The academics describe the best way to open the bottles in order to minimise risk.
Apart from direct eye symptoms, an individual could also experience excessive lacrimation, photosensitivity, headaches and nausea.

It could also show corneal oedema which ...
Rubbing or applying force to the affected areas should be avoided as it may cause further damage such as abrasions. [2] The use of ibuprofen and tetanus toxoid is recommended for pain relief or to reduce swelling or inflammation. [1] For severe injuries, iloprost or thrombolytics may be used.
