liver function test as soon as possible.

2. Red bloodshot eyes

● Overuse of eyes or bacterial infection

People who use computers and mobile phones for a long time are prone to overstraining their eyes. Coupled with staying up late and lack of sleep, the capillaries in the eyes will become congested and the red blood vessels in the eyes will increase.

In addition, rubbing your eyes with your hands, or foreign objects entering your eyes, or wearing heavy eye makeup or contact lenses for a long time may cause bacteria or viruses to invade your eyes, causing local infection of the eyes, resulting in congestion, red bloodshot eyes, and redness.

Doctor's reminder:

1. The eyes must have enough "rest" time. For office workers who use their eyes frequently, it is recommended to take a break every hour to relieve visual fatigue. You can intentionally increase your blinking frequency (a new layer of tear film will form every time you blink) to give your eyes a little "massage". You can also leave your seat and walk to the window to look into the distance. The most important thing is to ensure adequate sleep time to effectively reduce the red bloodshot eyes.

2. Doctors do not recommend long-term use of the internet celebrity-sell eye drops for removing red bloodshot eyes. Because it contains tetrahydrozoline hydrochloride, which is only a vasoconstrictor, it cannot make the red blood vessels disappear, but instead forces the blood vessels to contract, making them temporarily "invisible." Long-term use will not only cause dependence, but also lead to insufficient blood supply to the eyes, thereby causing damage to the eyes, such as being more likely to cause visual fatigue and even dry eye syndrome.

3. If your eyes are red and accompanied by eye pain, itching, discharge or a foreign body sensation, you need to see a doctor immediately.
