What Are the Advantages of High-Index Lenses?
In this section, we will show you the advantages of high-index lenses.
- Thanks to the slim shape and narrow edges, high index lenses offer wearers the flexibility to choose from a wide array of fashion-forward frames. Their size means that they can be easily paired with sleek metal frames or incorporated into rimless eyewear for an attractive barely-there look.
- High index lenses are more comfortable for extended use because they are lighter than the traditional counterparts.
- High index lenses are available with many of the same options as traditional lenses. For example, they can be either single-vision or progressive.
- For users with strong prescriptions, high index lenses mean no bulky, bottle-glasses appearance. This can reduce the unwanted bug-eye look traditionally associated with very thick lenses.
However, there are some negative voices of high index lenses.
Advantages of Progressive Lens
Continuous and clear vision throughout the entire process is the advantage of progressive lenses. Because the added value continuously increases gradually in the gradient zone, the wearer can obtain continuous clear vision from the far point to the near point through the gradient lens under the appropriate head position. In line with physiological optics, better adaptation. The appearance is better than that of double-lens and triple-lens. There is no dividing line of sub-sheets, and there is no ring-shaped blind zone and invisible sub-sheets.
You can buy glasses of new eyewear brands.
Some emerging glasses brands are completely independent brands. Their own processing team and the processing instruments are imported instruments. The processed glasses are very standard, and the work is very careful. There are many choices for styles. The most important thing is that the color is good, it is not allergic, it is not easy to fade, and it can go with everything. Whether from their own grade or design, they have their advantages.
The anti-reflection principle of the anti-reflection film
Anti-reflection Coating, known as anti-reflection membrane, is called anti-reflection coating in English, or AR membrane for short. The basis of anti-reflection is the wave and interference of light. The principle is: Two light waves with the same amplitude and the same wavelength are superimposed, then the light wave amplitude is enhanced. The two wavelengths and amplitudes are the same, but the superposition of wavelengths with different wave paths (similar to dislocation) cancels each other out. Therefore, the anti-reflection film plated on the surface of the lens uses this principle to make the reflected light generated by the front and rear surfaces of the film layer interfere with each other, thus canceling each other and achieving the effect of reducing reflection.
How to protect your contact lenses?
When wearing contact lenses, do not drop any eye drops, and only use a special moistening solution for contact lenses. In daily life, we recommend that dry eyes can be relieved with lubricating fluid, but we do not advocate frequent use of lubricating fluid, so as not to make the eyes become dependent on lubricating fluid. The right way is to do blink training. The ingredients contained in the eye drops will remain in the lenses, which will cause certain damage to the eyes and pollute the lenses. Some eye drops can make the lenses tinted after use, which will affect the transmittance and a refractive number of the lenses and make the vision blurred. Ladies who need to make up should wear contact lenses before making up. When removing makeup, remove contact lenses before removing makeup, to avoid the makeup sticking to the lens and damaging the lens and eyes. Lenses should not be lent to others to avoid cross-infection of eye diseases. You can't wear contact lenses while swimming or bathing.
Are blue light glasses good for driving at night?
Are blue light glasses helpful when driving at night? The answer is not necessarily. Anti-reflective coating on glasses is beneficial. But blue light blocking won't have any effect on your driving at night. If your glasses have an anti-reflective coating, then they might be helpful for night driving. Otherwise, they won't have any impact.
The Benefits of Anti-Glare Glasses
Anti-glare glasses or sunglasses help to reduce the light and provide you with a clear field of vision, especially for outdoor sports.
Anti-reflective coating glasses can also reduce eye strain and eliminate the stress on your eyes.
Digital devices such as phones, laptops, tablets, and TVs all emit harmful blue light. The anti-reflective coating glasses can help to reduce your exposure to blue light, improve your sleep pattern, and reduce eye strain.
