  • 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 –


    Prescription Type:


    Knowing your prescription type is pivotal in picking the right frame.

    • For people with myopia or hypermetropia, single vision lenses are the most suitable.
    • Bifocal and multifocal lenses are perfect for the ones suffering from presbyopia as these have two or more focal points respectively.
    • Plano lenses or zero power lenses suit the ones who do not have any eye power however, they may come with certain coatings to suit your lifestyle. E.g. computer glasses.

    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.


    lens material index range


    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.

    • Anti-scratch coating is a must for polycarbonate lenses in order to ensure its longevity. High index lenses also come with anti-scratch protective coatings for the same reason.
    • Anti-glare coating / anti-reflective coating is necessary for computer eyeglasses to keep away harmful blue light from entering the eyes.
    • In case you use sunglasses, your lenses may have polarized lenses & UV protective coating. In addition, they may come in various styles such as mirror, flash, gradient, tinted and photochromatic lenses.
