The cornea is the clear, protective layer at the front of your eye. It bends light and helps you see, but it can be at risk for infection and irritation and could be the reason behind your blurry vision. Robert Bentz, DO, and Miriam Farag, OD, FAAO, provide general cornea care and treat a range of common cornea problems at Bentz Eye Center in West Palm Beach, Florida.

Your cornea is the outermost portion of your eye. It’s clear and thin, and it covers your iris and pupil. Corneas are made of five distinct layers and their job is letting light into your eye.
Corneas work with other components in your eye to bend the light, which is how your eyes focus. In fact, corneas are responsible for up to 75% of your eye’s focusing ability.
In your eye, the cornea and lens work together to focus light. The focused light is then sent to your brain for interpretation, and you see images. The cornea and lens are both curved, and if the curves are mismatched, your vision is blurry.
Nearsightedness, farsightedness, and astigmatism are common refractive errors that develop when the cornea isn’t curved correctly. These refractive errors make your vision blurry because the light isn’t focused properly.
Along with blurry vision, cornea problems might also affect the health of your eyes. Other symptoms include:
If you notice changes in the way your eyes look or feel, make an appointment with your eye doctor.
Since your corneas are on the outside of your eye, they’re susceptible to a range of injuries, irritation, and infection.
Allergens from dust, pollen, and other environmental irritants can get into your eyes and trigger irritation. Allergies can make your corneas more likely to develop an infection, such as conjunctivitis (pinkeye).
A corneal abrasion is a scratch on the surface of your eye. Foreign objects in the eye, like a fingernail, can scrape the surface and cause discomfort. Mild abrasions often heal on their own, but severe abrasions may require treatment to minimize damage.
Allergies, abrasions, and other problems can lead to corneal infections. Wearing contact lenses can cause an infection that leads to keratitis, or inflammation of the cornea. Keratitis often causes severe pain and vision changes.
Your eyes need tears to keep them moist and comfortable. Dry eye is a condition that occurs when your eyes don’t make enough tears, and it can lead to dry corneas, irritation, and other symptoms.
Your corneas protect the internal elements of your eyes and help you see clearly. When something’s wrong with your corneas, it can affect your eye health and your vision.
