Yes. Some sunglasses at drugstores have a decal that claims 100% UV (ultra-violet) protection. In reality, they have 100% of the FDA minimum recommended UV protection, which amounts to only 70% UV protection. This is deceptive, but legal, unfortunately. The problem lies in the fact that UV light is known to contribute to cataract formation and macular degeneration, and therefore it is important to block 100% of these harmful rays. We should buy sunglasses is to protect our eyes 100%.

Possibly.There are several reasons that reading "cheaters" purchased at the drugstore can contribute to eye problems. First, they always have the same prescription in each lens, and most people require a different power in each eye. Therefore one eye will be over- or under-corrected, leading to focusing disorders. Second, drugstore glasses never include correction for astigmatism, which nearly everyone has. Astigmatism blurs both distance and near vision.

There is a benefit to wearing UV protective lenses--wearing them may protect against cataract formation. Clear lenses with UV protection may offer greater protection than dark lenses because they allow the eyes to be exposed to more light. This causes greater constriction of the pupil which lets less light enter the eyes.

Yes, but only if the lenses have strong UV filters on them. Sunglasses help prevent squinting which contributes to crow's feet which is why wraparound lenses are the best. Be aware however, though UV lenses offer partial protection from damaging rays, they can't do the whole job so you'll still need to wear an SPF for the eye area.

Yes. The sun has damaging UV rays that can cause photokeratitis, pingueculae, and permanent retinal damage.

No. One is usually given a pair of special glasses to protect the eyes. There are no other harmful effects from the laser

No. Our eyes benefit from being used. If eyes feel “tired” or “strained” they should be rested, but normal activity won’t harm vision.

We cannot stress this enough...YES! You know how the sun's UV rays can harm your skin-wrinkles; premature aging and skin cancer are some of the dangers of unprotected sun exposure. The same rays that age and damage your skin can and will hurt your eyes as well. Strong sunlight, and artificial light from sources like welding arcs or tanning lamps can burn the surface of the eye, much like sunburn on the skin. Reflected sunlight (from the water, for example) is particularly dangerous.

Fluorescent light is perfectly safe for your eyes. Sometimes very old fluorescent fixtures or a malfunctioning fixture may cause the fluorescent bulb to produce a noticeable flicker. This flicker may be annoying, but it does not cause harm to your eyes.

Answer Patients are often concerned that changing pressure in an airplane can hurt the eyes after LASIK. This is not a problem. The truth is that the dryness of an airplane cabin is the greater concern. LASIK patients will need to moisturize their eyes frequently with artificial tears to prevent dryness and discomfort (perhaps every 15-30 minutes of air travel). We routinely have patients who fly the day after LASIK surgery. The eye is the most significant and precious part of our body.

There is evidence that sunlight exposure plays a role in certain eye diseases, such as cataract, macular degeneration, and eyelid cancer. It is a good idea to wear sunglasses with protection against ultraviolet light. Patients with or at risk for macular degeneration may also benefit from lenses which block blue wavelengths, such as yellow or amber lenses.

Answer: Basically we recommend that people who wear glasses should remove these during light therapy so that the UV component of the light which is important to our bodies is not filtered out. The UV component associated with the luminous intensity of full spectrum lamps is very small.

All of the clinical trials using the Light Visor(tm) received Institutional Review Board approval for human subjects. Safety is a major factor in receiving such approval. Furthermore, Bio-Brite commissioned a "hazard analysis" conducted by independent experts. It concluded that the energy emitted by the Light Visor(tm) is far below the threshold limit values recommended in national standards for photo-biological safety of lamps and lighting systems.

No, the level of ketosis achieved is very mild-just strong enough to protect you from losing muscle tissue. This mild level of ketosis has not been shown to cause harm to the body.

No! Viviscal contains no drugs, no hormones, no industrial by-products. Viviscal has been on the market in Europe for over half a decade, with only positive results, and is manufactured under GMP-certified conditions.

When speaking about digestive enzyme formulas, no. As active protein molecules, the enzymes do not accumulate in the body. They impart enzymatic activity that lasts anywhere from one to four hours and then they are eliminated from the body or the proteins are broken down and the amino acids are used for other purposes. As with any herbal or nutritional supplement, evaluation of amounts and over consumption should be determined on an individual basis. [back to top]

No, actually they are not. They are annoying, they itch, they eat blood like a mosquito, defecate on your scalp, and they are disgusting...but they are not harmful.

We have not tested it on animals. Head lice (for whatever reason) only live on humans. They can be carried or transmitted by animals but they cannot live on them for more than a few days. Since this is the case, we have not tried it on animals nor do we recommend it...you can try it at your own risk if you like.

Unfortunately, there is also a large amount of conjecture and opinion on the internet that has claimed that fluoride is dangerous. At therapeutic levels there has never been a published study that has been able show reliable repeatable results that demonstrate even a possibility of any harm. Many people find all of the negative opinions very confusing.

Currently, RESPeRATE is only available directly through InterCure, the manufacturer. You can order online or call 1-201-670-9999.

Sunglasses are regulated by the Food and Drug Administration (FDA) as medical devices. Domestic manufacturers and importers of sunglasses must register with the FDA, and are subject to numerous reporting requirements and good manufacturing practice inspections. The lenses must be impact resistant (not shatterproof) and the frames must be non-flammable.

Sunglasses that markedly reduce the UV-exposure of the eyes will reduce UV damage, such as cataracts. The best protection is achieved by a combination of UV-absorbing glasses and a shielding against light coming into the eyes from the sides. However, some sunglasses may not effectively block UV radiation and eye damage may occur.

Yes, all our sunglasses come with our own 1 year manufacturers warranty that covers defects in material and workmanship!

UV radiation from the sun can cause irreversible eye damage and can contribute to the development of skin cancer on the eyelid and on the surface of the eye.

Infrared rays are located just past the red portion of the visible light spectrum. While some experts believe that infrared light can be harmful in certain situations (such as being near large bodies of water or at high altitudes), most feel that the sun's infrared rays do not pose a danger to the eyes.

Not necessarily. While expensive sunglasses are usually high quality, you can also get a good pair for under $20 if you're a careful shopper. Just make sure to check that they provide adequate protection from UV light and are free of distortions. You can also take them to your eyecare professional to have the lenses metered to determine the amount of UV that passes through the lenses. That way you can be sure that you are getting the most from your sunglasses.

Children are at particular risk because they're in the sun much more than adults, and their eyes are more sensitive as well. UV damage is cumulative over a person's lifetime, which means you should begin protecting your child's eyes as soon as possible. Most parents would not allow their children to go outside without shoes, yet many seem unaware of the need to protect their children's eyes.

When a lens is polarized, it blocks scattered wavelengths of light, reducing and absorbing multiple reflections from other surfaces by canceling light that vibrates in one plane. Polarized lenses are very useful for activities on the water such as boating and fishing.
