Evolution of photochromic lenses

Thirty years after Corning invented color-changing glass lenses, another company has carried forward the color-changing glass lenses --Transitions Optical. In 1991, it became the first company to commercially manufacture resin color-changing lenses. Since its inception, the company has been a joint venture between PPG Industries (51%) and Essilor (49%). In April 2014, Essilor acquired a 51% stake in PPG. At present, the mainstream is resin photochromic lenses.


Why do you need rimless glasses?

Traditional full-frame glasses can sometimes make your face look heavy, especially if the lenses are thicker. Rimless glasses can replace heavy frames without weight from the rims. This reduces the pressure on the nose pad, making your face feel lighter and more comfortable.



How to Tell If Lenses Are Plastic or Glasses?

If you want to know if your glasses are made of glasses or plastic, the safest way is to ask the optician from whom you bought the glasses. If you do not want to ask the optician, there are several ways to differentiate them, such as sound, weight, and temperature.

Lightly tap the lens against your teeth or your ring. If the lens emits a high, ringing tone, it is a glasses. On the contrary, the plastic will have a low thud like sound when tapped.

Glass lenses are much heavier than plastic glasses and glass lenses feel colder to touch while plastic glasses feel warmer since it is a better insulator.

After learning what lenses you have, it is time to show how to remove coating from glasses.


Choose clear glasses for kids of suitable temples and nose pads.

Children's head is very different from adults, especially the height of the bridge of the nose. Most children's bridge of the nose is low. Therefore, it is best to choose a high nose pad for children's glasses or an adjustable eyeglass frame for the nose pad. The temples of the glasses should not cause uncomfortable pressure and the glasses should be kept in the correct position. Sporty temples are another option. The temples are very flexible, and they fit well into a child's ear. It should extend to the earlobe and be covered with soft plastic.



Use the fishing sunglasses correctly.

Fishing enthusiasts should try to avoid wearing sunglasses that are easy to oxidize and corrode. They should wear sunglasses that are not easy to oxidize and corrode, such as plate frames, aluminum and magnesium alloy, pure titanium, and titanium alloy. Do not put the fishing sunglasses in a high-temperature environment for a long time, and do not immerse the fishing sunglasses in water for a long time. Avoid contact with perfume, insecticide, and other items containing chemical components to avoid chemical corrosion of lenses and frames and better protect your sunglasses. When they are not in use for a long time, please put them in a special bag so that the lenses can be taken good care of.


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.
