Glaucoma: A Silent Threat with 10 Telltale Signs

8. Nausea

Eye pain and headaches, in addition to issues with vision, can cause nausea. If a glaucoma attack occurs suddenly enough, nausea may result in vomiting. Many glaucoma attacks occur in dark rooms because the pupils dilate to match the light level. This means a person with glaucoma is more likely to feel nausea in places such as movie theaters. In some cases, their vision issues may cause dizziness that intensifies nausea and can also lead to vomiting.
