Covid-19 prevention demands us to wear masks most of the time. It is crucial for the safety of our health, but it comes with a problem for people who wear eyeglasses. It causes fog on their eyeglass lenses and interferes with clear vision. Anti-fog coating for eyeglass lenses is an effective way of keeping the potentially dangerous fog away from eyeglass lenses.

Some other activities that allow for the fog to appear on our lenses include:

l Working out in a gym

l Exercising and playing sports

l Opening a steamy dishwasher or a warm oven

l Transitioning from a cold environment to a hot one

l Taking a warm bath

l Sipping a cup of a hot beverage

l Cooking over a hot stove

Anti-Fog Coating

Anti-fog coating on your eyeglass lenses eliminates the problem of fogging by preventing the condensation of moisture on eyeglass lenses. It is not restricted to the material of the eyeglass lenses and can be applied to polycarbonate, plastic, photochromic, high-index, and other kinds of eyeglass lenses.

Before the lenses are cut to fit into the frame in an optical lab, they are applied with anti-fog agents (chemicals) that minimize surface tension. It helps the water on the lenses to take the form of non-scattering films instead of droplets.

If you do not face the problem of fogging on a continual basis, you also have the option to get an optifog activator. It is a liquid with anti-fogging properties, and you can apply it to both sides of your eyeglass lenses and wipe them with a microfiber cloth. This will spread the liquid on the whole lenses and will keep them fog-free for up to seven days. Different anti-fog sprays and pastes are also available that work in the same way. You can use most of these products for mirrors, windows, and face shields as well. 

Different Anti-Fog Options

There are many different anti-fog coating options that you can opt for for your goggles, sunglasses, or eyeglasses. The different options cater to all budget levels, and it is better to evaluate your environment and requirements before making a purchase. If the atmosphere you live or work in is plagued with lens fogging, you should go for premium anti-fog solutions. 

Whether you are purchasing factory-coated anti-fog eyeglass lenses or an anti-fog spray, paste, or liquid, you will come across many different brands offering them. It is vital to read up on each and the pros and cons they offer. Eyeglasses that have an anti-reflective coating on them should not be applied with anti-fog liquids of some brands.

Anti-fog coating for eyeglass lenses is great for all eyeglass wearers, especially professionals that are engaged in professions that face emergencies, such as doctors, firepersons, and security workers. A blurred or fogged vision is also not good for the health of your eyes and can cause headaches. People who live in colder climates face eyeglass fogging issues and can benefit from anti-fog coating to a great deal.
