Frequently Asked Questions
Answers to common questions about eye symptoms and when you should seek professional eye care.
Can blurry vision be an emergency?
Yes. Sudden blurry vision—especially when accompanied by severe eye pain, flashes of light, new floaters, or a curtain over your vision—should be evaluated immediately.
Are flashes of light always serious?
New flashes of light can be a warning sign of a retinal tear or retinal detachment, particularly when accompanied by a sudden increase in floaters or vision loss. Prompt evaluation is recommended.
Are floaters normal?
A few floaters are common with aging. However, a sudden increase in floaters—especially with flashes of light—should be evaluated promptly.
Can dry eyes cause blurry vision?
Yes. Dry eye disease commonly causes fluctuating blurry vision that often improves after blinking or using lubricating eye drops.
Should I go to the emergency room for eye pain?
Severe eye pain, particularly when associated with vision loss, redness, nausea, trauma, or chemical exposure, should be treated as an emergency.
Can allergies make my eyes red and itchy?
Yes. Allergies commonly cause itching, redness, tearing, and eyelid swelling. However, severe pain or decreased vision suggests another condition that requires prompt evaluation.
When should children with eye symptoms be examined?
Children should be evaluated promptly if they develop eye injuries, persistent eye crossing, unusual eye movements, significant redness, or sudden vision changes.
How do I know if my symptoms are urgent?
Symptoms such as sudden vision loss, flashes of light with floaters, severe eye pain, chemical injuries, eye trauma, or a curtain over your vision require immediate medical attention.
