Understanding some of the most common eye disorders can be extremely difficult without the help of your optometrist in Fresno, California. An optometrist has more than enough experience to help their patients understand the similarities and the differences between myopia, hyperopia, astigmatism, and presbyopia. As a patient, if you have questions or concerns about the health of your eyes you need to call your optometrist in Fresno, CA or Kerman, CA at Signature Optometry.


Myopia is the scientific name for what others refer to as “nearsighted.” This is an incredibly common disorder that affects the eyes. Individuals that are diagnosed with myopia can see objects up close but have a problem seeing objects that are far away.


Hyperopia is the scientific name for the condition that is also known as “farsightedness.” Unlike myopia, hyperopia causes individuals to struggle when trying to see objects that are close up. Those that are diagnosed with hyperopia can see objects clearly that are far away. This makes reading and close-range focus very difficult.


Astigmatism is a very common condition that affects millions of people each year. Those that are affected by astigmatism have an abnormal curvature or shape of their cornea. This condition causes blurred or distorted vision. This disorder of the eye is commonly seen in conjunction with other eye disorders; myopia, hyperopia.


Presbyopia is a lot like hyperopia in the fact that those who are affected cannot focus on close-up objects. This disorder is caused by a loss of flexibility of the lens. Unfortunately, this loss of flexibility is a normal aspect of aging and cannot be prevented.
