Eye Symptoms

Why are my eyelids swollen? Why are my eyes so red? Are dilated pupils normal? Learn about all kinds of eye symptoms and their causes and treatments.

Any time we notice a change in our vision or something not quite right with our eyes, it’s natural to head to the internet to look for answers. However, you should always make sure the info you get online is from a reliable source.

Whether your eyes are burning and red, or your eyelids are sore and swollen, or your vision seems blurrier than usual, you’ll find articles below to help you sort out what may be causing your eye symptoms. Our symptoms articles are designed to answer all your questions about the most common eye symptoms (and even some not-so-common symptoms), but they shouldn’t replace a visit to your eye doctor.

Before self-diagnosing — and certainly before self-treating — you should always visit your eye doctor. An eye doctor is the only person who can examine your eye symptoms to give you a correct diagnosis and a safe, effective treatment plan.
