Did you know that standard lenses transmit around 91% of light to the eye? The rest is lost due to surface reflections. Anti-glare glasses help solve that problem. If you didn’t know the role played by reflection when wearing prescription glasses and are not sure whether or not to get anti-glare glasses, this article will help you understand better.

Lens coatings are significant because they are vital in providing durable and long-lasting lenses for your eyeglasses. Unfortunately, not everyone knows the different types of lens coatings you can choose from; or worse, some don’t even know such protective layers exist.

Thanks to the coating, anti-glare glasses reduce the light reflecting off the lenses, resulting in more light passing through and having more clarity. Not only will you be able to see better, but the glasses will also help with surface reflections and give you greater visual performance.

Anti-glare coating is not mandatory, but it is advised as it enhances the overall performance of your glasses. Not only will you have clearer vision, but you will also look better and struggle less while doing your everyday activities.

Remember to avoid cleaning your glasses with shirts or chemical cleaners, as this might be damaging to your glasses. If you want to read more about lens coatings, we have an informative article right here.

No, anti-glare and blue light glasses are not the same, as they are two types of coatings and are designed for different purposes. Anti-glare coatings are designed to increase the amount of light passing through the lenses, while blue light glasses are designed to block the blue light coming off screens.

There are also a few disadvantages when getting anti-glare glasses, including the increased need for cleaning. After getting your pair of anti-glare glasses, you might want to clean them more often because anti-glare glasses highlight dirt or dust.

No, anti-glare cannot be added to your lenses after the purchase. If you need to decide whether or not to add anti-glare coatings to your glasses because of the price, remember there are many affordable online options that let you add an anti-glare coating to your lenses without breaking the bank.

One of the lens coatings you can choose from is anti-glare coatings, also called anti-reflective coating. These lenses are provided with a microscopic multilayered coating that eliminates glare and reflections from the back and front of your eyeglass lenses. As a result, it helps with clearer vision.

Clinical observations have suggested that low-energy lasers might promote wound healing. Evidence suggests that He-Ne laser irradiation induces an increase in the rate of keratinocyte migration and proliferation as compared with nonirradiated controls in vitro. This study sought to determine whether He-Ne laser could induce cytokine production in cultured keratinocytes. The results revealed (i) a significant increase in interleukin-1 alpha and interleukin-8 production and their respective mRNA expression in He-Ne laser-treated groups as compared with nonirradiated controls, and (ii) under 1.5 joules/cm2 irradiation, this stimulating effect of He-Ne laser treatment is concentration-dependent. Because interleukin-1 alpha induces keratinocyte migration, this finding may partially explain the stimulatory effects on the motility of keratinocytes. As both interleukin-1 alpha and interleukin-8 provoke proliferation of keratinocytes, it is not unreasonable to propose that these two cytokines play a profound role in the enhancement of keratinocyte proliferation as a result of He-Ne laser irradiation. Our findings provide further evidence of enhanced wound healing at the cellular and molecular level as a result of the He-Ne laser.

Lens coatings enhance the lens performance of your glasses whether you wear single-vision, bifocal, or progressive lenses.
