When it comes to lenses, many of us are often confused on what to buy and what’s right for the eyes. A person’s lifestyle and prescription type are the most important elements while choosing the right frame lens. However, there are certain other factors like lens material and lens coating or treatment which ensure a perfect vision. Here’s a quick guide to make you feel like a pro while choosing the right lenses for your eyewear –
Knowing your prescription type is pivotal in picking the right frame.
Lens Material & Index Range:
Earlier lenses were crafted with heavy and thick glass material. However, seeing the potential harm glass lenses can do to the eyes if they break, these were replaced by lightweight plastic. Today, the highly used optic lens materials apart from plastic (CR-39) are polycarbonate, Trivex and high index plastics.
Usually, these are separated with their refractive index properties. Ranging from index 1.49 - which is a thick and heavier lens as compared to high index 1.61 & 1.74 lenses which are extremely thin and the most fashionable. People with high eye power range are recommended to go for high-index lenses for their slim and sleek features and light-weight profile.
Lens Coatings & Treatments:
Treating your lenses with protective coatings is highly necessary in today’s time as usually all lens materials have softer surface which needs extra protection from everyday wear and tear.
