Choosing the right lenses for your glasses can feel confusing, especially when prescriptions include different strengths for different distances. The two most common lens types: single vision lenses and varifocal lenses.
What Are Single Vision Lenses?
Single vision lenses are designed to one strength across the entire lens, making them the perfect choice for people who:
- Only need glasses for distance vision (like driving or watching TV).
- Only need glasses for close-up tasks (like reading, computer work, or hobbies).
Because they focus on a single working distance, many people choose to have separate pairs of single vision glasses, e.g. one for reading and another for distance.
What Are Varifocal Lenses?
Varifocal lenses are designed for people who need help with both distance and near vision. If your prescription includes a near add, then varifocals may be recommended.
Here’s how they work:
- The top of the lens is tailored for clear distance vision.
- The middle portion smoothly transitions into an intermediate prescription (ideal for computer use).
- The lower part of the lens provides the extra magnification needed for near vision (like reading).
This gradual progression means you can see clearly at all distances without constantly switching between different pairs of glasses, making varifocals a super convenient choice.
