Brand-name sunglasses are expensive and not suitable for all budgets. If you are looking for cheap sunglasses, you will be surprised how many styles you can find at an affordable price.

Cheap sunglasses include styles that cost less than $30. If you want to know how they compare to more expensive sunglasses, it's a question of build quality and functionality-and you get what you pay for. Having said that, there are many fashionable and high-quality cheap sunglasses.

If your budget is limited, this cheap sunglasses buying guide can help you find a good pair of sunglasses.

Your most common type of lens in cheap sunglasses are polarized lenses. This quality reduces glare and protects your eyes from UV rays. They make the image look clearer and may reduce eye strain. However, one of the disadvantages of polarized lenses is that they are not the best choice for viewing LCD screens.

Sunglass lenses may have UV, mirror, anti-reflective or scratch-resistant coatings. The following are the differences between them:

As far as cheap sunglasses are concerned, only some sunglasses have these coatings. In addition, Healthline stated that many cheap sunglasses do not meet the protection standards recommended by eye care professionals.

Sunglasses come in a variety of lens colors, some of which are more conducive to certain types of activities.

Gray and black lenses are popular in most outdoor activities. Amber lenses provide better depth perception and are often worn by golfers or anglers. The yellow lens, which is popular with cyclists, provides a high level of clarity and filters out blue light.

There are also blue lenses, suitable for watching spectator sports. Rose-colored lenses help the eyes adapt to the sharp contrast in the environment. They are the first choice for winter driving or winter sports.

Cheap sunglasses are usually made of plastic, polycarbonate or metal parts. Like other types of glasses, they are held together by small screws at the hinge.

The construction quality of cheap sunglasses is lower than that of high-end sunglasses. They are generally not that durable and will not be very good if they are subjected to heavy handling.

Although they may not last as long as more expensive sunglasses, this is not always the case. Good-maintained cheap sunglasses, especially those kept in a protective sunglasses case, can last for 5 years or more.

Some cheap sunglasses have three numbers printed on them, representing the size of the eyes, the width of the bridge of the nose, and the length of the temples. They can help you find the right size and best-fitting sunglasses.

If you are not sure about your size, you have a few options. The manufacturer may provide a compatibility chart for measurement, or if you have prescription glasses, please refer to the size printed on the temples.
