Eye Strain and Digital Devices
In our world today, we use screens a lot. This can cause eye strain and red eyes. When we stare at screens for too long, our eyes can get tired and show signs of strain.
Digital Eye Strain

Glaucoma and Red Eyes
Glaucoma is a serious eye condition that increases pressure inside the eye. This pressure can harm the optic nerve, leading to blindness. Red eye is one sign of glaucoma.
Types of Glaucoma
Glaucoma comes in types like open-angle and angle-closure glaucoma. Open-angle glaucoma is the more common form. Angle-closure glaucoma is also called acute glaucoma. It causes severe symptoms and needs quick medical care.
Symptoms of Acute Glaucoma
Acute glaucoma shows symptoms such as severe eye pain, headaches, feeling sick, throwing up, sudden vision loss, and red eyes. It’s key to know these signs for early treatment.
Emergency Treatment
If red eyes and other signs of acute glaucoma show up, get medical help right away. This is an emergency. Fast action can save your sight. Regular eye checks are vital, especially for those at greater risk. To learn more about glaucoma’s connection to red eyes, check out this resource.
Subconjunctival Hemorrhage
A subconjunctival hemorrhage happens when a blood vessel on the eye’s surface breaks. This causes a clear red patch to form. Often, this condition doesn’t hurt, and many might not see it until looking in a mirror.
It can occur from simple things like coughing, sneezing, or straining too hard. Understanding why red eyes happen can clear up a lot of questions about this condition.
Causes and Symptoms
Intense activities that raise blood pressure can cause a subconjunctival hemorrhage. This includes tough exercise, severe coughing, or lifting heavy things. An injury to the eye might also lead to a hemorrhage.
The main symptom is a visible red patch on the eye’s white part. This redness does not hurt vision. Also, there’s no discharge or serious discomfort.
When to Seek Medical Help
Usually, a subconjunctival hemorrhage is not a big deal and gets better by itself in two weeks. But, there are times when you should see a doctor. If the redness stays for more than two weeks, comes back often, or if there’s pain, vision changes, or bleeding in other eye areas, get medical help.
In some scenarios, these signs could mean something more serious. So, it’s wise not to overlook them.
