You've decided FL-41 is right for you. Now comes the next question: which frames? With several styles available, choosing the right pair comes down to three things — fit, coverage, and how you plan to wear them.
Start with how you'll wear them
FL-41 glasses are designed for all-day indoor wear, but your specific environment matters when choosing a frame style.
- Office or desk work — You want a frame that sits comfortably for hours and covers enough of your visual field to block peripheral light from overhead fluorescents. Rectangle and aviator styles work well here.
- On the go — If you're moving between environments (office, supermarket, driving), a versatile frame with good coverage and a secure fit is key. Aviators and cat-eye styles offer a balance of coverage and wearability.
- Wearing over prescription glasses — If you already wear glasses, an overfit style is designed to sit comfortably over your existing frames without pressure or slippage.
Understanding frame styles
Aviator
Aviators offer broad lens coverage and a slightly downward-angled lens shape that protects against light coming from above — particularly useful under overhead fluorescent lighting. The teardrop shape provides generous coverage across the visual field. A strong all-day option for most environments.
Cat-Eye
Cat-eye frames offer good upper-field coverage with an upswept shape that suits a range of face shapes. A practical choice for everyday wear that balances coverage with a refined aesthetic.
Rectangle
Rectangle frames provide consistent, even coverage across the visual field. Clean and understated, they work well in professional environments and pair easily with most face shapes.
Overfit
Overfit frames are designed to wear directly over prescription glasses. They provide full FL-41 coverage without requiring a separate prescription lens — making them the most practical option for anyone who already wears corrective eyewear. Available in multiple sizes to fit different frame widths.
Getting the right fit
A well-fitting frame should:
- Sit comfortably on the bridge of your nose without sliding
- Cover your eyes fully, including the upper and side fields where overhead light enters
- Feel secure enough for all-day wear without pressure on your temples
For overfit styles, measure the width of your existing glasses at the widest point and compare to the overfit dimensions listed on each product page.
Face shape as a guide
While personal preference always wins, these general guidelines can help narrow your choice:
- Oval face — Most frame shapes work well; aviators and rectangles are particularly flattering
- Round face — Rectangle and angular frames add definition
- Square face — Cat-eye and aviator shapes soften strong jaw lines
- Heart face — Cat-eye and aviator styles balance a wider forehead
A note on lens coverage
For migraine and photophobia relief, lens coverage matters. Frames that sit close to the face and cover a wider visual field provide more consistent filtration — particularly important in environments with overhead or peripheral light sources. If your migraines are severe or your photophobia is significant, prioritize coverage over style when in doubt.
