As with most things, spending as much as your budget allows will typically get you a long-lasting, hard-wearing product that delivers maximum performance while giving your vision the highest level of protection possible. For the quality assurance from fishing-specific brands such as Costa del Mar or Smith Optics, you’ll need to budget between $200 and $300, depending on the model you choose. However, it is possible to buy glasses that fit the essential criteria (polarization and 100 percent UVA and UVB protection) for as little as $50.
