Single Vision vs Varifocal Lenses: What's the Difference?
Single Vision vs Varifocal Lenses: What's the Difference?
If you're buying new glasses, you may come across terms like single vision and varifocal lenses. While they both improve vision, they're designed for different needs.
Understanding the difference can help you choose the right lenses and avoid confusion when ordering your next pair of glasses.
What Are Single Vision Lenses?
Single vision lenses have one prescription across the entire lens.
They're designed to correct one type of vision, such as:
• Distance vision
• Reading
• Computer use
Most people who are short-sighted or long-sighted wear single vision lenses.
What Are Varifocal Lenses?
Varifocal lenses contain multiple prescriptions within one lens.
They allow you to see clearly at different distances without changing glasses.
Typically, the top of the lens is used for distance vision, while the lower part helps with reading and close work.
Who Needs Single Vision Lenses?
Single vision lenses are suitable for people who only need one prescription.
They are commonly worn by:
• Children
• Young adults
• People who only require glasses for driving
• People who only need reading glasses
Who Needs Varifocal Lenses?
Varifocal lenses are generally recommended for adults who need help with both distance and reading vision.
Many people begin needing reading correction in their 40s or 50s due to age-related changes in focusing.
Are Varifocals Difficult to Get Used To?
Some people adapt immediately, while others need a short adjustment period.
Moving your eyes naturally through different areas of the lens usually becomes easier after a few days.
Your optometrist can advise if varifocals are suitable for your prescription.
Can You Order Both Online?
Many online retailers offer both single vision and varifocal lenses.
It's important to choose the correct lens type when placing your order and ensure your prescription is entered accurately.
Which Option Is Right for You?
The best choice depends entirely on your prescription and how you use your glasses.
If you only need one prescription, single vision lenses are usually the simplest option.
If you need clear vision at multiple distances, varifocals may provide greater convenience by reducing the need to swap between different pairs of glasses.
If you're unsure, check your prescription or ask your optometrist before ordering.
