Like most people who buy prescription eyeglasses at local stores, you probably associate high-quality eyeglasses with a high price tag. But are expensive eyeglasses that much better than their cheaper counterparts? As long as you consider these factors below, you should be able to find the proper prescription eyeglasses to correct your vision and protect your budget.
When it comes to prescription eyeglasses, the first that cannot be avoided is the eyeglass frame. So, what factors determine the quality of a pair of eyeglass frames? Generally speaking, there are three main factors: material, craft details, and shape.
METAL glasses frames are generally made of copper, nickel, and precious metals. Eyeglasses frames with these rare metals are better hard, can fight strong impact; and are anti-corrosion good than other materials to noticeable effect. However, metal eyeglass frame texture generally, toughness and elasticity are poor, and encounter sweat is more likely to slide.
The biggest thing about PLASTIC eyeglass frame is that it is one of the best anti-corrosion and is a higher material. Many consumers also love its sun and environmental protection; it is a light material and low cost.
ACETATE glasses is currently the most popular eyeglass frame material and is also the more widely used eyeglass frame material. It is very resistant to erosion and rusting compared to other materials. In addition, the polished and shaped acetate eyeglasses frames have a high gloss, translucent, soft texture, and are suitable for any skin type.
So looking at whether a pair of eyeglasses frame is good or bad is to ask more about the material: titanium is more expensive than ordinary metal, and acetate is definitely more expensive than regular plastic. Next, check the details: the opening-closing of its hinges, its surface's smoothness, and the metal welding's flatness. Finally, of course, each person has their favorite frame shapes.
As the soul of prescription eyeglasses, the prescription lenses are the key to whether or not these eyeglasses will cause damage to our eyes. But, of course, lenses' attributes are numerous and demanding, and we also look at the main ones.
Ordinary clear prescription lenses check whether the surface of the lens is smooth and free of scratches, whether the vision through the lens is clear, and whether the cover has a reflective green or blue coating.
If you know you have old glasses that you originally used, you can use them to compare the thickness of the lenses under the same size frame. Generally, the thinner the lenses, the higher the price.
Of course, prescription lenses contain so many attributes that, as a rule, on top of the above, eyeglasses worn after the adaptation period without dizziness and clear vision will not harm our eyes.
