Vision Problems

Astigmatism

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.

Hyperopia (Farsightedness)

Farsightedness, medically known as hyperopia or hypermetropia, refers to vision that is good at a distance but may not be as clear at close range. Generally the complaint of a hyperopic patient isn’t so much blurriness as it is headaches, tiredness or poor tracking, especially as the day goes on.

Myopia (Nearsightedness)

Nearsightedness, medically known as myopia, refers to vision that is good at close range but not at distance. Myopes generally do extremely well with corrective lenses as the correction is more obvious as distance becomes clear upon correction.

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. This usually becomes apparent when your arms aren’t long enough to help you read. 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.
