Low price and low quality aren't the same thing -- here's what actually causes lens-related discomfort.
The price of a lens doesn't directly cause headaches -- inaccurate grinding, poor optical quality control, or an incorrect prescription entry does. A well-manufactured affordable lens ground accurately to your prescription performs the same optically as a far more expensive one with the same specifications.
The most common cause -- a typo or misread value at checkout, not the lens material or price.
An inaccurate pupillary distance misaligns the lens's optical center with your eye, causing subtle but real strain.
Rare with reputable retailers, but low-quality control can result in slight grinding inaccuracies.
Sometimes the glasses are fine, but the prescription itself no longer matches your current vision.
Compare your order confirmation against your written prescription, value by value, including PD.
Use our PD measurement tool if you're unsure, since this value isn't always included on prescriptions.
Some adjustment discomfort is normal for any new prescription -- see our guide on why new glasses feel off at first.
If discomfort continues beyond a week or two, reach out -- a manufacturing or entry error may need correcting.
