Lenses disperse light to reduce glare and protect bulbs from damage. Cut to size using a band saw or shears.

Solid lenses keep bulbs hidden and distribute light evenly. Lenses with a prismatic or cracked ice pattern distribute light better than smooth lenses.

Acrylic lenses won't turn yellow over time. Polycarbonate lenses are more impact-resistant than acrylic lenses, but they may yellow over time.
