Glaucoma symptoms

glaucoma symptoms

Glaucoma symptoms are the signs that your eyes might be losing vision because the optic nerve is being damaged. In many cases there are no obvious warning signs at first, so the condition can creep up slowly without you noticing. Common changes people report include gradual loss of side vision, blurred vision, seeing halos around lights, and in some types sudden eye pain with redness, nausea, and headache. Symptoms vary depending on the type of the condition — some forms progress quietly over years, while others come on quickly and are very painful. It matters because damage from this condition is permanent: once nerve fibers are lost, the vision they carried can’t be restored. Early detection and treatment can often slow or stop further damage, preserving the vision you have. People who are older, have a family history, are very nearsighted, or have other health issues are at higher risk and should have regular eye checkups. If you notice any changes in your vision, persistent eye pain, or halos around lights, prompt evaluation by an eye professional is important to protect your sight.
