When the eyes are dry, many people think they need to be cooled, so they choose eye drops that can bring a cool feeling. The ingredients of eye drops that bring coolness are mostly pearl liquid, borneol, mint, camphor, bear bile, houttuynia cordata and so on. And most of them have no relevant research results on their mechanism of action, adverse reactions and toxic reactions, so the risk of this kind of eye drops is unknown.
Many people feel that their eyes are inflamed and uncomfortable, and they suspect bacteria, so they want to use anti-inflammatory and antibacterial eye drops. Random abuse can easily lead to drug-induced dry eye, hormonal cataract, and even eye flora imbalance, resulting in drug resistance.
There is also an eye drop for removing red blood, which has a remarkable effect of contracting blood vessels and can reduce eye congestion. But the core component of this kind of eye drops is "adrenergic receptor agonist". Frequent use will cause the risk of dependence, such as dilated pupils and enlarged blood vessels, and even lead to acute attack of angle-closure glaucoma.
The safest eye drops are artificial tears, and the main component is simulated natural tears. When the eyes are dry, the symptoms can be relieved appropriately, and it does not contain any anti-allergic, anti-inflammatory and anti-fatigue components. If you feel dry eyes, have no time to rest or are still uncomfortable after rest, you can try dropping some artificial tears. Only need 1 drop each time, and use it within 4 times a day to prevent interference with normal tears. If you still feel unwell after intravenous drip, you should seek medical advice promptly.
