What Are Adjustable Glasses?
Are you over age 40 and unhappy with your current glasses for the presbyopia correction? Most people with nearsightedness, farsightedness, or astigmatism need progressive lenses to see objects clearly. But some are frustrated by the relatively limited field of view these and other multifocal lenses provide for intermediate and near vision.
And, those people with presbyopia also have problems. They often are frustrated by forgetting to bring their reading glasses or are constantly needing to put them on and take them off to see clearly at a different distance.
If you also have the same trouble, here is some good news. You can use multifocal eyeglasses to solve these problems and give you clear, unobstructed vision at any distance with just a simple turn of a dial inside the eyeglasses frame.
And these glasses are called adjustable glasses or adjustable focus glasses. They are a versatile and affordable solution to correcting minor vision problems. They compensate for presbyopia and other refractive errors like farsightedness and nearsightedness. They are non-prescription glasses designed for everyday use.
You can see the top to look far away and look down to see near objects clearly because different portions of lenses offer different types of correction. With adjustable glasses, you have one focal length that varies depending on where you are looking.
Anyone can wear adjustable glasses, but they are especially beneficial for people who cannot afford regular glasses or for those who live in areas where regular glasses are not accessible.
Are progressive lenses expensive?
The PAL tends to be more expensive than other lenses because you are definitely combining three lenses into one. Digital PAL is more expensive, but they are more personalized and specific to your size. This is key to providing the best visual experience. The cost of progressive lenses depends on several factors, including your prescription, the brand of glasses you choose, and other factors. However, you must remember that one progressive lens can replace multiple pairs of glasses, which can save you money in the long run. The price of progressive multi-focus glasses is different with different styles and different brands, from more than a hundred to thousands of yuan. We must choose according to our own economic situation.
Features of pure titanium glasses frame
Due to the lightweight (ordinary nickel-based alloy frame weight 48%-60%), high strength, corrosion resistance, surface easy coloring, beautiful and durable features of spectacle frame made of pure titanium, they have been loved by most consumers. But the elastic modulus of pure titanium is higher (about 120GPa). The temples of the frames made from them are not elastic enough. After wearing the glasses for a period of time, the temples of the glasses need to be adjusted due to the relaxation of the stress. The processing plasticity of titanium metal is worse than that of other metal materials, so the processing technology of its wire is difficult. The surface quality is difficult to control, and the technical content is high. The surface quality of pure titanium wire produced by a few domestic manufacturers is poor.
Bifocal Lens
Bifocal lenses have two observation areas separated by visible lines, a larger observation distance area, and a smaller reading area. It may take some time for people who are wearing bifocal glasses for the first time to get used to the lenses. This is mainly due to learning how to move the eyes between the observation distance area and the reading area. Some people will also find that there will be an 'image jump' phenomenon at the visible line between the distance and the reading area, especially for those with limited mobility, who must look down when walking. The best way to get used to bifocals is to wear them as much as possible.
