Around the age of 40, many patients will start experiencing blurred vision when reading or trouble seeing any objects up close. If you’re experiencing similar symptoms, you are not alone. Presbyopia is all part of the normal aging process, and very common among adults 40 and older. The good news is that you don’t have to resort to eyeglasses just yet. Our optometry team at The Eye Doctors offer multifocal contact lenses for Havertown and Delaware County residents.
What are Multifocal Contact Lenses?
Multifocal contact lenses (also known as “progressive contact lenses”) have multiple prescriptions in each lens. There is typically a prescription for very close objects: one prescription for normal objects viewed at a distance, and then prescriptions for intermediate distances.
These lenses allow significantly more oxygen to reach the cornea than conventional soft lenses for greater comfort. They are available in both soft and rigid gas permeable (RGP or GP) lens materials and both daily wear and extended wear.
What is Presbyopia?
Presbyopia is very common with age where near vision becomes blurred, making it hard to focus while doing things like reading, using a cell phone, or working on the computer.
Along with astigmatism, nearsightedness (myopia) and farsightedness (hyperopia), presbyopia is 1 of the 4 common imperfections of the eye called refractive errors.
Who Can Benefit from Multifocal Contact Lenses?
The most common reason patients use multifocal lenses is for presbyopia, a condition in which you may have trouble seeing both close-up and far away. With progressive lenses, you can look up to see clearly across the room and in the distance. You also can look ahead to view your computer in the intermediate zone and look downward to read and do fine work comfortably through the near zone of the lenses.
Moreover, multifocal contacts can also correct astigmatism by using a toric lens design.
Multifocal Contact Lenses at The Eye Doctors
Depending on your prescription and your daily needs, our optometrist at The Eye Doctors, Dr. Toyzer, may recommend either soft or rigid gas permeable lenses.
Several different kinds of multifocal contacts are available, each of which has its own particular advantages. These include:
- Concentric– These popular multifocals alternate the different visual fields in concentric rings around the pupil.
- Aspheric – This type of “blended” multifocal puts the near vision in the center of the pupil and progresses outward toward distance vision near the edges.
- Translating– This type of lens mimics traditional bifocals, with a near vision field at the bottom clearly delineated from the distance field above. This type of lens must be weighted at the bottom or specially shaped to keep it from moving around on the eye.
Ultimately, you have to try these solutions out to know which one works for you; you may even decide to try two different monovision lenses that put the distance field in one eye and the near field in the other.
