When the weather warms and families come out to play, they're not the only ones gearing up for a great summer vacation. Scammers slither out in force and they have some pretty incredible ways of separating would-be vacationers from their money and ruining plans.

We have combed the web to find the scams that readers are most likely to encounter. There are also some "iffy" practices, whether or not they are actual scams. But be alert and summer play time will be a lot more enjoyable. These suggestions are taken from the Federal Trade Commission, The Better Business Bureau, Experian and others reliable sources:

Travel offers

Avoid or at least be cautious with "discount travel" companies and offers from third-party companies. Some push consumers to be impulsive, then take a credit card or debit card number and may either not provide the level of service promised or not come through with service at all. If you're not familiar with a company, look for reviews, warnings and other information, or vet them with a consumer protection source like the Better Business Bureau. Try a web search of the company's name and the word "scam" to see if anything interesting or disturbing appears.

"Free" vacations offers are quite apt to be a money-dropping illusion. If you're asked to pay a big fee up front or provide your credit card number, it isn't really free, is it? Keep your credit card digits to yourself in this case.

The FTC says if you get cold-called with what seems like a good offer, check with the attorney general's office in the company's home state and with local consumer protection agencies. Google them, too. If they won't wait for you to check them out, you don't want to do business with them.

The FTC says a travel club that pressures you to sign up "right now" or miss out is one you should walk away from right now. "Travel clubs often have high membership fees and limited choice of destinations or travel dates."

Responding to robocalls that kick off vacation planning are a bad idea and "almost always illegal if you haven't given the company written permission to call," says the FTC.

The U.S. Department of Transportation lists approved public chartered flights. Look it up. Also, check the charter's reputation with local travel agents or ask the American Society of Travel Agents. Read online reviews from another source. Again, check before you pay. If the charter doesn't like your delay, tough.

Phishers are everywhere. One scam involves calling or emailing with the good news that you've won airline points. You need only verify your eligibility by offering personal information or a credit card number. Says BBB, "If you do provide the requested information, no additional points will be rewarded, you will lose money and be at risk for identity theft."

Accommodations

Thousands of travelers use Airbnb with great results, but some rental services don't deliver as advertised. Those services typically offer great discounted rates on beautifully portrayed (in word or photo) properties, and the "owner" insists on immediate down payment, probably by bank wire. Says Experian, the traveler finds the "property in a deteriorated state, or they find the property is owned by someone else and isn't available for rent at all." It's a good idea to look up reviews on a property, though that's not a guarantee you won't get burned.

To address this problem, Airbnb holds payment until after the renter checks in. And HomeAway has secure payments and guaranteed refunds. Meanwhile, Consumer Reports says to never pay for your vacation housing by wiring money or with money orders or cashier checks. They lack adequate consumer protection.

The Better Business Bureau notes how easy it is to copy photos online, so be aware what you see may not be what you get. Put the address of a hotel or rental property in Google Maps and see what the property at that address actually looks like and how it compares to the picture that made you swoon. The person on the other side of the transaction can wait until you do that.

Be leery of travel-booking sites that bundle airfare with hotels and offer you two prices for hotels, one which you can cancel and the other discounted but non-refundable. In some cases, it works like this: As you're ready to pay, you're told to call and talk to an agent to verify everything. The agent "runs the purchase" and tells you, sadly, that the cost of airfare, which was not fixed, went up. When you decide to cancel, she notes that she can cancel the airfare portion, but you are on the hook for the hotel cost because you selected the cheaper, non-refundable hotel rate and both transactions processed together. The dilemma then is whether to pay the higher airfare rate you would not have accepted when choosing the package or walk away from a hotel you paid for but you'll never see.

And once you have settled into your place, don't let your guard down. If someone slips a menu under your hotel door, ask the hotel if it's legit. Fakers happily answer your call, take your order, gather your credit card information and leave you with nothing but a bad taste in your mouth.

Foreign travel

If you travel abroad, take time to know the currency exchange rate for the dollar and don't make the exchange just anywhere. Some "street-based storefront currency exchanges" charge a higher rate, figuring foreign travelers won't know the actual rate. Experian says to use only commercial or government banks and financial institution currency exchanges or accredited currency exchange stores.

Don't be diverted from official taxi stands at airports and other transportation hubs. In France, for example, recently, a family was met by a "transportation official" at the entry point to the taxi line at an airport and was sent to a different door to get the cab itself. Thinking it was routine, they went to find themselves a short time later charged $200 for a $50 fixed-rate cab ride, with no way to fight back because they hopped in that cab voluntarily. That reportedly happens in multiple countries, so go through the designated door and find the correct line, then stay in it.

The BBB warns of a fake same-name bus service in Vietnam, where scammers use legitimate tour bus company names to defraud travelers. The result is poor or nonexistent service and money lost. You can also end up pressured to use a hotel with which the fraudsters have partnered.

In some big cities, someone on the street may hand you a "free" CD or a flower, then loudly demand that you pay for it. In other countries, you may be given a different "free" trinket, but the scam is pretty similar.

Some more advice:

Don't ever wire money or use a prepaid debit card to prepay a vacation. The experts warn you will probably get nothing for your money.

Watch for hidden fees. Always ask about mandatory resort fees, for instance, which may be assessed when you arrive and which can raise the cost of a hotel room considerably. One protection is to carefully read the fine print before you book.

Get all the details in writing, including not just those of the vacation, but the details of how to cancel, get a refund, what happens if there's a serious weather issue or you can't go because your appendix ruptured, etc.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
