Bifocal contact lenses are a type of lens meant for people suffering from presbyopia. Presbyopia is an age-related condition where the eye experiences a gradual loss of its ability to focus on nearby objects. Presbyopia often appears in patients with a history of hyperopia but can also affect patients with myopia. For people with such problems, our eye doctors at Eye Doctors of Arizona can conduct a thorough eye exam to help determine your condition and see if you are fit for bifocal contact lenses.
Types of Bifocal Contact Lenses
Bifocal contact lenses differ in various ways to suit different vision needs. They mainly include:
Soft Contact Lenses
This lens is manufactured using flexible plastic that allows easy oxygen flow into your cornea. Some are also made using silicone-hydrogel.
Rigid Gas-Permeable Contact Lenses
They are more sturdy than soft contact lenses since they are made from durable materials. Additionally, they are highly resistant to the annoying deposit build-up, providing clear vision.
Extended Wear Contact Lenses
Extended-wear contact lenses are available in rigid gas-permeable and soft contact lenses. However, they last longer, and you can wear them for up to 30 days.
Types of Bifocal Contact Prescriptions
Bifocal contact lenses rest on the patient’s cornea and work similarly to glasses. The following are the two common types of bifocal contact lenses prescriptions:
They consist of two distinct areas: one at the bottom for presbyopia and one at the top. Segmented lenses are weighted and don’t move around, allowing you to see through the best part of the lens.
Concentric or Simultaneous
Instead of the upper and lower areas, simultaneous lenses have an outer and inner ring. The outer ring corrects one refractive error while the inner ring addresses the other.
