How Long Do Metal Frame Glasses Last?

Benefits and disadvantages of rimless glasses

Rimless glasses are more stylish colorful, and comfortable to wear, greatly easing the pressure on the bridge of the nose and eyes, and because there is no frame limitation, the wearer's field of vision is wider. They are loved by young people. After a period of time, the screws at the hole are easy to loosen. The wearer should often tighten the screws.(https://www.koalaeye.com/collections/rimless-glasses)

The quality and reputation of the store owner are affected. And because there is no support bracket, when the glasses are placed on a hard object, they will directly contact the lens, which is easy to cause lens wear. In addition, when the rotation or torque force is encountered, the force will directly act on the lens, so when the force is too large, it is easy to cause damage to the lens.


Titanium frame machining is complicated.

The elastic modulus of titanium alloy is small, which is easy to produce large deformation, springback, distortion, and vibration in cutting, resulting in poor geometric shape and accuracy of the workpiece. As the surface roughness increases, the tool wear increases. The thermal conductivity of titanium alloy is poor and its thermal conductivity is small, 1/6 of that of 45 steel, so the high heat generated in processing cannot be effectively diffused. It is even harder to use titanium to make glasses. The frames are very thin and a lot of fine work is demanded. It's definitely a challenge for titanium, which is pretty difficult to work with. In addition, titanium alloy frames involve titanium alloy welding technology, which is more difficult.



Advantages of Photophobia Glasses

Although the best way to deal with light sensitivity is to address the underlying causes, several studies have indicated that light sensitivity glasses may be helpful in alleviating and reducing discomfort when it comes to light sensitivity. After wearing the photophobia glasses, many symptoms such as headaches or eye pains, etc will be relieved.


Cheap frames can cause skin irritation.

Some cheap frames may look like more expensive frames. But more often than not, they are made of low-level materials that can cause skin irritation over time. Cheap plastic frames can be bleached by ultraviolet light, leaving the surface rough after months of wear and tear. Cheap metal frames often contain nickel alloy, which can cause skin irritation.



Powerful Function of Lens From KOALAEYE

The lens is flat with high clarity. The glasses have an anti-scratch coating, an anti-scratch coating on both sides of the lens, which can effectively reduce the wear of the lens and prolong the service life of the glasses. However, the scratch-resistant coating is not 100% scratch-free but is more scratch-resistant than uncoated lenses. They have Super Hydrophobic coatings, Oleophobic coatings, and ultraviolet protection functions. Glasses are not only fashion accessories but super weapons to protect eyes and restore clear vision.


What is vision insurance?

The term vision insurance is commonly used to describe health and wellness plans designed to reduce the cost of regular preventive eye care (eye exams) and prescription glasses (glasses and contact lenses). Some vision plans provide discounts on elective vision correction precesses, like LASIK and PRK. But unlike large health insurance plans, most vision plans are discount or health benefit plans that provide specific benefits and discounts on annual premiums. They can be used to cover most of the cost of eyewear, or they can be used to make high-end eyewear products and improvements, like progressive lenses, anti-reflective coatings, and photochromic lenses, which are much cheaper. Vision insurance plans usually operate differently than other health insurance plans or large medical insurance plans.

The cost of an eye exam

If you have a Walmart Vision Center near you and you need a new or updated prescription, you can schedule your eye exam there. Some vision centers have independent optometrists who work in offices next to Walmart. An eye exam at Walmart costs about $73, depending on where you live. Call your nearest Walmart Vision Center to get the exact price of an eye exam.
