What causes bloodshot and itchy eyes?

1. Abuse of eye drops causes itchy and congested eyes

When the eyes feel uncomfortable, many people will abuse eye drops at will. In fact, eye drops also contain preservatives or hormones. Using eye drops too frequently will cause the preservatives in the drops to cause certain damage to the surface of the eyeball. Long-term abuse will reduce the resistance of the eyes, cause corneal damage, and cause itchy and congested eyes.

2. Excessive use of eyes causes itchy and congested eyes

With the popularization of television and computers, many people spend a long time surfing the Internet, watching TV, playing with mobile phones, etc., and staring at electronic screens for a long time without blinking, which leads to excessive eye use and severe visual fatigue, causing itchy, dry, and congested eyes.

3. Allergic factors cause itchy and congested eyes

Itchy and bloodshot eyes are also related to eye allergies. If the itching and redness of the eyes is obviously seasonal and is accompanied by allergic symptoms such as itchy nose and sneezing, this is caused by eye allergies. For example, contact with drugs, chemicals, flowers, dust, animal dander, etc. can cause eye allergies, and in severe cases conjunctivitis may occur. Especially for people who are prone to allergies, when they come into contact with allergens and cause allergic reactions, they are likely to experience symptoms such as itchy eyes and bloodshot eyes.

Causes of red eyes

During every holiday or weekend, it is inevitable to see a group of people with red bloodshot eyes. Why is that? This is caused by fatigue, but this situation is not serious and can be repaired with a little rest. But the reasons for red bloodshot eyes are far more than this, there are other reasons, as follows:

Reason 1: Red blood streaks caused by climate and environmental factors

Long-term living in a relatively harsh living environment, such as the thin air on the plateau and skin hypoxia, leads to an increase in the number of red blood cells and compensatory dilation of blood vessels. Over time, vasoconstriction dysfunction causes red blood streaks on the face.

Reason 2: Red blood streaks caused by the abuse of cosmetics

Or long-term "skin package care" can also cause red blood streaks on the face. And the sequelae caused by improper skin peeling. The acidic components of skin peeling products destroy the protective effect of the skin's stratum corneum and the elasticity of capillaries, causing the capillaries to dilate or rupture.
