When Should I Use Reading Glasses?

Which kind of lens can correct myopia?

Myopia is corrected by glasses with concave lenses, which are the thinnest in the center and thicker at the edges. The strength of the lens used to improve myopia is measured in diopter (D). The prescription for myopic glasses always begins with a minus sign. The higher the magnification of the lens, the better the effect of correcting myopia. High refractive index lenses are usually recommended to correct myopia with a diopter greater than -3.00. The lenses are thinner and lighter than regular plastic lenses, making them more attractive and comfortable. At the same time, an anti-reflective coating is strongly recommended for the correction of myopia lenses. The augmented reality coating eliminates scattered reflections in the lenses, making them look thinner and more attractive.


Different Types of Progressive Lenses

Premium progressive lenses are designed to provide a wider and smoother view. These lenses are highly customizable for your prescription, chosen frame and eye anatomy.

Premium progressive lenses can incorporate your dominant eye into the design and make transitioning between different prescriptions feel smoother as well. However, due to these features, premium progressive lenses are more expensive than traditional lenses.



What are night driving glasses?

Night driving glasses are usually non-prescription glasses with yellow lenses and can be bought in many optical stores or online. Lenses range in color from light yellow to amber, and some night driving glasses have an anti-reflective coating. The yellow night driving glasses have been manufactured and sold for decades. They were originally sold to hunters as shooting glasses because they gave birds a sharper contrast to the sky on overcast or overcast days.


Features of TR90 Frame

It has the characteristics of wonderful toughness, crash resistance, wear resistance, and low friction coefficient, which can effectively prevent damage to the eyes and face caused by the fracture and friction of the frame during the movement. Because of its specific molecular structure, and chemical resistance, it is not easy to deform in a high-temperature environment. It's very elastic, and it doesn't deform. The use of thermoplastic materials in these frames provides pretty strength due to their flexible characteristics.

Consumers should choose different styles of frames according to their age and professional characteristics. Because everyone has different face shapes, different interpupillary distances, and different diopters, the size of the frames should vary from person to person.

Lenses are divided into glass lens, resin lens, and PC lens, and you can choose according to your preferences. The glass lens has a stable refractive index, good abrasion resistance, and stable optical performance, but it is relatively heavy and easy to break. Resin lens with high light transmittance is light, safe, and not easy to break, but the surface is easy to wear. PC lens has a high refractive index, but the surface is easy to wear.


What are pure titanium rimless glasses?

Pure titanium rimless glasses combine the advantages of pure titanium glasses with rimless glasses. Rimless frames are mainly focused on lightweight, reducing the pressure on the wearer and enhancing comfort. Moreover, rimless frames are not obvious either in appearance or in weight, which alleviates some of the distress caused by myopia. Pure titanium material increases this lightness to the extreme. Pure titanium frame has a uniform and natural color. It is not easy to fade, not easy to rust, and anti-allergy. It is the pursuit of high-end taste glasses lovers' first choice.

How to Remove Coating from Glass Lenses?

To remove anti-glare coating from glass lenses, you need to prepare the following things: isopropyl alcohol, plastic scraper of some kind, salt water, water, plate or bowl.

Now, we will show you how to remove coating from glasses.

  1. Mix 5 parts of isopropyl alcohol with one part of saltwater.
  2. Place your glasses onto a plate and pour out the prepared solution just enough so the lenses are entirely submerged.
  3. Let it sit in the solution for an hour to soften the anti-reflective coating.
  4. Scrape off the anti-reflective coating using a plastic scraper.

After that, you have removed coating from glass lenses.
