Have you ever noticed your eyes looking red after a long day and assumed it was just fatigue? While tiredness can play a role, eye redness can actually signal a wide range of issues—from simple dryness and allergies to infections or even serious conditions like uveitis and glaucoma.

Many people believe that “normal” eye pressure means they’re safe from glaucoma—but that’s not always true. Normal-Tension Glaucoma (NTG) can damage the optic nerve even when intraocular pressure (IOP) appears normal.

Normal eye pressure doesn’t always mean healthy eyes. Learn how Normal-Tension Glaucoma damages vision even with normal readings—and how to protect your sight.
