- Do these glasses actually block blue light?
- Yes. The lenses are made to filter a portion of blue light from screens. Fifth & Ninth does not publish a specific filter percentage, so treat the effect as modest rather than clinical.
- Will the lenses look yellow?
- No. The lenses are clear, so colors stay close to normal. Strongly tinted blue light glasses cut more blue but change how everything looks.
- Can I wear these over contact lenses?
- Yes. They are non-prescription, so they work over contacts or on their own. If you need vision correction, order them in your prescription instead.
- How do I know the frame will fit?
- The rectangle is a medium-width women's frame with fixed nose pads. Check the temple and lens width against a pair you already own, since there is no nose-pad adjustment.
- Are they good for all-day computer work?
- They are light and clear enough for a full workday. If you get headaches or eye strain, take screen breaks too; glasses alone do not fix every cause.
- Where is the Fifth & Ninth Nita Rectangle Blue Light Blocking Glasses cheapest?
- At Urban Outfitters, for $45.00, as of our latest check.
