The YAG laser safety glasses have a polycarbonate green lens filter that provides laser protection. These laser glasses have visible light transmission of 54%. In addition, the YAG laser safety glasses have ANSI Z87+ and ANSI Z136.1 safety standards and CE certified lens. These laser safety glasses 33 is a durable and lightweight fitover frame. Made of high-quality plastic, the 33 laser safety glasses feature adjustable temples and integrated side shields. These Phillips Safety laser safety glasses are available in black.

Polycarbonate lenses are impact resistant and offer increased durability, but are generally only recommended for children’s glasses, sports eyewear and safety goggles because they don’t provide the same level of visual clarity, when compared to other plastic lenses.

While high-index lenses can be beneficial for certain optical prescriptions, they can also be more expensive than regular lenses.

A lens for nearsightedness is designed to be thinner in the center but thicker around the edges. With a strong prescription and regular thick lenses, your choice of eyeglass frames will be limited— especially if you were hoping to purchase rimless or semi-rimless frames.

High-index lenses are eyeglass lenses that are designed to be thinner and lighter than regular lenses. They are generally recommended for people who have significantly high refractive errors and strong prescriptions for nearsightedness, farsightedness, or astigmatism.

High-index lenses contain a unique aspheric design which facilitates a flatter lens curvature, leading to reduced magnification and improved appearance.

Regular lenses for a strong farsightedness prescription can be quite heavy. High-index lenses however, don’t require as much lens material and will result in longer lasting comfort.

Many eye care professionals also recommend adding anti-reflective and anti-scratch coatings to high-index lenses to improve vision and lens durability — this will further increase the overall cost of your new eyeglasses.

This index is adequate for correcting mild to moderate refractive errors, but is not as effective for the correction of higher refractive errors.

Also, it is important to know that high-index lenses are typically more fragile than regular lenses and need to be handled with a bit more care.

High-index lenses are generally scratch resistant and can fit into almost any type of frame. They can also be treated with anti-scratch, anti-reflective, and UV-protection coatings to improve vision and lens durability.

With a thicker lens, these types of frames can be less attractive and also more difficult to wear, as thicker lenses are not as secure within the frame and are more likely to pop out.

More recently, the newest trends in eyeglass frames include plastic and metal rimless frames, as well as frames that contain thinner rims which expose the edge of the lens.

Also, as opposed to lenses for nearsightedness which are thicker on the edges, lenses for farsightedness are thicker in the center. With regular lenses, this can significantly magnify your eyes and may make you feel a bit self conscious at times.

Before choosing high-index, speak with your eye doctor to determine if these lenses are necessary for your individual prescription.

According to this table, a lens with an index of 1.74 could be up to 50 percent thinner than a regular plastic lens with an index of 1.50, with the same optical prescription.

The refractive index is the number that represents how efficiently a lens material bends light, and is dependent on how quickly light travels through the material.

High-index lenses can improve lens comfort and appearance, and can even open the door to a larger variety of frames.  High-index lenses may be just the solution you have been searching for.

Regular lenses that contain a strong optical prescription usually require a thicker and heavier lens in order to bend light more effectively and correct the high refractive error.

While both regular and high index lenses function in the same way, high index lenses are designed to bend light more efficiently — leading to thinner and lighter lenses.
