What Does Rx Ready Mean?

The principle of the anti-fog lens

Ordinary lens materials and water are wet, so water vapor is easy to fog up on the top. If this wetting relationship can be broken, the water vapor can be prevented from fogging up on the surface of the lens. The anti-fogging film is a kind of film which can prevent or avoid water mist agglutination effectively. It is divided into organic film and inorganic film. The inorganic film is mostly used for building, car window glass fogging prevention. For lens anti-fogging, the organic film is more used. The method is to wipe, spray (with an anti-fogging agent, and so on).


Sports goggles

With the improvement of people's sports concept and sports protection concept, sports goggles are also widely welcomed. Safety glasses are worn during sports must have four major functions, safety (PC lenses), protection (TR-90 frame, soft and flexible), comfortable (non-slip nose pads and foot covers), and beauty (match sports and leisure clothing).

Sports goggles with shatter-resistant plastic lenses and side shields can prevent balls or sand from hitting the eyes. It can be fixed on the head without worrying about falling off during intense movements. The unique design of the rim of the frame makes the glasses very close to the human face and has a proper external isolation effect so that the human eye is not easy to be attacked by bacteria. The special lens has the functions of anti-fog, anti-shock, and ultraviolet rays, which is very suitable for outdoor activities.



What are the benefits of the TR-90?

Impact resistance is more than 2 times of nylon material, in order to effectively prevent the damage to the eyes caused by impact in the movement. It has high-temperature resistance. 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. It is not easy to deform and change color, making it wear for a longer time. Having no release of chemical residues, it is in line with the European requirements for food-grade materials. The weight is less than half of the weight of the plate frame, 85% of nylon material, reducing the burden of nose bridge, ears, and making wearing more comfortable.


Half frame glasses

The half-frame glasses are more appropriate. A round face is wide on the left and right. For the half-frame, because it doesn't have a line underneath it, it will make the face look rectangular. Wearing the full-frame will make the jaw look narrower, and the jaw of a round face is narrow, so wearing the full-frame will make the jaw look narrower. Wearing a half-frame lengthens the jaw and makes up for the lack of a round face. On the other hand, full-frame glasses are more suitable for long faces.



What factors make you receive glasses on the same day?

Are your lenses anti-glare or anti-scratch? This may extend the time it takes you to buy glasses. Is your prescription complicated? If so, it could mean your lenses take longer to make. Your favorite frames that you tried out at the store are just for display, so you have to order frames for your glasses. If that particular frame style is in small quantities at the factory, your delivery may be delayed. Some optometrist offices and eyewear retailers have in-house optics LABS. These LABS can make some eyeglass lenses in an hour or so. But the power and design of the other lenses needed to be manufactured by an external optics lab, which took more time.

How to drive at night with glasses?

If you need to wear glasses while driving, you'll need special glasses when driving at night, because common lenses reflect oncoming lights, which produces a faint glare. This will reduce your visibility. It's OK to wear contact lenses while driving. As you get older, your eyes become more sensitive to glare. Ordinary sunglasses or goggles are only suitable for wearing during the day, driving at night will seriously affect the vision (national standards stipulate that light transmittance of night driving glasses must be greater than75%). Although the all-weather driving glasses can weaken the strong lights, the vision darkens and affects road safety which does not meet the national standards for driving glasses at night. You should choose functional driving glasses that can block strong light, glare and increase the field of vision. This can effectively reduce the glare of the car lights but can filter out the extra harmful light. When worn at night, it can soften the strong lights and make the vision clearer. In this way, the safety of drivers is ensured, the fatigue of eyes is alleviated, and the radiation damage of harmful lights to glasses is prevented.
