If you have vision problems then you know that there is only one good solution for that besides the expensive LASIK surgery: glasses the Woodlands.
However, you need to take note that in choosing the perfect pair of lenses, you need to know some of its basics like how to choose the ideal frame shape that complements the shape of your face, as well as the common lenses coatings you can have on your eyeglasses.
If you are considering having a new pair of lenses, then read this and you might want one or two of these coatings!
1. scratch-resistant coating – the eyeglasses lenses that you see are all not scratch-proof. This can cause inconvenience on your side as your eyeglasses may develop and accumulate more and more scratches especially when you put on AR (anti-reflective) coating, which may render your lenses more vulnerable to scratches. However, by putting and treating your lenses with a clear scratch-resistant coating, front and back, you can reduce the number of scratches your lenses will have from occasionally cleaning them with rough clothes. This coating makes the lenses more durable.
Most lenses today including high-index lenses are made of Trivex and polycarbonate already has this scratch-resistant coating. However, take note that this coating is mostly optional so you need to inform your optician that you want this coating on your lenses.
2. Anti-reflective (AR) coating – also known as the anti-glare coating is a multi-layer coating that disables the lenses to reflect light, front and back. This AR coating provides two advantages: one, because it eliminates reflections, people can focus on their eyes without the distracting light reflections; and two, it helps in reducing UV light absorption whether coming from the sun or digital screens.
3. ultraviolet (UV) coating – this is an invisible dye that effectively blocks UV lights and prevents harm that they cause to your eyes when you are oftentimes facing light screens. Prolong exposure to UV lights may cause retina problems, cataracts, and other eye conditions. This is ideal for people whose works involve facing the computer screen every day. Take note that photochromic lenses also block UV rays without the need for UV lens coating or treatment.
4. Anti-fog coating – if you are working in a ventilated office with a full AC, and at the same time you wear eyeglasses, then you probably have experienced the discomfort that fogging on your lenses brings. Moreover, fogging also happens when you sip a hot beverage or breathe while wearing a face mask. While some people see this as a “convenience” issue, this also poses hazards and safety issues. Lens fogging can be dangerous when you are driving or in times of emergency.
The anti-fog coating is designed to eliminate the condensation on lenses which causes the lens fogging. With this coating, your lenses stay clear even transitioning from colder to warmer (or vice versa) environments.
Now that you know the common lenses you can coat your lenses, it is now time to go and purchase a new pair of eyeglasses!
