Different Types of Sunglasses

In addition to protecting the eyes from UV rays, sunglasses also have their respective functions based on the type of lens. Here are the types of glasses that you can choose according to your needs:

1. Glasses with polarizing lenses

Glasses with polarized lenses have a function to reduce the glare caused by the surface of the water when exposed to reflected light. This type of glasses is very useful for driving during the day.

2. Glasses with polycarbonate lenses

The polycarbonate material embedded in the lens of the glasses has a function to protect the wearer who likes to do team sports, such as volleyball. The reason is because glasses with this type of lens have strong resistance to impact.

3. Glasses with lenses to block blue

Glasses with this lens function to see distant objects or objects that are blocked by fog. This type of glasses is usually used by hunters, sailors, pilots, or people who like skiing.

4. Glasses with photochromic lenses

These are glasses whose lenses can adjust the amount of light exposure. For example, when exposed to large amounts of light, glasses with this type of lens will turn dark. On the other hand, at night, when the sun is no longer there, the lenses of these glasses will become brighter.

5. Glasses with gradient lenses

Glasses with gradient lenses are divided into 2 types, namely single and double gradient lenses.

A single gradient lens is a lens that is darker on the top than the bottom. This lens is able to reduce glare, so the wearer can see objects clearly. This type of glasses is good to use while driving.

Meanwhile, a dual gradient lens is a lens in which the bottom and top are dark, while the center is lighter. You can choose a dual gradient lens if you often do water-related activities, such as sailing.

How to Choose the Right Sunglasses

Regardless of the type of lens, here are general guidelines for choosing the right sunglasses:

  • Choose sunglasses whose lenses can block 99–100% of UVA and UVB rays. This can usually be seen on the sticker or label on the glasses.
  • Choose sunglasses with large, circular frames, to best cover the eyes and the surrounding area.
  • Choose sunglasses that have a dark color or lens
  • Choose sunglasses with plastic lenses because they are more impact resistant.

In addition, it should also be remembered that there are no sunglasses that can protect the wearer from light that is too bright and has strong intensity, for example when viewing a solar eclipse.Therefore, if you are often exposed to strong light during daily activities, such as welding, you must wear special equipment to protect your eyes.

If you are having trouble deciding on the best sunglasses for you to choose, don't hesitate to consult a doctor about this. That way, the doctor can recommend sunglasses that suit your condition.
