2. Ocular Hypertension
Glaucoma causes your eye pressure to increase due to fluid buildup, coupled by your eye’s inability to regulate the internal pressure. This causes parts of your eye to expand, pushing against the delicate optic nerve and leading to vision problems (or loss).
It’s possible to have no obvious signs of glaucoma while also showing higher-pressure readings, making you a “glaucoma suspect,” notes the American Academy of Ophthalmology. Your doctor or eye care professional will be able to determine eye pressure quickly with that little blast of air during a routine exam.
