If you normally wear multifocal glasses, you can also wear contact lenses. Multifocal contact lenses can help you easily switch between prescriptions, from far to near and in-between. They are great for reading a menu or playing sports, without having to carry an extra pair of glasses.

At Village Eye Centre in , Downtown Edmonton, and Sherwood Park we offer the different types of multifocal lenses. Learn more about multifocal lenses and how they work.

What Are Multifocal Contact Lenses?

Multifocal contact lenses are made with different lens powers, targeting vision at varying distances. These contact lenses have multiple prescriptions in one lens, making it easier to switch between seeing close-up, in-between, and far away.

What Are The Different Types Of Multifocal Contacts?

Multifocal contact lenses come in both soft lens and gas permeable lens materials. There are two types of multifocal contact lenses. Alternating vision lenses and simultaneous vision lenses.

Alternating Vision lenses

Alternating vision lenses enable you to go between two different powers as your pupil moves down and up. You’ll have to switch between distance and near viewing powers. There is usually a line in the lens which determines which part of the lens you use.

Simultaneous vision lenses

Simultaneous vision lenses force your eyes to look through distance and near powers at the same time. You’ll have to learn how to use the correct powers depending on what you are looking at. The more you use the lenses, the more your eyes get used to the lenses. Your brain will need to learn how to adjust what you see with these types of lenses.

Simultaneous vision lenses come in either aspheric or concentric ring designs.

Aspheric simultaneous vision lenses blend the different powers together across the lens, so there is a progressive change from far to near powers.

Concentric ring simultaneous vision lenses consist of numerous rings with different powers. The rings alternate between far and near vision powers.

If you are considering multifocal lenses over multifocal glasses, contact Dr. James Evans to learn more about which type would best suit your eyes.

Frequently Asked Questions with Dr. James Evans

Q: Can you request lenses made from glass? Is glass still used for lenses?

  • A: Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.

Q: Can a coating be added to eyeglasses to protect them from further scratches?

  • A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.
