Eye Health & Vision Care Glossary
Understanding Common Eye Conditions and Vision Terms
At Fort Pierce Vision Care, we believe patients should feel confident and informed about their eye health. This glossary explains common eye conditions, vision problems, and optometry terms you may hear during your eye exam.
If you have questions about any of these conditions or need to schedule an eye exam in Fort Pierce, FL, our team is here to help.
Amblyopia (Lazy Eye)
Amblyopia, often called “lazy eye,” is a condition in which one eye does not develop normal vision during childhood. Even with glasses or contact lenses, the affected eye may not achieve clear 20/20 vision. Amblyopia typically occurs when the brain favors one eye over the other, causing the weaker eye to develop poor visual ability. Early diagnosis and treatment during childhood are important for improving vision.
Astigmatism
Astigmatism is a common vision condition caused by an irregular shape of the cornea or lens. Instead of focusing light evenly on the retina, the eye creates blurred or distorted vision at both near and far distances. Astigmatism can often occur along with nearsightedness or farsightedness and is typically corrected with prescription glasses, contact lenses, or specialized lenses.
Cataracts
A cataract occurs when the natural lens of the eye becomes cloudy, leading to blurry or dim vision. Cataracts usually develop slowly with age and may cause symptoms such as glare from lights, faded colors, or difficulty seeing at night. Cataracts are very common and can often be treated successfully with cataract surgery when vision becomes significantly affected.
Eye Teaming (Binocular Vision)
Eye teaming, also known as binocular vision, refers to how well both eyes work together to focus on the same object. When the eyes are properly aligned, the brain combines the images from each eye to form a single clear image. Poor eye teaming can cause symptoms such as double vision, eye strain, headaches, or difficulty reading.
Farsightedness (Hyperopia)
Farsightedness, or hyperopia, is a vision condition in which distant objects may be seen clearly, but nearby objects appear blurry or require extra effort to focus. People with hyperopia may experience eye strain, headaches, or fatigue when reading or doing close work. Glasses or contact lenses are commonly used to correct farsightedness.
Glaucoma
Glaucoma is a group of eye diseases that can damage the optic nerve, often due to increased pressure inside the eye. Because glaucoma typically develops slowly and without early symptoms, it is sometimes called the “silent thief of sight.” Regular eye exams are important for detecting glaucoma early and preventing permanent vision loss.
Macular Degeneration
Macular degeneration is a condition that affects the macula, the central part of the retina responsible for sharp, detailed vision. This condition can make it difficult to read, drive, recognize faces, or see fine details. Age-related macular degeneration (AMD) is one of the leading causes of vision loss in adults over age 50.
Nearsightedness (Myopia)
Nearsightedness, or myopia, is a vision condition in which close objects appear clear but distant objects look blurry. Myopia occurs when the eye grows too long or the cornea is too curved, causing light to focus in front of the retina rather than directly on it. Glasses or contact lenses are commonly used to correct nearsightedness.
Presbyopia
Presbyopia is the natural loss of the eye’s ability to focus on nearby objects as we age. It usually becomes noticeable in the late 30s or early 40s and may cause difficulty reading small print or needing to hold reading material farther away. Reading glasses, bifocals, progressive lenses, or contact lenses are commonly used to help correct presbyopia.
