How to Avoid the ‘Coke Bottle’ Look for High Prescription Glasses

class="embed-responsive-item">

We’ve all heard the term “coke bottle glasses” – those thick, heavy lenses that can make your eyes appear magnified and your frames seem oversized. If you have a high eyeglass prescription, you might be concerned about avoiding this look while still enjoying the benefits of clear vision. The key to achieving this balance lies in your choice of eyeglass frames and lens materials. Here’s a guide to help you pick the right glasses and embrace a sleek, stylish look without the burden of thick lenses.

Select the Right Frame Size

The first rule of thumb is to choose a frame that’s not too oversized. When you have a high prescription, larger frames can lead to thicker, protruding lenses. To avoid the “coke bottle” effect, opt for frames that are more proportionate to your face. Look for styles that are not excessively wide or tall, as this will help reduce lens thickness.

Invest in Hi-Index Lenses

The second and equally crucial step is to select hi-index lenses. These lenses are thinner and lighter, providing both aesthetics and comfort. Zenni’s hi-index lenses are made out of MR material from Mitsui Chemicals. Hi-index lenses are designed to reduce lens thickness and weight, making them a game-changer for high prescription wearers.

Here’s a quick guide to help you choose the right hi-ind`ex lens based on your prescription:

Hi-Index 1.61: Ideal for prescription powers between +/- 3.00, offering significant reduction in lens thickness and weight.

Hi-Index 1.67: Perfect for prescription powers ranging from +/- 3.00 to +/- 5.00, ensuring a sleeker profile without compromising on clarity.

Hi-Index 1.74: If your prescription exceeds +/- 5.00, these lenses are your go-to choice for the utmost reduction in lens thickness, giving you a remarkably thin and lightweight solution.

In summary, avoiding the “coke bottle” look with high prescription glasses is achievable through thoughtful frame and lens choices. Opt for frames that aren’t oversized and complement your face’s proportions. Hi-index lenses, like those made from MR material by Mitsui Chemicals, offer thinner and lighter options. They come in various indices, from 1.61, 1.67, and 1.74, catering to different prescription powers, ensuring a sleeker profile without sacrificing clarity. With the right combination, you can enjoy clear vision and a stylish appearance, free from the thick, heavy lenses of the past.
