Trivex along with polycarbonate is great for rimless frames and the ones frames requiring drill mount screws through the lenses. High index lenses offer a thinner lens but usually have lower abbe values. The Abbe value determines to a big part the optical integrity of the lens. Eyeglasses are very easy to break, especially lenses and frames.
The eyeglass lens type and eyeglass lens material that is best for you will depend on several factors, together with your vision correction needs and lifestyle.

The truth that it’s available in a variety of colors is another plus. Aluminum is lightweight and, when alloys are added, super strong.

There Are Different Lens Materials To Meet Up Different Needs

Created from plastic, High-Index lenses are specially made with a higher refractive index to raised bend light and improve vision correction. Both are produced from the same plastic-type material but High-Index 1.74 lenses are thinner and are better in stronger prescriptions. Our polycarbonate lenses include edge polish and scratch-resistant and UV-protective coatings at no additional cost.
And, finally, you have choices for eco-friendly eyeglass frames. For styling thin, lightweight, or hypoallergenic frames, titanium is tops. Selecting a small lens size frame is the biggest determinant of lens thickness and weight! Smaller frames also decrease the level of lens distortions/aberrations. Magnesium may be the eighth-most abundant metal element on the planet. Lighter than both titanium and aluminum, magnesium is either extracted from the ocean or recovered from minerals such as dolomite or magnetite. Due to its unique properties and high cost, it’s been found in the high-end frame market.

• For this reason, it has generally been replaced by nylon blends – polyamides, copolyamides and gliamides – which tend to be more durable.
• We offer the highest-quality lenses on the planet, but at not even half the cost you’d expect to pay at an average optical store.
• Because it’s a stiff material, nylon frames aren’t as an easy task to adjust as zyl, for instance.
• The eyeglass lens type and eyeglass lens material that’s best for you depends on several factors, together with your vision correction needs and lifestyle.

Scratch-resistant coatings are put on leading and back of lenses in the manufacturing process. Flatter peripheral curves also reduce distortions that occur when looking away from the biggest market of the lens, making vision crisper. The abbe value may be the number of chromatic aberrations in a lens. The higher this number is, the higher the quality of vision through the lens will be. Polycarbonate lenses also have built-in ultraviolet protection. CR-39 lenses have a higher Abbe value of 59.3 making them the lenses with minimal distortion from dispersion/chromatic aberration. Ultraviolet treatment is put on lenses to safeguard against harmful UV light that can accelerate the development of cataracts and macular degeneration.

Photochromatic Lenses

Monel,™ probably the most commonly used frame material today, is frequently used for components that require sturdiness and rigidity, such as temples and bridges.
