Our take on the Costa Prescription Mariana Trench 500 Eyesize Custom Lenses

The Costa Mariana Trench 500 is a rectangular full-frame sunglass built from acetate in a speckled black tortoise pattern, sold here with prescription lenses cut to your eyesize. Costa is known for fishing and water-sports eyewear, and this frame carries that heritage in a dressier, everyday shape than the brand's sport wraps. It suits adults who want a wide rectangular look with their own prescription rather than a plano lens. Against Costa's sport frames it gives up wrap coverage and venting, but it reads more like a lifestyle sunglass and takes custom lens options.

Best forAdults who want a rectangular everyday sunglass in prescriptionAnglers and boaters who prefer a classic frame over a wrapShoppers with a wide face needing a larger eyesizeBuyers who want a single pair for driving and daily wear
Pros
  • Full acetate frame with a substantial rectangular shape
  • Speckled tortoise finish hides scratches better than plain black
  • Custom prescription lenses cut to your eyesize
  • Costa's water-sports lens heritage behind the brand
  • Classic look that works off the water as well as on it
Cons
  • No wrap coverage or side shields, so less glare and wind protection than Costa sport frames
  • Acetate is heavier than the brand's nylon sport frames
  • Rectangular shape and large eyesize won't suit narrow faces
  • Prescription lenses add cost and lead time over stock plano versions

Questions and answers

Is the Mariana Trench 500 good for fishing?
It works for casual fishing and boating, but it is a lifestyle rectangle, not a wrap. Costa's sport frames block more side glare and wind, so serious anglers often pick those instead.
How does it compare with Costa's sport frames?
The Mariana Trench 500 trades wrap coverage and light weight for a dressier acetate rectangle. It is better for driving and everyday wear, less good in spray and bright side light.
Can I get these in my prescription?
Yes, this version is sold with custom prescription lenses cut to your eyesize. You will need a current prescription, and the lenses take longer to arrive than stock plano lenses.
What is the 500 eyesize?
The 500 refers to the frame's eyesize, a larger fit in Costa's range. It suits wider faces; if you normally wear narrow frames, try it on or check the measurements first.
What comes in the box?
Expect the frame with your prescription lenses fitted, plus Costa's standard case and cleaning cloth. Confirm the exact contents with the seller before ordering.
Is acetate durable for daily wear?
Acetate holds its shape and color well and the speckled finish hides small scratches. It is heavier than nylon sport frames, so long days on the water may feel less light.
