Specialty Contact Lenses For Presbyopia

As we get older our vision starts to change. Between the ages of 40 and 50, almost all people develop presbyopia (age-related farsightedness), which makes nearby objects appear blurry.

Reading glasses used to be the only option for contact lens wearers with presbyopia who wanted to perform tasks that require good near vision such as reading a book or menu.

Nowadays, several specialty contact lenses offer patients with presbyopia clear near and distance vision for ultimate visual comfort and convenience.

Contact Lenses for the Farsighted

Monovision

This is a vision correction technique in which the contact lens in one eye corrects for distance vision and the other eye for near vision. Basically, each lens has a different prescription.

Scleral Lenses

Scleral contacts are large-diameter gas-permeable contact lenses that vault over the entire corneal surface and rest on the white part of the eye (sclera) instead of the cornea.

Scleral contacts can also be designed as multifocal contacts for presbyopic patients to correct both farsightedness and nearsightedness. When compared to regular multifocal lenses, scleral lenses are firmly positioned on the eye, offering substantially better stability and comfort.

Multifocal

Patients who wear multifocal contact lenses are able to see at all distances without sacrificing depth perception. Those who participate in outdoor activities, use the computer regularly or don’t like using reading glasses to view their smartphone, tablet, or newspaper might consider multifocal contact lenses.

There are two basic types of multifocal contact lenses: simultaneous vision design and segmented vision design.

1. Simultaneous vision design – Concentric rings of distant and near powers encircle a primary viewing zone in the lens’s center. The central viewing zone is typically used to view distant things, although there are also center-near designs. Under other circumstances, the dominant eye is fitted with a center-distance design, whereas the non-dominant eye is fitted with a center-near design. These multifocal contacts are similar to concentric multifocal lenses, but instead of discrete rings of distance and near power encircling the lens’s center, the multifocal lens power gradually changes from distance to near (or near to distant) from the lens’s center to the periphery. Aspheric multifocal contact lenses are similar to progressive eyeglass lenses in this way.

2. Segmented vision designs – Bifocal and trifocal eyeglass lenses have a similar design to segmented multifocal contact lenses. The upper and center zones of the lens feature a zone for distant vision, while the lower half of the lens has a zone for near vision. A noticeable line in the lenses separates the distant and near zones.

These contact lenses are made of rigid gas permeable (GP) contact lens material. These lenses have a smaller diameter than soft contact lenses and rest above the edge of the lower eyelid on a layer of tears. A segmented multifocal contact lens stays in place as your look shifts downward for reading or seeing close objects, allowing you to see through the lower, near-correction part of the lens.

Rigid gas-permeable (RGP)

RGP contact lenses are composed of rigid silicone polymers that allow oxygen to pass through the cornea. Unlike soft contact lenses, they hold their shape and can often provide clearer vision than soft lenses.

Orthokeratology

Orthokeratology, also called ‘ortho-k’ lenses, are lenses that are worn overnight to reshape the cornea. Ortho-k can be used to correct both eyes for distance vision and be used as monovision and multifocal vision.

Scleral Lenses for Athletes

Clear and comfortable vision is vital in sports—it can make a huge difference to optimizing your game-time performance. Fortunately, scleral lenses offer a way for athletes who need corrective eyewear to achieve their goals, even in contact sports like basketball, football and hockey.

Scleral lenses are custom-fit contact lenses for people with corneal irregularities, hard-to-fit eyes and severe dry eye syndrome, among other conditions. They provide comfort and offer sharp vision on and off the playing field.

Scleral lenses are extremely stable on the eye, as they vault over the cornea and rest on the sclera. Moreover, the reservoir of saline solution between the back surface of the lens and the front of the cornea ensures that the eye remains moist all day long. Furthermore, the lenses’ highly breathable gas permeable material ensures that plenty of oxygen reaches the front of the eye.

What Kind Of Athletes Wear Scleral Lenses?

Scleral lenses benefit athletes who find wearing traditional contact lenses challenging or impossible, and/or who have any of the following eye conditions:

  • Astigmatism
  • Dry eye syndrome
  • Presbyopia
  • Keratoconus
  • Post-refractive surgery (i.e. LASIK, PRK)
  • Giant papillary conjunctivitis (GPC)

Scleral Lenses for Athletes with Keratoconus

Keratoconus is an eye condition in which the cornea thins and weakens over time. This causes a cone-like bulge to develop and an irregular-shaped cornea. Keratoconus can result in increased sensitivity to light, distorted vision, slightly blurred vision and even significant vision loss. Professional athletes diagnosed with keratoconus often worry that the condition could end their career.

Scleral lenses are a long-term solution that helps athletes with keratoconus to continue to perform at their peak with amazing vision. Just ask professional athletes Brandon Williams from the Baltimore Ravens, Steph Curry from the Golden State Warriors, or Diamond DeShields from the Chicago Sky. These star athletes all wear scleral contact lenses and can now show off their true sporting prowess due to their sharp vision.

Do Scleral Lenses Work For All Sports?

When fitted correctly, the edges of these customized lenses fit comfortably under the eyelids, which prevents them from easily falling out. Moreover, because of their stability and extreme comfort, they offer an added advantage for athletes who engage in contact or extreme sports or those with rapid movements, such as in:

  • Basketball
  • Baseball
  • Football
  • Gymnastics
  • Hiking
  • Hockey
  • Rock Climbing
  • Soccer
  • Skiing
  • Tennis

However, scleral lenses are not advised for wrestling, karate, or boxing, other martial arts or any sports where facial injuries are common.

How Can Scleral Lenses Improve An Athlete’s Vision?

Athletes are often exposed to challenging environmental conditions, such as dust, chalk, sand and wind, all of which can lead to discomfort with soft contact lenses. As scleral lenses provide a seal over the eye’s surface, their eyes are much more protected from the elements. Because athletes have demanding visual needs, stable, clear, crisp vision is essential for optimal athletic performance.
