Visit your optometrist regularly to check for visual impairments or diseases that may harm your overall eye health. If you have blurred vision, nearsightedness, or farsightedness, you might need either corrective eyewear or surgery. See your doctor based on age, health, and risk of eye problems. These are factors that will determine how often you should see your eye optometrist. If you are experiencing any difficulties with eyes, visit an optometrist as soon as you can as earlier treatment leads to better results. Check your visual acuity to determine if you will need prescription eyewear. Get screened for glaucoma, which is damage to your optic nerve. If left untreated, it will get worse over time. You might need glasses to improve your vision if you have either nearsightedness or farsightedness. In both cases, corrective lenses will either counteract the increased or decreased curvature of your cornea or the length of your eye. Eyeglasses are the most accessible and safest route to correct problems caused by vision impairment. You can get a range of eyeglasses: bifocals, trifocals, progressive lenses, reading, and driving glasses. Contact lenses are a popular choice as well. They are worn directly on your eyes and come as hard, soft, extended wear, disposable, and rigid gas permeable and bifocal. The most important factors in choosing eyeglasses or contact lenses are safety and lifestyle choice. There are several different types of surgery to choose from if you prefer not to get corrective lenses. These surgeries have become routine over the past two decades and are considered relatively safe for fully developed eyes. A doctor uses a laser to reshape the cornea. A laser-assisted in-situ keratomileusis (LASIK) surgery removes layers from your cornea and is repositioned to help you attain your desired level of vision. It is painless, immediate, and does not require a long recovery period. A laser-assisted subepithelial keratectomy (LASEK) is a procedure that reshapes the cornea's outer layers and changes its curvature to improve vision. Compared to LASIK surgery, LASEK surgery takes longer to recover from, may be more painful, and is more complicated in post-surgery recovery, but still a very successful procedure. Photorefractive keratectomy (PRK) is similar to LASEK surgery, but instead of the cornea, it's the epithelium that gets reshaped. Recovery includes wearing a bandage contact lens for a few days. An intraocular lens (IOL) implant is surgically implanted into the front of the eye's lens. Implants are not a popular treatment option at this time. Conductive keratoplasty (CK) uses radiofrequency energy to apply heat to the cornea. The biggest drawback to this procedure is that the results are not permanent. Side effects of refractive surgery include visual side effects, under or overcorrection, dry eye, infection, corneal scarring, and vision loss.

Q: In the event that your computer crashes permanently, you'll want to have a backup of your images. Copy your photos and paste them in a separate external hard drive, or upload them to an online cloud service. Popular online storage options include iDrive, pCloud, and Flickr. You can also use a general storage service, like Dropbox or Google Drive. Back your images up online and on an external hard drive to completely ensure that nothing happens to your images. Photographs take up a ton of space on a computer and you may not go through your images very frequently. To save storage space, get an external hard drive or flash drive and move your images to the new drive. Label the drive with a piece of tape and a marker so that you can easily find your images in the future. Whenever you want to look at your photos, plug the hard drive into the computer. If you only have a few hundred images, you can keep your images on a 16-32 gb flash drive. If you have a large number of photographs, get a standalone hard drive. If you have thousands of images, a 250-500 gb hard drive should provide plenty of space. A terabyte can hold roughly 1.5 million videos if you need to store a massive number of images. Leave your organized folder on the desktop if you want to easily access your photos whenever you want. You can also leave the folder in the "Photos" folder on your hard drive. If you have a specific file location where you store other media, you can also keep your photos there. If your computer ever crashes and you lose the photos on your computer, copy your backup folder and put it on your new computer when you get one.
A: Backup your images online or on a separate hard drive. Store the images on an external hard drive to save space. Keep a copy on your computer to easily access your images.

Article: By dehydrating your food, you take all of the liquids out. Once fully dehydrated, it's very difficult for bacteria to form, creating a food that can last for weeks or months without refrigeration. The content of the food, including fiber content and calories, stays the same with dehydrating (except for a loss of Vitamin C in some foods because of its solubility). With a food dehydrator, available at some grocery stores and at many places online, you can preserve fruits, vegetables, and meats. If you don't want to buy a dehydrator, you can also get the same effect from a low-temperature oven. Use the oven on the lowest possible setting, place your food on a non-stick pan, and use a small fan to keep the air circulating and prevent any moisture buildup. The process takes all of the liquid out of the foods, preserving it in a new, chewier form. Once dehydrated, you can store these foods without refrigeration for weeks. Dehydrating is particularly good for backpacking trips or other times when you need to carry your food with you. . Smoked meats have been a way for people to preserve food for thousands of years. The kinds of wood for the fire and the spices you put on the meat itself can create an array of delicious flavors on the meat. There are two kinds of smoking hot and cold. The differences are as follows: When you smoke meat using the "hot" method, you are cooking it at a low temperature (150 degrees Fahrenheit and up) for a long time. The "cold" method, on the other hand, is at less than 100F (37.8C) and is not really meant to cook the meat at all, but rather to seal the meat enough so that bacteria cannot grow in it. This method works particularly well if you're planning to cook the meat at some other point in the future. . Like smoking, curing is a process that has been around for thousands of years. The process involves using salt to leach the water out of meat, essentially dehydrating it. There are two main ways of curing meats: Dry curing involves rubbing the meat with salt and sodium nitrite and other spices of your choosing. The meat is then typically hung to dry. For safety, it's best to purchase a prepared mixture of salt and nitrate -- the amount should be about 1 teaspoon per 5 pounds of meat, but follow any directions on the mix that dictate amounts. Wet curing or brining also uses salt, but in a liquid solution. Meat is placed into a "brine" made of water, salt, sodium nitrite, and other spices to cure. The typical mixture is about 1 cups of kosher salt per gallon of water.
