Astringent eyes that cannot sleep are likely to be a case of dry eyes. Generally, dry eye is divided into insufficient secretion of tears and poor quality of tears, usually young people are related to insufficient secretion of tears, caused by excessive use of electronic devices, especially cell phones and computers in close proximity. This condition is treated by replenishing artificial tears with eye drops for alternative treatment, such as Hailu and Bright Vision, which are preservative-free types and have minimal side effects even with long-term use. Older people commonly suffer from a lack of tear quality, usually due to a lack of lipoprotein-like substances. You can supplement lipoprotein-based eye drops, such as polyethylene glycol and polyvinyl alcohol eye drops, and you can assist with hot compresses at night, using a warm towel to warm the eyes for 5-10 minutes before going to sleep, and you will feel more comfortable.
