Common Vision Disorders

The most common vision disorders requiring corrective contact lenses include:

Hyperopia (Far Sightedness)

People with far sightedness have trouble seeing objects up close. Sewing, reading or using the computer may become difficult causing eye strain and headaches.

Hyperopia or far sightedness occurs as a result of an imperfection in the eye.  When light enters  the eye it focuses behind the retina instead of directly on it  resulting in blurring of the image.

Myopia (Short Sightedness)

People with short sightedness have trouble seeing objects at a distance. Driving a car may be difficult as the road signs can’t be seen clearly and children at the back of the class may have trouble seeing the chalk board at school.

Myopia occurs when the shape of the eyeball is slightly longer than normal. Light entering the eye focuses in front of the retina instead of directly onto it causing a blurred image.

Presbyopia (Age Related)

Presbyopia occurs in most people as a result of the aging process. The eyes gradually lose their capacity to see things at close range. This is why you may see people holding a book or newspaper at arms length as it becomes easier to read the further away it is.

Astigmatism

Astigmatism occurs when the cornea of the eye is oval shaped instead of round or when the lens of the eye is an irregular shape. The result is blurred vision as the light entering the eye cannot focus correctly onto the retina.

Hyperopia – Treatments for Farsightedness

Leave your comment

Is it hard for you to see things that are close up even though your distance vision is as acute as ever? Farsightedness is the result of an abnormality in the structure of your eyes that makes it difficult for them to focus on objects that are close to you. While farsightedness is often present from the time that you’re a child, it’s often not apparent until middle age when your eyes start losing their ability to adjust focus from near to far quickly and easily.

Farsightedness runs in families, although injuries or diseases in the eye may contribute to the condition in rare cases. It is most often diagnosed with a simple eye test, though headaches and eyestrain can signal problems with farsightedness in adults.

There are a number of options for correcting farsightedness, each with distinct advantages and disadvantages.

Eyeglasses

The most common treatment for farsightedness is eyeglasses with corrective lenses. They are the easiest and safest option for improving your vision if you have hyperopia. Glasses are readily available and can be fitted with precision and accuracy. Nearly everyone can wear eyeglasses, which can easily be replaced if the prescription needs changing.

On the other hand, eyeglasses aren’t an option for people in some professions such as fire-fighting. They can be expensive, uncomfortable and fragile.

Contact Lenses

Contact lenses have become more and more popular as the materials and styles available have improved. Today’s soft contact lenses are fitted with nearly as much precision as glasses, and provide better peripheral vision. In many cases the choice to wear contact lenses rather than glasses is a matter of appearance – you may simply  feel you look better without glasses.

On the flip side, contact lenses can be more expensive than glasses. If you’re not suited to wearing disposable or extended wear contact lenses, disinfecting and cleaning your contact lenses daily can be inconvenient.

Eye Surgery

Another option for correcting farsightedness is eye surgery. A surgeon skilled with a laser scalpel can reshape the cornea of the eye so that light focuses directly on the retina as it’s supposed to do rather than behind the retina, which distorts the vision. The results of surgery are variable, but when it is most successful, laser eye surgery can completely eliminate the need for glasses or contact lenses.
