GLASS LENSES

Glass prescription lenses still offer the best visual acuity of any eyeglass lens, as they have for hundreds of years. Glass lenses typically boasts an index of refraction within the range of 1.523 to 1.7.
Beyond their exceptional clarity, glass lenses offer another alluring feature: scratch resistance and durability. Glass lenses are known for their exceptional ability to withstand scratches better than any other material used to make spectacle lenses. It’s important to recognize that no material used to make spectacle lenses is completely impervious to scratches. Glass lenses also show strong resistance to strong solvents and abrasive solutions, such as paint thinner and acetone.
Nonetheless, it’s essential to consider the weight of glass lenses, which stands as their primary drawback. Glass lenses are notably heavier than other spectacle lens materials. To meet FDA impact resistance standards, they must undergo chemical or heat treatment.
It’s also noteworthy that advancements in technology are steadily enhancing the durability of coatings for plastic and polymer lenses, offering more durable alternatives to glass lenses.

    It depends on your individual needs and preferences. Glass lenses are more scratch-resistant and durable than plastic lenses, but they are also heavier and more easily breakable. Glass lenses also tend to be more expensive than plastic lenses.On the other hand, plastic lenses are lighter and less likely to break, but they are also more prone to scratches and other damage. They are also less expensive than glass lenses.

    You can try to reduce scratches on glass lenses using methods like toothpaste or baking soda. This entails rubbing the region that has been scraped gently with a towel after applying toothpaste or a paste made of baking soda and water. Please be aware, though, that these techniques can only make the scratches look better—they might not be able to entirely erase them. We suggest replacing glass lenses as soon as possible if they have scratches on them.

    Glass lenses that have super glue on them should be carefully scraped off, soaked in warm, soapy water, and then the adhesive residue gently scrubbed or rubbed away. To prevent breaking the lenses, try again if needed and get expert assistance if the glue is very hard to remove. Do not use nail polish remover or acetone.

    Glass lenses have different reading prescription types, including single vision, bifocal and progressive. In single vision, they have index 1.523 and high index 1.7. Clear lenses and photogrey, photobrown lenses are all available.

    The cost of glass lenses depends on various factors such as the type of lenses, coatings. In addition, different prescriptions are in different cost. Please contact our sales, and they will quote.
