A concise guide to some of the most common vision problems
There are many different types of vision problems that could be affecting your eyesight. But, for the purposes of this guide, we will be focusing on four of the most common causes of impaired vision. These, along with many other vision impairments, are treated with care and precision by the eye care providers at Bogey Hills Vision Center.
Astigmatism is an uneven or irregular curvature of the cornea or lens, in which things do not come to focus at a clear, crisp point inside of the eye. Instead, images are focused at multiple points, causing things to appear blurred or doubled. Other symptoms of astigmatism include the need to squint, eye strain from squinting, headaches and eye fatigue.
In reality, most people have some degree of astigmatism, which is usually present at birth and is believed to be hereditary. In minor cases, treatment may not be required but is certainly beneficial. Moderate to severe astigmatism can be treated with corrective eyewear, contact lenses, or LASIK surgery in many cases.
Farsightedness, medically known as hyperopia, can be a confusing term. Basically the eyeball is shorter in length than it should be, causing things to focus ‘behind’ the back of the eye. However, children and young adults have strong focusing ability in their eyes, and may have no symptoms if a small amount of hyperopia is present. In fact, it is normal and expected for very young children to have some level of hyperopia. However, a moderate amount of hyperopia may cause fatigue, strain, and inattention with near work, because the focusing muscle in the eye has to work extra hard to keep things clear and sharp. If a large amount of hyperopia, is present, the eye may not have enough focusing power, and a person may have poor vision at both distance and near.
If you are mildly hyperopic, your eye care provider may not recommend corrective treatment at all. However, if you are moderately or severely hyperopic, you may have several treatment options available, including eyeglasses and contact lenses. LASIK surgery may not be the best option for those with hyperopia, but a case-by-case evaluation is possible. Your eye care provider at Bogey Hills Vision Center will help you determine the best treatment option for you.
Nearsightedness, medically known as myopia, refers to vision that is good at close range but not at a distance. It generally occurs because the eyeball is longer than it should be and images come into focus before they reach the back of the eye. Myopia most often starts in later childhood and typically progresses until the later teen years. Of interest, there has been a significant increase in myopia in the general population and there have been studies done to help determine the reason. It appears genetics plays a large role, but does not fully explain the large increase. Increased near work and possibly use of electronics may be playing a role, but that in itself does not explain the whole picture, either. Some studies have shown that children that spend more time outdoors have less myopia than their counterparts that spend more time inside, so there may be some part of outdoor play that is important for eye development. Further studies have looked at treatment options to slow down the progression of myopia. Some have been shown to be somewhat effective and may include mulitfocal eyeglasses or contact lenses.
Myopia is diagnosed during comprehensive eye examination and possible treatments include eyeglasses, contact lens, and LASIK. Our doctors will determine the best treatment option for you.
Loss of the ability to focus with nearwork that comes with aging is called Presbyopia. The lens of the eye is continuously growing through life and gradually loses its flexibility, making it harder to focus clearly on close objects such as printed words. This happens to everyone and usually come apparant around ages 40 to 45.
Unfortunately, presbyopia is an inevitable part of aging and cannot be prevented by diet, lifestyle or visual habits. However, it is treatable with several types of corrective lenses including single-vision reading glasses, mulifocal eyeglasses, and monovision or multifocal contact lenses.
