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 Dr McMunn and the staff at Advanced Eyecare.
Astigmatism is an irregular curvature of the eye, which results in blurred or distorted vision. Other symptoms of astigmatism include squinting, eye strain, doubled vision, headaches and eye fatigue.
In reality, most people have some degree of astigmatism. In minor cases, treatment may not be required but is certainly beneficial, especially for driving, board work at school, and computer work. Moderate to severe astigmatism can be treated with corrective eyewear, contact lenses, and LASIK surgery.
Farsightedness, medically known as hyperopia, refers to vision that is good at a distance but not at close range. Farsightedness occurs when the eyeball is shorter than normal, or when the cornea is too flat (has too little curvature). This reduces the distance between the cornea and retina, causing light to converge behind the retina, rather than on it.
If you are mildly farsighted, Dr McMunn may not recommend corrective treatment at all. However, if you are moderately or severely hyperopic, you may have several treatment options available, including eyeglasses, contact lenses, LASIK and photorefractive keratectomy (PRK). Dr McMunn will help you determine the best treatment option for you.

Nearsightedness, also 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. This causes light to focus in front of the retina instead of on it.
Nearsightedness is diagnosed during routine eye exams and possible treatments include eyeglasses, contact lenses, corneal refractive therapy, Intacs (corneal implants), LASIK, radial keratotomy (RK) and photorefractive keratotomy (PRK). Dr McMunn will suggest the best treatment option for you.

Presbyopia (Aging Eyes)
Presbyopia is a condition in which the lens of the eye gradually loses its flexibility with age, making it harder to focus clearly on close objects such as printed words and computer screens. Distance vision is usually not affected.
This loss of near focus 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.
