A concise guide to some of the most common vision problems treated at Downtown Vision Centre and Camas Vision Centre.
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. Clear vision occurs when the light entering the eye converges on the retina. Blurry vision can be caused when the light entering the eye doesn’t converge on the retina. The vision impairments listed below and others are treated with care and precision by the eye care providers at Downtown Vision Centre and Camas Vision Centre.
Astigmatism is an uneven or irregular curvature of the cornea or lens, which results in blurred or distorted vision. 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 or LASIK surgery.
Farsightedness, medically known as hyperopia, refers to vision that is good at a distance but not at close range. Farsightedness occurs when light entering the eye converges behind the retina. This can occur because the eyeball is shorter than normal, or the cornea has too little curvature, or a combination of both.
If you are mildly farsighted, 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, contacts, LASIK and photorefractive keratectomy (PRK). Your eye care provider at Downtown Vision Centre or Camas Vision Centre 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 too “long” as measured from front to back. This causes the light to converge in front of the retina, rather than directly on it.
Nearsightedness is diagnosed during routine eye exams and possible treatments include eyeglasses, contacts, acrylic corneal implants, LASIK, radial keratotomy (RK) and photorefractive keratotomy (PRK). Your eye care provider will suggest the best treatment option for you.
Presbyopia (Aging Eyes)
Aging eyes, medically known as presbyopia, is a condition in which the lens of the eye gradually loses its flexibility, making it harder to focus clearly on close objects such as printed words. Distance vision, on the other hand, is usually not affected.
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 progressives, bifocals and trifocals, single-vision reading glasses, multifocal contact lenses and monovision therapy.
