What is the difference between Phoenix and polycarbonate lenses?

They are also very resistant to unusual problems, like several chemicals. They can resist acetone, which few plastics can resist, including polycarbonate. Acetone is a common chemical in nail polish removers and some other solvents that may be around your house. Children can also benefit from Trivex glasses, being that they are more prone to forgetting, dropping, crushing, or damaging their glasses. People who benefit from the outdoors or work consistently outdoors can reap the benefits of Trivex. The ultraviolet protection, great visual clarity, and strong material make sure they are a good choice for those with active lifestyles, like hikers or runners.

  • It is possible to book your
  • This may be an excellent option, especially if you have a card that carries a low interest, offers points or other rewards.
  • A small portion in the low section of the lens contains the power necessary to correct your near vision and the rest of the lens is usually for your distance vision.
  • Tints of nearly every color can be put on eyeglass lenses.

However, since glass is more brittle than most materials, lenses made of glass should be tempered or heat-treated to give them more strength and make sure they are safer to wear. As mentioned above, the bigger the index, the thinner a lens will undoubtedly be for confirmed power. However, the precise gravity also increases dramatically with the index making high-index glass lenses much heavier. Chromatic aberration can be more pronounced in high-index glass. [newline]The majority of eye care providers use polycarbonate material as their most typical lens. Because polycarbonate lenses are thin, light weight and impact resistant. Lenses made from the Phoenix material are actually 10% lighter than polycarbonate lenses while preserving the impact resistance.

Prescription Lenses And Frames

This may be a good option, especially if you’ve got a card that carries a low interest, offers points or other rewards. If you want help navigating the planet of prescription eyewear, or if you want to make a watch exam appointment, contact Michigan Eye Institute. Glare is nuisance light that enters your eye and inhibits your vision. It can come directly from the source of light or be reflected. Depending on intensity of the light and what you’re doing once you experience glare, it could simply be distracting or it is usually extremely dangerous. There are many working conditions that present multiple eye hazards.

Other benefits include resistance to chemicals and better light refraction. However, this lens material could be expensive and difficult to find. Eyeglasses are very easy to break, especially lenses and frames. If you need to change the style of your glasses, it is advisable to ask a professional. The anti-reflective coating decreases unwanted glare and halos at nighttime. In addition, it makes the lenses appear somewhat invisible and incredibly thin. Trivex is lighter in weight than standard plastic but not quite as thin as polycarbonate.
Semi-rimless frames are also a perfect choice for those who benefit from the extra comfort and minimalist feel. Lenses made from Trivex are extremely resistant to common problems like being dropped or scratched.
Your professional optician can discuss the pros and cons of polycarbonate and Trivex lenses so that you can decide which lens material is the better choice to your requirements and budget. Polycarbonate lenses are available in a wider variety of lens designs (e.g., progressive lenses and other multifocals) than Trivex lenses. Just like our Hoya Phoenix, our Seiko 1.60 is aspheric, which may decrease the thickness of the lens purely through design rather than material. Again, a lot of the online stores out there will go with spherical lenses only. Also, just like our Phoenix, the Seiko 1.60 has a premium lens treatment. My goal, beyond protecting myself, would be to make sure that they’re fully protected against a lifetime of blue light exposure. BluTech Lenses are infused with Blue Light Plus, a proprietary combination of pigments and dyes which protects your eyes just how nature does.

Your Eyewear Options Aren’t Limited To Your Frames

Furthermore, aspheric curves come standard in many high index products, particularly 1.66 and 1.70 products, and are obtainable in 1.60. Asphericity reduces spatial distortion, reduces magnification or minification, and further helps maintain a thin and flat lens profile. High index material, however, will have a lower Abbe value which could potentially affect patients that are sensitive to chromatic aberration. Also higher index and flatter curves tend to result in more backside and inner-surface reflections. AR coatings are often recommended for high index lenses to get rid of these reflections.

  • R and L are used as some use R for right and L for left instead of OS and OD.
  • We have NXT Photochromic lenses and Drivewear lenses (CR-39 and Polycarbonate only).
  • You can still easily scratch the coating which will seem like scratches before coating is removed and replaced.
  • If a material has a greater ability to refract light, less of a curve must get yourself a specific power, resulting in a thinner lens.

On the other hand, polycarbonate lenses have an increased index of refraction than Trivex lenses. Therefore, polycarbonate lenses will be noticeably thinner than Trivex lenses. Still, Trivex lenses are thinner than regular plastic eyeglass lenses, that have a refractive index of just one 1.50.

They provide UV protection and prevent 99.9% of rays from sunlight, fluorescent lights and computer screens. Polycarbonate lenses are thinner than standard lens and for that reason more comfortable to wear.
Eyeglass lens material doesn’t change the corrective power of your glasses. Rather, eyeglass lens types offer different cosmetic and lifestyle advantages to the wearer. Besides its use in eyeglass lenses, additionally it is useful for car headlights, CDs and DVDs, and several other industrial applications. Polycarbonate is very strong, making it an excellent lens material.
