High Index 1.74 Transition Lenses – WHAT THEY ARE AND HOW TO USE THEM

The term “high index” refers the refractive indices of lenses. The refractive lens index measures the lens’s ability bend light. The higher the index, the better the lens will be at correcting vision and bending light.

They are also very powerful. High-index lenses can correct vision problems that are more severe while taking up less space than other eyeglasses.

The higher the refractive index of a lens, the stronger the prescription without needing to add thickness.

What prescription strengths require high-index lenses?

High-index lenses are recommended for eye prescriptions between +/-4.00 to +/-8.00. High-index lenses are recommended for those with prescriptions of +/-4.00 to +/-8.00. We recommend 1.74 lenses for those with prescriptions in between.

High-index lenses are not noticeable by people with low prescription strengths. Your optometrist will be able to determine what is best for your prescription.

WHAT ARE THE ADVANTAGES OF High Index 1.74 Transition Lenses?

  • They are thinner, lighter and less noticeable within frames. Unlike thicker lenses which may protrude. Low-index lenses may also enlarge or reduce the size of your eyes. This is less likely to happen with high-index lens. .
  • They are versatile. You can choose from high-index lenses that are single vision or progressive. You can even get light responsive. High-index lenses can be ordered that filters blue light. If you are getting sunglasses, high-index polarized lenses are also available. High-index lenses are a great option for customizing your prescription lenses.
  • These lenses fit into most frames. You can choose from a wide range of frames styles even if your prescription is higher. We recommend selecting a frame which centers your eyes behind the lenses to reduce your lens thickness. This is even more important if your prescription is strong! The larger the frame, the thicker the lenses (regardless of refractive index).
  • They are comfortable. High index lenses will not sit heavy on your nose or ears and will be less likely to slide down compared with thicker lenses.

WHAT ARE THE DISADVANTAGES OF High Index 1.74 Transition Lenses?

  • They are not as resistant to impact as other lenses. They’re not the best option for children, or those who play high-contact sports. High-index lenses can be slightly more fragile than other lenses.
  • High-index lenses are more expensive than conventional lenses. Because of their materials and manufacturing processes, they can increase the cost of your eyewear. High-index lenses can cost hundreds of dollars extra. Ordering high-index lenses at VS Eyewear will cost you between $50 and $150.
  • They are more reflective than any other lens. They are more reflective than other lenses. This can cause distractions in bright environments. This can make driving and seeing at night more difficult. Antireflective coating for high index lenses is therefore essential. All of ours are already coated with this coating.

VS Eyewear understands that everyone has different visual requirements. We offer a wide range of high index lens replacements to suit your prescription, budget, and preferences. We also offer a full range of high index glass lenses for existing glasses.
