One of the leading causes of vision loss in people who are age 50 or older is age-related macular degeneration (AMD). This common eye condition leads to damage of a small spot near the center of the retina called the macula. The macula provides us with the ability to clearly see objects that are straight
Diabetes is a condition that involves high blood sugar (glucose) levels. This can affect many parts of the body, including the eyes. One of the most common diabetic eye diseases is diabetic retinopathy, which is also a leading cause of blindness in American adults.
Somewhere around the age of 40, most people’s eyes lose the ability to focus on close-up objects. This condition is called presbyopia. You may start holding reading material farther away, because it is blurry up close. Reading suddenly gives you eyestrain. You might wonder when manufacturers started
The only way to correct the clouded vision caused by advanced cataracts is surgical intervention. If you find yourself pursuing cataract surgery to remove one or both cataract-disease lenses, you may be wondering what surgical approaches are available for treatment.
Although eye surgeons have successfully
With cataract surgery, your ophthalmologist removes the cataract-diseased lens of your eye. The ophthalmologist then replaces your natural lens with an artificial one.
This outpatient procedure is generally safe and takes less than an hour. Your ophthalmologist will dilate your pupil
Normal sight includes central vision (the field of view straight ahead) and peripheral vision (the field of view outside the circle of central vision). The inability to see within a normal range of view often indicates peripheral vision loss. In severe cases of peripheral vision loss, individuals only
As we age, our eyes—like the rest of our bodies—begin to lose flexibility and strength. When this happens to the lens of the eye and its surrounding muscles, your lens will become stiff. This makes it harder to see close objects clearly because the eyes can't focus properly. It's a natural part of
The condition known as a macular hole refers to a tiny break in the macula that results in blurry or distorted vision. To fully understand the condition, one must understand eye anatomy. The macula is a spot located in the center of the retina (the back portion of the eye). Located where light comes
Nystagmus is a vision condition characterized by repetitive, uncontrolled eye movements. These involuntary eye movements may be side-to-side, up and down, or in a circular pattern, which hinders the eyes’ ability to focus on a steady object. Individuals with nystagmus may hold their heads in unusual
Vitreoretinal surgery refers to a group of surgeries which take place inside the eye's interior where the vitreous (gel-like material) and retina (photosensitive membrane) are located. Vitreoretinal procedures are either performed with traditional surgical tools or lasers, and address a range of ophthalmic
Myopia, or nearsightedness, means that your eyes can see close objects clearly but struggle to see things in the distance. Nearly 30 percent of Americans are nearsighted.
This condition usually develops in children and teenagers, up to about the age of 20. A teacher or parent might notice a child squinting
There are several types of refractive surgery available to correct vision problems caused by refractive errors, including:
LASIK (laser-assisted in situ keratomileusis)
Custom or bladeless LASIK
Photorefractive keratectomy (PRK)
Laser epithelial keratomileusis (LASEK)
A normal cornea — the clear front covering of your eye — has a round curve, like a basketball. However, many people have an irregularly shaped cornea while others have an irregularly curved lens. Both cases can cause light that enters the eye to bend the wrong way, causing blurry vision. This disorder
People with hyperopia, also known as farsightedness, can usually see objects in the distance, but their close vision is blurry. Symptoms of untreated hyperopia include:
Difficulty concentrating on near work, such as reading
Headaches after reading or other activities involving close focus
