WHAT'S THE DIFFERENCE BETWEEN NEAR AND FAR SIGHTED?

Nearsighted

Individuals who have this condition, also called myopia, are only able to focus on nearby objects. Objects in the distance are unfocused, requiring correction to be able to see them. Myopia is considered to be an inherited condition.

This condition is the result of the eyeball being longer than normal, causing the light to fall short of reaching the retina. Young, school aged children or teenagers will often develop this issue due to the rapid growth that’s undergone during these formative years. It can require many changes to prescription lenses as the eye develops.

Farsighted

When a person states they suffer from farsighted, or hyperopia, they are able to see objects that are at a distance better than those that are up close. Hyperopia is an inherited trait, but can also developed over time.

In farsighted people, their eyeball is shorter than normal length, which causes the light to land behind the retina. Another possible reason is a weak or diminished focusing ability. Individuals with severe farsighted vision can also have difficulty with near vision.  

Farsightedness is often present from birth. Children are often able to tolerate and function well without visual correction from farsighted vision. In many cases these children are able to outgrow this visual issue.

Correction

Both nearsighted and farsighted individuals can benefit from the use of corrective lenses, either as glasses or contacts. For those interested in a more permanent solution, there are surgical procedures. Myopia has shown great response to PRK and LASIK procedures. Hyperopia is routinely addressed with LASIK surgery.

Both LASIK and PRK are permanent solutions to these common visual acuity complaints. These surgeries provide lasting results by physically altering the shape of the cornea.
