Having trouble focusing on near objects? Do you find yourself squinting to read a menu, or moving a book farther away from your face in order to see more clearly? You may be experiencing one of two very common vision conditions - hyperopia or presbyopia.

What is hyperopia?
Commonly referred to as farsightedness, hyperopia is a condition in which the eye is underpowered. Objects in the distance are viewed clearly; however objects close-up appear blurry. Symptoms include squinting, eyestrain, and near objects appearing blurry. Occasionally, headaches may occur when focusing on near objects (during activities such as reading or sewing) for an extended period of time. Hyperopia is usually present at birth and tends to run in families.
 
What is presbyopia?
Presbyopia is a natural part of aging in which the lenses in the eye thicken and lose their elasticity, and the muscles surrounding the lens weaken. This causes the worsening of vision and the decreasing of focus, especially on near objects. Symptoms include blurred vision (which can worsen in dim light or when you are fatigued), eyestrain and headaches. The condition usually starts around age 40 and progresses through age 60.

I think I may have hyperopia or presbyopia. What do I do?
Contact your eye care professional, who can perform a comprehensive eye exam, which will help detect either condition. Contact lenses or glasses can correct both hyperopia and presbyopia.

Spherical contact lenses or glasses can correct for hyperopia - correction requires a "plus" lens containing additional optical power to permit sharp vision of near objects. Multifocal contact lenses or glasses can correct for presbyopia - multifocal contacts focus light from both near, intermediate and far distances to the back of the eye, creating the clearest possible image.

Just about everyone will have a need for vision correction at some point during their lives - especially later in life, when reading small type becomes more difficult. By understanding the most common vision conditions, you’ll know what vision condition you have and how this condition can be corrected with contact lenses.

As with any issue involving your vision, an eye care professional is the best person to answer any questions you may have. Furthermore, only he or she will be able to provide you with an accurate diagnosis of your specific vision condition.

Did you know?  The human eye has the sharpest vision when light rays passing through the various structures of the eye meet at a sharp focal point on the foveal area of the retina.  Although the cornea and lens of the eye may be perfectly round, if light rays are focused before they reach the retina (a condition known as Myopia or Nearsightedness), distance vision will not be clear.   If light rays are focused behind the plane of the retina (a condition known as Hyperopia or Farsightedness) vision may or may not be clear depending on the amount of hyperopia and the amount of someone’s focusing ability.  Although a hyperopic person may see clearly both at distance and near, if too much focusing effort is needed, discomfort, headaches, etc. may occur.  If not enough focusing ability is available, vision will not be clear up close or at both up close and distance. 

Distortion of vision can also occur when the curvature of the cornea is football-shaped (a condition known as Astigmatism) rather than uniformly round as light rays will not be focused at a sharp focal point.
