Bifocal & Multifocal Contact Lenses
As we age, it’s natural that our eyesight declines. To keep up with good vision, we need the help of some different eye glass progression.
Presbyopia and Contact Lenses
Are you familiar with the people in their 40’s who are holding their reading material away from their eyes just to read it? Reading requires more effort for people who already have Presbyopia. This is the condition that, usually, people in their 40s or older experience. In other words, this is a condition that normally occurs as people get older. But experts have found a solution; Progressive lenses or eyeglasses!
As we age, these glasses allow for consistent and clear vision from all sides so you no longer need to adjust the distance of the object or material you’re reading. Doctors fit these eyeglasses to the need of each individual’s eye, thus a prescription is needed. In fact, this type of eyeglasses comes with varieties that suit your prescription, and lenses that are in Rigid Glass Permissible (RGP).
Bifocal or Multifocal Lenses: What’s the Difference?
Two common types of progressive eyeglasses and lenses are bifocal and multifocal. We must keep in mind, however, that not all who age will be a match for these. It is imperative that you see a doctor and get a proper prescription.
Bifocal Lenses is simply what the term suggests. This has two lenses that form it; one for sighting near objects and the other one is for those at far.This lens ensures that when viewing things either far or near, the vision is clear. However, the downside of this type is that the object in between may not be clear.
Multifocal Lenses, on the other hand, fills in the gap of bifocal lenses. If the first one cannot assure good vision in between far and near objects, multifocal lenses offer more zones for your eyes making all sides clearer. Also known as non-bifocal lenses, this contact lens has the power of combined bifocal and trifocal versions allowing users to easily adjust their focus.
Simultaneous Vision Lenses
Due to its wide variety of benefits, multifocal contact lenses already have subtypes which our experts determine in order for your unique eye needs to be met with safety and precision. The first type is the simultaneous vision lenses.
These lenses provide wearers simultaneous far and close-up vision without necessitating contact lens movement. The brain dismisses the other image and chooses one based on proximity or distance. The close and distance zones of correction are positioned in front of the pupil (Gurnani, Kaur, 2022).

Alternating Vision lenses
The second type of multifocal lenses are made up with rigid gas permission so you can be assured of its safety. These GP multifocal lenses imitate bifocal eyeglass lenses in how they are made. The distance power is situated in the top section of the lens, while the near power is located in the bottom portion of the lens. Your eye is gazing via the faraway portion of the lens when you stare straight ahead. While your pupil switches into the near zone of the lens for reading when you gaze down, your lower lid strengthens the lens.
Monovision Lenses: One of the Best Alternatives for Presbyopia
If you take an eye test, it is possible that a dominant eye of yours will have a different prescription than the other one.This is where a modified monovision lens would be your best option. It is actually quite a common condition where one of their eyes needs multifocal lenses while the other needs single vision.
A technique for correcting presbyopia is monovision contact lenses. This particular type of treatment is based on the placement of two separate contact lenses, one for treating near vision and the other for correcting far vision. Your dominant eye should be taken into consideration while deciding which eye will require which lens. The dominant eye, that additionally records distant sights, tends to deliver the information that the brain chooses to focus on more (VisionDirect).
