Lens Materials

GLASS LENSES

For years, glass was the only lens material available and glass still recommended as superior optics. Even though glass is the most scratch-resistant material, the primary disadvantage of glass is its weight, usually twice that of hard resin. Glass lenses are heat or chemically tempered to increase impact resistance but can be dangerous if they break. We are very selective in that case as to who can wear glass lenses. Our Opticians do not recommend glass for children, as they can be a safety hazard.

PLASTIC LENSES

Conventional Plastic lenses are half the weight of glass lenses and can be tinted to almost any color and density. Plastic lenses are more easily scratched than glass but can have an optional scratch protection applied. This coating give more impact of resistant than glass.

POLYCARBONATE LENSES

Polycarbonate lenses are the most impact resistant lenses available at present and are always the lens of choice for young people and active patients. Polycarbonate lenses are with high index and usually provide the lightest, most comfortable lenses. They absorb all detrimental UV radiance and light and can be made of ultra-thin because of their unique strength. Our Poly Carbonate lenses provide clear vision. These lenses are lighter and thinner lenses than regular lenses and safe to use for its high impact resistant.

MR8

Unbreakable or Break- Resistant Lenses are made of superior impact-resistant substance MR-8 (Mitsui Resin). It has very high tensile strength, making it more durable during bending and curving processes. In addition, it has very high static load resistance, which enables it to carry high pressure without any damage.

 BLUE CUT

All digital devices – mobile phones, laptops, tablets, television etc emanate blue light. Long-drawn-out exposure to blue light is progressively more causing retinal damage. You cannot stay away from digital devices even for a minute. When you are at work, your eyes are at work too because when you are in relaxation means chatting on Viber, Whatsapp, checking Facebook or playing a game. Therefore, your eyes do not have any break from work. Now you can protect your precious eyes from blue light by simply using our revolutionary Blue Cut lenses. Blue Cut Lenses have a special coating, which reflects blue light from digital devices and prevents it from passing through the lenses. Our blue cut lenses offer 100% UV protection that reduce eyestrain and protect eyes from blue rays. Also, prevent Macular Degeneration.

Lens Type

SINGLE VISION LENSES

Single vision lenses are available in several different lens materials, such as polycarbonate, plastic or high-index. With ordinary plastic lenses, a strong prescription can result in thicker, heavier glasses. In contrast, high-index lens material will reduce thickness for greater comfort and a better appearance.

PROGRESSIVE LENSES

Progressive lenses give you two vision powers (Distance and Near Power) in one seamless lens for a more natural and flattering way to see your world. If you need more than one lens strength to read, do computer work or drive, progressives let you see clearly at any distance with one pair of glasses. You simply adjust your head position to see three ranges of distance. Bring your head up to see far away; look straight ahead for mid-range vision, and point your nose down to read or do close-up work, like texting. Our progressive lenses provide natural vision for all distances and seamless lens without any visible lines. This lens is comfortable for driving and viewing digital devices.

BIFOCAL LENSES

Bifocals are eyeglasses with two distinct optical powers with mark (D Lens and Moon Lens). Bifocal lenses are generally prescribed to people with presbyopia who also require a correction for myopia, hyperopia, and/or astigmatism.

Index Lens

There several variety of thin, lightweight high index eyeglass lenses, which is based on how competently the lens bend the light. ‘Light bending’ capacity of lenses is measured based on the “index of refraction“. This refractive index is the ratio of the speed of light when it travels through air to the speed of light when it passes through the lens substance. Therefore, to bend the light more efficiently, eyeglass lenses need a higher index of refraction and higher index are thinner, lightweight than the lenses of same power made of same materials of lower index.

Usually plastic lenses have a refractive index of approximately 1.50 and for glass this index 1.52. Now, a wide range of refractive indices is available in plastic lenses. The range of index is from 1.53 to 1.74. We offer 1.56 refractive indices for our all eyeglass lenses.

Coating

ANTI- REFLECTIVE

Anti-reflective coating can lessen eyestrain caused from glare, reflections, and the “circle of light” you see around lights at night. It helps protect your lenses from scratches and splotches, and can keep away from dust and water. This coating makes your vision sharper and your eyes appear clearer behind your lenses. Anti-reflective coatings reduce the unwanted reflection and improve the vision.

BLUE LIGHT COATING

Blue light Coating is a next-generation lens coating that combats digital eyestrain by reducing your exposure to blue light from smartphones, tablets, computer screens, televisions, energy-efficient lighting, and the sun. This attractive, near-clear coating also optimizes visual performance, improves visual comfort, enhances your appearance, and extends the life of your lenses.

PHOTOCHROMIC LENSES

Photochromic lenses are also known as “light-adaptive lenses” and “variable tint lenses”. These lenses are eyeglass lenses that have clear vision for all light conditions. This lens also provide easier vision in both conditions (indoor and sunlight). In general, Photochromic lenses darken considerably in response to UV light in less than one minute, and continue to darken a little more over the next fifteen minutes. The lenses begin to clear in the absence of UV light, and will be noticeably lighter within two minutes, mostly clear within five minutes, and fully back to their non-exposed state in about fifteen minutes.

 HYDROPHOBIC COATING

Hydrophobic Coating treatment weakens surface tension to facilitate run-off of water drops from the lens surface. It lessens visual deformation arising when wearing glasses or sunglasses around water or in the rain. It also refuses to go along with stains and resists grease and fingerprints, so cleaning your lenses are quicker and easier.

 

SCRATCH- RESISTANT COATING (SRC)

All lens materials (plastic, polycarbonate, MR8, blue cut and high index plastics) have a relatively soft and squashy surface. These lens materials require a coating to apply in both sides of the lens. Glass lenses do not require SRC. Because of its natural hardness, glass is even more scratch-resistant than most lightweight lenses with SRC applied. This coating helps to prevent minor scratches on lens materials and makes the lens more durable and long lasting.
