LEECH's Street Earth is the best-selling model. It was "Street" that literally put Leech on the map within the fishing community. Not only does the signature tweak of the classic Wayfarer frame appeal to the market, after a long and extensive process we have also found a fit that is a good fit for 90% of everyone who tries this model. Street is available in different color combinations, with matching Premium + lenses. Copper lenses help enhance contrast and improve depth of field for objects like fish against the aqua-colored backgrounds. We recommend that you wear copper lenses as it gives them good definition and prevents eye strain. In addition, it is very suitable in the morning and in the evening and it becomes much easier to see the fish. The advantage of Premium + lenses - sharper vision.

Anti-reflective coating, also known as AR coating or anti-reflective coating, improves both your vision through your lenses and the appearance of your glasses. The visual benefits of anti-reflective coated lenses include sharper vision. AR eliminates glare from sunlight reflecting into your eyes from the back of tinted lenses when the sun is behind you. Imagine how much better you will see in the rain with a pair of hydrophobic lenses. This coating binds the molecules of the lens together, leaving no room for water to penetrate and causing permanent water damage. This reduces the need to clean the lens as often as other lenses, while making the cleaning process effortless. See more clearly with sunglasses with a hydrophobic coating and allow water to slide off the lens surface with ease.
