What is poly lens?

Poly lens, also known as polycarbonate lens, is a type of lens used in eyeglasses, sunglasses, and safety eyewear. It is made from a durable and lightweight optical-grade plastic called polycarbonate.

Here are some key features and benefits of poly lenses:

1. Impact resistant: Poly lenses are highly impact resistant and provide protection against physical injuries. Due to their durable nature, they are commonly used in sports eyewear and safety glasses.

2. Lightweight: Compared to other lens materials like glass or regular plastic, poly lenses are significantly lighter. This makes them more comfortable to wear and reduces the strain on the nose and ears.

3. Thin and aesthetic: Poly lenses can be made thin and flat, providing a sleek appearance for eyeglasses. They are suitable for people who require high prescription lenses as they can reduce the thickness and weight of the overall glasses.

4. UV protection: Poly lenses inherently come with built-in UV protection. They block a significant amount of ultraviolet (UV) rays, which helps in protecting the eyes from potential damage caused by sun exposure.

5. Scratch resistant: Poly lenses have a hard coating that provides increased scratch resistance, making them more durable and long-lasting. However, it's important to note that they are not entirely scratch-proof and proper care should be taken to avoid damaging the lenses.

6. Prescription compatibility: Poly lenses can be easily customized for different prescriptions, allowing people with nearsightedness, farsightedness, astigmatism, and other vision issues to use them as corrective lenses.

Overall, poly lenses combine durability, lightness, and UV protection, making them a popular choice for various eyewear applications. However, they may be more prone to optical distortions and are not suitable for all vision correction needs, thus it's always recommended to consult an optometrist or eyecare professional for the best lens choice based on individual requirements.
