You may need some time to get adjusted to your bifocal lenses. Most wearers tend to get used to them after 1-2 weeks. However, it can take longer than that depending on your vision issues and/or needs. Eye care specialists recommend no-line bifocals/progressives for folks who do not like the changes in vision. MarvelOptics.com is always here to answer all your bifocal and eyewear-related questions or concerns.
