Red eyes are one of the most common eye concerns people experience, often linked to fatigue, allergies, or irritation. However, what many don’t realize is that persistent red eyes can sometimes signal an underlying eye disease or health problem.
In this article, York Optometry Clinic explains why red eyes should never be ignored, what may be causing them, and when it’s time to seek professional help.

What Do Red Eyes Really Mean?
Common Causes of Red Eyes
Here are some of the most common causes York Optometry Clinic identifies during examinations:
Allergies or Dry Eyes – Often triggered by pollen, dust, or environmental factors.
Eye Fatigue – From excessive screen time or lack of sleep.
Contact Lens Overuse – Poor hygiene or extended wear can cause irritation.
Infections – Such as conjunctivitis (pink eye), which causes redness, discharge, and discomfort.
Injury or Foreign Object – Even minor trauma can cause visible redness.
If redness persists beyond a few days, or is accompanied by pain, discharge, or blurred vision, it may point to something more serious.
When Red Eyes Indicate Serious Conditions
Some red-eye causes can threaten your vision or overall health if left untreated. York Optometry Clinic highlights the following serious conditions:
Uveitis – Inflammation of the eye’s middle layer, often linked to autoimmune diseases.
Glaucoma – A buildup of pressure in the eye that can lead to vision loss.
Corneal Ulcer or Infection – Usually caused by bacteria or improper contact lens use.
Ocular Herpes – A viral infection that can cause scarring and permanent damage if untreated.
Early detection by an optometrist can help prevent long-term vision complications.
How Red Eyes Can Reflect Your Overall Health
High blood pressure (Hypertension)
Diabetes
Autoimmune diseases like lupus or rheumatoid arthritis
Thyroid disorders
Even certain cancers that affect the blood or immune system
This is why routine eye exams are not only about vision—they’re about your whole-body health.
When to See an Optometrist
If you experience any of the following symptoms along with red eyes, book an appointment with your optometrist immediately:
Eye pain or swelling
Sudden blurred vision
Sensitivity to light
Persistent redness lasting more than a few days
Discharge or crusting around the eye
The York Optometry Clinic team uses state-of-the-art diagnostic equipment to determine the cause and provide targeted treatment to restore comfort and clarity.
Preventive Eye Care Tips

Follow the 20-20-20 rule for screen time: every 20 minutes, look 20 feet away for 20 seconds.
Avoid rubbing your eyes.
Remove makeup and contact lenses before sleep.
Stay hydrated and maintain a balanced diet rich in vitamin A and omega-3s.
Schedule regular eye exams — even if your vision feels fine.
