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.
- Mix 5 parts of isopropyl alcohol with one part of saltwater.
- Place your glasses onto a plate and pour out the prepared solution just enough so the lenses are entirely submerged.
- Let it sit in the solution for an hour to soften the anti-reflective coating.
- Scrape off the anti-reflective coating using a plastic scraper.
After that, you have removed coating from glass lenses.
Features of Beta titanium glasses frame
Beta titanium has better strength, fatigue resistance, and environmental corrosion resistance than pure titanium and other titanium alloys. The shape plasticity is very good, which can be made into wire and sheet, more lightweight. They are used to make glasses and can get more shapes and styles. It's the material for a new generation of glasses. Customers with higher requirements for style and weight can completely choose beta-titanium glasses. Because β titanium processing technology is higher than pure titanium, usually only large factories and brands will produce, and the price is higher than pure titanium glasses.
What are the causes of lens damage?
When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.
In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.
What Are High-Index Lenses?
High index lenses are eyeglasses lenses that are designed to be thinner and lighter than regular lenses. High-index lenses have a high refractive index than their conventional counterparts. So, they are generally recommended for people who have significantly high refractive errors and strong prescriptions for nearsightedness, farsightedness or astigmatism.
High-index lenses correct all types of refractive errors. And they are also available as single vision lenses, or a reading prescription that corrects presbyopia, such as in a bifocal or progressive lens.
High-index lens has a higher refractive index and which is ranging from 1.53 to 1.74. A lens with an index of 1.74 could be up to 50 percent thinner than a regular plastic lens with an index of 1.50.
What can I do if the rimless glasses frame is broken?
It depends on the material of the frames. If it is a metal frame, the welding effect of 50 yuan is not worth looking forward to, because the high temperature will burn the welding point and the surrounding color. The electroplating will be destroyed, and it is difficult to accept the appearance. If the metal material is alloyed copper, it will quickly corrode and produce patina. If your frame is broken in a temple, you can fix it yourself with 502 glue or duct tape, but the look will definitely be affected. Or you can go to the optician shop to change the temple. But if all the temples are broken, it's impossible to repair.
Colored translucent frame
Colored translucent lenses have been popular since 2016. Some stars like a warm tan lens. Besides translucent lenses, what's popular this year is that the frames are made in a colorful translucent style. Wearing them can automatically cool down. Stella Mccartney 2020 spring/summer sunglasses are designed with colorful translucent material and a thick frame. In addition, a metal chain is added, which is all the popular elements this year.
Uvex Stealth OTG Safety Goggles
They provide more protection and coverage than other prescription safety glasses. Due to the full seal around the eye, these OTG safety goggles prevent chemical splashes, and bumps, and scratches, making them wonderful general-purpose safety goggles to wear over your prescription glasses. Dura-Streme's scratch-resistant coating helps keep the lenses crystal clear, which is especially important when wearing the underlying glasses.
