红眼是一种常见问题，可能影响单眼或双眼。发红是因为眼睛表面的血管。这些血管因为刺激或疾病而扩张。
如果出现以下情况，请立即就医：
- 视力骤变。
- 红眼伴有严重头痛、眼睛疼痛、发热，或者光线开始伤害眼睛。
- 伴有胃部不适或呕吐。
- 红眼由异物或化学物质溅入眼睛引起。
- 您突然开始看到光源周围有光晕。
- 眼睛有异物感。
- 眼内或眼周肿胀。
- 无法睁开眼睛或保持眼睛睁开。
与医务人员约诊
有时，短暂的红眼无需担心。如果您认为发红是由非处方滴眼液引起，不妨试用其他品牌或暂停使用滴眼液。
如果您的红眼几天后仍未消失，尤其是如果长时间有浓稠脓液或黏液，请联系医务人员约诊。
如果出现以下情况，请联系眼外科医生：
- 眼睛发红并伴有疼痛。
- 曾经接受过眼科手术或眼部注射。
