Common refractive errors cause a lot of vision problems in Derry . Keep reading to learn about some of the most common types of refractive errors and how your eye doctor can help you correct them:
Myopia, or nearsightedness, prevents people from being able to see far away objects clearly. Instead of hitting the retina as it does in a healthy eye, myopia causes the light to focus just in front of the retina. This causes far away objects to appear blurry. If you cannot see objects that are far away, your eye doctor can set you up with glasses or contact lenses to correct the refractive error so you can see clearly.
This condition, which is also known as farsightedness, makes it difficult for a person to look at objects that are close by. Some people have very slight cases of hyperopia and might not even realize there is something amiss with their vision. Other people have blurry vision that makes it difficult to see objects that are close and those that are far away. If you experience any blurriness in your vision, you should schedule an appointment with your eye doctor to get the treatment that you need to correct this issue and improve the way you see.
When the light cannot focus evenly across the retina, it leads to a condition called astigmatism. People who suffer from astigmatism often see objects as blurry or stretched out. People can have astigmatism in combination with other refractive errors. Regular eye exams help your doctor check on the condition of your eyes and see if astigmatism is causing any of your problems.
Some people develop presbyopia as they age, which keeps them from being able to focus on certain objects that are up close. This condition occurs when the lens cannot change shape to focus. Talk to your eye doctor about any changes in your vision so he or she can work on finding the right treatment for you.
