Single vision contact lenses correct vision at one distance, typically for nearsightedness (myopia) or farsightedness (hyperopia). They are the most common type of prescription contact lens and use one consistent power across the entire lens. If you also need help for close-up reading, your eye doctor may recommend reading glasses over contacts or a different lens type such as multifocal contacts.
What to Check:
- Look for PWR or SPH on your contact lens prescription, since this single number is the main correction for single vision lenses.
- If you have astigmatism, you may need a toric single vision lens, which also includes CYL and AXIS values.
- Check BC (base curve) and DIA (diameter), because fit measurements can vary by brand and affect comfort and stability.
- Choose a wear schedule that matches your routine, such as daily disposable or reusable lenses, and follow the replacement and cleaning instructions.
- If you have new headaches, blurry vision, pain, or persistent dryness, stop wearing the lenses and ask your eye care professional to recheck fit or prescription.
Single vision contacts provide one consistent prescription power for everyday distance or near correction, with lens fit and wear schedule tailored to your eyes and lifestyle.
