High Index & Standard Index Lenses

High Index & Standard Index Lenses

What are high index lenses?

In layman's terms, high-index lenses are thinner and lighter than standard lenses, even when they have a higher prescription. It is a lens with higher refraction properties, allowing it to bend light and correct vision. Individuals who have a refractive error such as nearsightedness, farsightedness, or astigmatism must wear strong prescription lenses because their vision deteriorates over time. Because nearsightedness is one of the most common eye conditions, the vast majority of glasses are nearsighted. Because you are nearsighted, you must wear glasses that are thin in the centre and thicker around the edges.

If you have average or higher myopia, you will need to wear lenses that are as thick as a brick on your eyes. Which feels heavy, and the weight of those lenses will confine you. If you have high nearsightedness, farsightedness, or astigmatism, your lenses will be thick around the corners or in the centre, making you uncomfortable. The weight and discomfort of these glasses make them feel more like a medical device attached to you rather than providing free and easy use.

High-index lenses, on the other hand, are thinner and lighter with a higher prescription than standard prescription glasses. It provides vision correction, ease of use, and comfort, making it an obvious better choice.

What is the Difference between High-index lenses and Standard lenses?

The weight and thickness distinguish high-index lenses from regular prescription lenses. These two lenses perform the same function and provide vision correction, but they differ in size, which is beneficial in terms of convenience.

Weight: High-index lenses are made of denser quality plastic and glasses material. Standard lenses are made of plastic and glasses that are simpler and less dense than high-index lenses. With increased lens density, it is possible to bend more light competently while using less material. As a result, these are referred to as "higher" indexes because the index refers to a material's ability to refract light. Because of their density, these lenses achieve refraction without the use of any additional material, making them light. People prefer it because it is lightweight.

To be able to refract light for higher prescriptions, standard lenses require more material, so more material is added. As a result, standard lenses are much heavier to carry around in your eyes. The weight of the lenses has an impact on the wearer's nose, making them feel as if they are carrying a stone on their face. People try to remove them whenever they are not needed because the weight is simply too much for children and adults.

Thickness: High-index lenses are significantly denser and do not require any additional material. 

This results in extremely thin lenses, which customers prefer. 

The thickness of the lenses provides comfort, style, and a wide range of frame options. 

Many times, people were unable to go rimless with high prescriptions due to the thickness being too visible, but with thin high-index lenses, it is a dream come true.

Standard lenses are thicker on the edges, which has a negative impact on their appearance and makes them prickly when choosing frames. Few frames can render its thick outer edges, and it does not fit. The thickness of these lenses is not appreciated because it prevents fashion from existing and forces you to wear simple-looking single frames for the majority of your life.

The Advantages of High Index Lenses

Flexibility: High index lenses, with their slim shape and narrow edges, allow wearers to choose from a wide range of fashionable frames. Because of their small size, they can be easily paired with sleek metal frames or incorporated into rimless eyewear for an appealing barely-there look, and they won't protrude from behind more streamlined frames.

Comfort: High index lenses are more comfortable for extended use because they are lighter than traditional counterparts. Because they're lightweight, you won't have to constantly adjust them due to sliding — and they're also gentler on your nose and ears.

Choices: High index thin lenses have many of the same options as traditional lenses, including the ability to be single-vision or progressive. Progressive lenses offer multifocal functionality, combining up to three separate prescriptions for reading, distance, and midrange vision in a single pair of eyeglasses.

Photochromic high index lenses (also known as light-adaptive or variable-tint lenses by some eyeglass wearers) are also available. When worn indoors, this versatile type of corrective lens is clear, but when worn outside, it transitions to a darker shade.

Aesthetics: High index lenses eliminate the bulky, bottle-glass appearance for users with strong prescriptions. This can help to reduce the unsightly bug-eye effect that has traditionally been associated with very thick lenses.
