A comparison between prescription sunglasses and clip on sunglasses

May 29th, 2010

The popularity of clip on sunglasses in the eyewear industry is to a large degree reasonable. It reflects people’s natural pursuit for savings because prescription sunglasses are usually considerably more expensive. In fact, prescription sunglasses and clip on sunglasses have both advantages and disadvantages. For instance, prescription sunwear is convenient because it eliminates the necessity to put on and take off the clip ons. Participating in an outdoor activity, a single pair of Rx sunwear will be enough for vision defected people. However, Rx sunglasses cost much more than regular Rx glasses, ordinary sunwear and even a combination of both. In addition, prescription sunglasses are unnecessary when the wearer enters an indoor environment because sunlight is absent. Using an expensive pair of Rx sunwear can thus be wasteful.

Meanwhile, we should also recognize that clip on sunglasses are not perfect, for they require probably frequent clipping and removing. But they are quite more affordable by ordinary individuals than prescription sunglasses. For most users, it is acceptable to clip on extra sunshade onto their regular Rx eyeglasses. Another benefit of using clip ons is that it is easy to get another pair if the old pair gets lost, scratched or even broken. The reason is that clip ons are separate and it is unnecessary to spend a lot of extra money on a pair of prescription sunglasses. Currently, clip ons come from the simplest styles to high end designer styles. This enables their wearers to enjoy various looks, which is the reason why many people keep more than one pair for different circumstances.

Nowadays, clip on sunglasses are available at mainly three types, magnetic clip-ons, magnetic flip-ups and true clips. Magnetic clip ons are usually polarized and can block out harmful UV rays and glare. Their magnetic feature makes them easy to use and just “click” into place. Nearly no effort is needed to snap them on. Magnetic flip-ups are also magnetic but they require a bit effort to put onto the frame. The benefit is that they do not require additional effort of removing and putting back. They will flip right up when UV protection is unnecessary. The third type is true clips, which have claws that hook to the regular frame. Of course, they are the most cumbersome to put on and take off.

Prescription sun glasses – A good choice

February 14th, 2010

Most of us must have the experience of looking for clip-on sun lenses worn over our normal eyeglasses when we go outdoors. In this case, a pair of prescription sun glasses will be a good substitute and a better choice.

The function of prescription sun glasses is equal to a combination of eyeglasses (or contact lenses) and a frame of sun lenses. The 2 in 1 prescription sun glasses make the outdoor activities more at ease. For example, for contact lenses wearers, it is not healthy and good to wear non-prescription sun glasses over the contact lenses to go to beach where aquatic activities may be watery.

Prescription sun glasses can be made based on virtually all the lenses prescription, it is almost the same as prescription eyeglasses. Single vision, bifocals and multifocals are all available for prescription sun glasses.

There are wide frame choices for prescription sun glasses. But not all the frames for non-prescription sun glasses are suitable for all the prescription sun glasses. For example, some wraparound styles are not suitable for prescription sun glasses, as the prescription lenses have optical centers to match the wearer’s PD.

Something special for prescription sun glasses is the polarization. Polarized prescription sun glasses add more reflective protection from water wave, concrete road and other places which easily reflect sunlight to the eyes.

Lenses for prescription sunglasses

January 1st, 2010

There is a wide choice for the lenses of prescription sunglasses. Most of the lenses materials are available for prescription sunglasses, such as glass, CR-39 resin and polycarbonate. The tints of lenses most frequently used are brown, yellow, blue, purple and green.

Yellow and brown prescription sunglasses are good for sports like golf and shooting. For fishing and hunting, wearers need sunglasses with polarized lenses to reduce the glare from water and mountain.

Another choice for purchasing a pair of prescription sunglasses is to choose the photochromic lenses. Photochromic is a patent technology owned by Transition. Photochromic lenses can automatically darken when wearer is exposed to UV rays from strong sunlight, and change back to clearer look when wearer is indoors. Photochromic prescription sunglasses are highly welcome, but still have some defects. They don’t darken enough inside the car while driving because windshield has blocked most of the UV rays. Another shortcoming is that the tint of photochromic prescription sunglasses is not ample in extra bright sunlight.

Optical experts suggest a combination of normal prescription eyeglasses and a frame of clip-on, or a pair of photochromic prescription sunglasses and a clip-on. This will suit a wearer under most of the lighting conditions.
