Questions? Answered.
How do glasses with no arms stay on?
The soft, flexible bridge gently grips the sides of your nose — a trusted design used by people who need reading power without full frames. Most forget they're wearing them.
How does the case attach to my phone?
Just peel the backing sticker and press the case flat onto the back of your phone — it sticks on and stays put through daily use, yet lifts off cleanly with no residue if you ever want to move it.
Will the case make my phone bulky?
No — it's about as thick as two credit cards and lighter than a house key. It works on bare phones and most phone cases, and wireless charging keeps working on most models.
What if I am in between strengths?
Caught in the middle? Start with the lower strength for a comfortable transition into clearer vision. And remember, you're backed by our 30-day guarantee.
Do the lenses scratch in the case?
No — the lenses ride in a protected channel and the scratch-resistant coating adds a second layer of protection.
