What are the best lens for sight fishing?

Sight Fishing may sound easy but in reality, most often it can be difficult. To be able to sight fish comfortably your eyes need the right equipment. Polarized sunglasses are used to reduce the glare from water surfaces and will reduce the stress on your eyes and help you see more clearly.

Polarized sunglasses only allow vertically orientated light through, blocking horizontally orientated light. This helps get rid f glare almost completely.

This will benefit your sight fishing as the fish will be spotted a lot more easily. Wether on a river, on the flats, or on a lake. Polarized sunglasses will easily help you read a body of water. Another important thing to look at is the UV protection that the glasses offer.


"Increased contrast is very helpful for fishing flats, shallow trout streams and lakeshores. Choose a brown or copper colored lens for normal conditions on the flats, and an amber or yellow lens for cloudy, overcast conditions."

When it comes to lens material choice I have listed the best lens types and why. these are the main choices of lens for fishing:


Polycarbonate lenses are highly resistant to impact, won't shatter, and are 10 times stronger than glass or standard plastic, making them ideal for children, safety lenses, and physical activity. Lightweight and thinner than glass lenses, polycarbonate is more comfortable to wear for long periods of time.


TAC (Tri Acetate Cellulose) polarized lenses offer superior visual and polarization clarity. They are hard coated to resist scratching and block out 100% of all harmful UV rays up to 400 nanometers, and are also lightweight and highly impact resistant.


Glass is much more scratch resistant than plastic, making the glasses last longer. ... Plastic lenses are less reflective than glass lenses, making them clearer and less prone to glare. Glass lenses generally have a higher index than plastic lenses, making them slightly thinner and more attractive looking.

Glass will always provide the best optical experience as glass refracts light much more efficiently than plastic. It’s the most scratch resistant lens material and blocks UV light. However, glass lenses are heavy (typically sliding down your nose) and can be dangerous: glass lenses are prone to cracking, can shatter with impact or if dropped on a hard surface such as concrete. There are also a limited range of colours available made from glass; for all these reasons glass is not used for sports eyewear.

Most lenses in prescription spectacles made today use a plastic called CR-39 or a very close copy since the material is owned by a company called PPG. Half as heavy as glass, and far less likely to shatter, the optical quality is nearly as good as glass. Plastic is much lighter than glass, making it more comfortable to wear all day and plastic lenses come in many more colours and larger sizes. It is also much less expensive to use than glass. Hence, since the creation of the plastic lens, it’s become the “default” material for opticians and glass lenses are now much rarer than plastic when it comes to prescription glasses. However, it’s important to recognise that plastic can still shatter and does not provide a high level of impact protection, so it should not be used for most active or shooting sports.


The Green Mirror lens is best suited for super bright, sunny days where there are high contrast lighting conditions. It should be mentioned that the mirrored lenses have the added benefit of reducing glare

The Copper lens is the most versatile lens and performs well on both sunny and cloudy days and is an excellent lens for sight fishing. The Copper tinted Cat 3 UV 400 polarized lenses offer 23% light transmittance and 77% light absorption.

The lenses improve depth perception and increase the distinction of contours. Great on sunny and overcast days with increased contrast.  This is the best color combo for sight fishing and general all-round scenarios except for overcast dark days.
