Timberland Sunglasses - Brown - Rectangle Frame

It means the lenses block all harmful ultraviolet radiation from the sun, preventing potential damage to your eyes.

Polarized lenses have a special filter that blocks intense reflected light (glare), making vision clearer and more comfortable, especially on water or snow.

Gradient lenses are darker at the top and lighter at the bottom, offering protection from overhead sun while allowing clearer vision for reading or looking down.

The polarized and gradient lenses are best suited for bright to moderately sunny conditions. Filter Category 3 offers good general sun protection. For very low light, they may be too dark.

The frames are made of acetate, a durable and flexible plastic known for its quality and ability to hold color.

While the frames are sturdy, fitting prescription lenses depends on the specific optical lab and the frame's shape and size. It is recommended to consult with an optician to check the possibility.

Always use a clean, soft microfiber cloth. Avoid abrasive materials like paper towels. For tougher smudges, a drop of lens cleaner or a slightly damp cloth can be used, followed by drying with the microfiber cloth.

As these are 'One Size', adjustments are limited. For minor looseness, a very slight bending of the temple arms inward might help, but this should be done with extreme care or by a professional. For tightness, consult an optician for potential professional adjustments if possible.

Use a soft microfiber cloth to gently clean the lenses. If smudges persist, slightly dampen the cloth with water or a lens-cleaning solution specifically designed for eyewear. Ensure the cloth is clean before use.

Acetate frames can sometimes cause discomfort if they are not the right fit for your face shape. Try adjusting the temple arms slightly if possible, or consider if the 'One Size' is suitable for your head size. Ensure they are not being worn for excessively long periods without a break if discomfort arises.
