Your eyes are working for you consistently, playing an essential role in helping you navigate, read, write and view. Sometimes when you go for an eye-checkup to an ophthalmologist or an optometrist, there are many medical terms that you hear, related to eye care that are difficult for a common man to comprehend. Below are some of these terms that will be helpful in understanding what your ophthalmologist, uses.
Age-Related Macular Degeneration (AMD): This is a problem of the retina, which happens when a part of the retina called the macula gets damaged. It impacts your central vision, and you are not able to see fine details. For instance, when you are looking at the clock, you will be able to view the numbers clearly, but not the hands and central part.
Amblyopia: It is also known as lazy eye and is typically an infant vision development problem. This condition develops when your eye doesn’t achieve the normal visual acuity. It can be corrected with a patch or vision therapy, which strengthens the vision of the weak eye and makes both the eyes work together. A child with a lazy eye will view alphabets in the below manner.
Astigmatism: It develops when the front surface of the eye, i.e. the cornea or the lens has mismatched curves, thus blurring the vision. Usually, the surface of the eye is round in shape, but in such a condition it is oval shaped. This common and curable condition can exist with nearsightedness and farsightedness simultaneously. Its symptoms include blurred vision, eye strain, headache or squinting.
Cataract: It is a dense, cloudy area, which forms in the eye lens. Cataract develops slowly interferes with the eye vision, and can form in both the eyes. Different types of cataracts are formed due to different health issues like diabetes, trauma and some are age-related. Surgery is recommended when cataract prevents you from going about your daily activities, such as reading or driving.
Glaucoma: It damages the optic nerve of the eyes and usually happens when there is fluid build-up in the front part of the eyes. This extra liquid puts pressure in the eye, damaging the optic nerve. If left untreated, it can get worse and even cause permanent vision loss. Most people with Glaucoma have no early symptoms. So, if you are over 40 years, or have a family history of this disease, then it is essential to get an eye examination done, periodically.
Hyperopia: It is also known as farsightedness, a vision condition due to which you can see distant objects clearer as against close ones. Its detection requires a comprehensive eye examination.
Myopia: It is a common vision condition in which a person can view close objects clearly but not the farther ones. It is also known as nearsightedness. Even a basic eye examination can determine such a condition. You can fix it with eyeglasses, contact lenses or refractive surgery.
Presbyopia: It is an ageing eye condition, which impacts the ability of the person to focus on nearby objects. This condition affects your ability to read small prints including messages on the smartphone. To correct presbyopia, eyeglasses are most prescribed.
Visual Acuity: It is a way to examine the ability of the eyes to distinguish between shapes and details of a particular object from a certain distance. Visual Acuity also refers to clarity of vision and helps in detecting any vision changes.
Early diagnosis of most of the above conditions can keep your eyes healthy. In fact, prescription eyeglasses or contact lenses can also correct some of the conditions like Astigmatism, Hyperopia, Myopia, Presbyopia and Visual Acuity. Getting your eyes tested at least once a year is recommended my practicing optometrists and ophthalmologists. If you want to get a comprehensive eye test done or buy eyeglasses and contact lenses, then you can book an appointment online or visit a Vision Express store near you.
