Article: Weak or tight muscles can worsen your posture and fail to properly support your neck. Working on these may reduce the chance of the neck pain recurring. Once you can perform these exercises without pain, schedule them every other day. The day off is important to give your muscles time to rebuild. Stand against a wall or doorjamb. Place your feet about 3 inches (7.5 cm) out from the base of the wall. You may sit against a straight-backed chair instead, if it has a headrest. Take advantage of this when you have a moment during a long drive. Allow your chin to drop down toward your throat. This should stretch the back of your neck, and tighten the small muscles around your throat. Feel the large muscles on the front of your neck. If they are tense, lift your head again and lower your chin more slowly. The large muscles should stay relaxed, while the small muscles between them should tighten. Without raising your chin, move your head back so it touches the wall. If this causes pain, pull your head back as far as you can without pain. This is a sign of forward head posture, which you can correct with other exercise and lifestyle changes. Hold this position for ten seconds, then relax. Repeat this ten times, then stop. You can perform this exercise several times a day. After you practice this exercise, you may not need to have a wall or headrest behind you. Here's one final set of exercise that can strengthen your neck and nearby muscles. While you can't try this one on the go, some people find it easier than the exercise above:  Lie down on a firm surface, with a rolled up towel supporting your neck. Gently bring your chin down toward your throat. Keep the back of your head against the floor, and the back of your neck against the towel. Repeat several times. If you can do so without pain, repeat this same nodding motion while lifting the back of your head off the floor. Do not lift your neck off the towel.

Problem: Article: RGP lenses tend to be slightly less popular than soft lenses for a number of reasons, but there are many areas in which RGP lenses excel. An RGP lens will have the following benefits for most contact lens users:  Sharper vision than soft lenses provide Better visual clarity for some users with astigmatism Preferable for some users with presbyopia who require bifocals or multifocals Better fit and clarity for users with Keratoconus (cone-shaped cornea) Preferable for individuals who need contact lenses after refractive surgery Can be used for ortho-k procedures, in which lenses are worn at night to reshape the cornea Though RGP lenses are preferable for some users with specific needs, there are also some down sides to these lenses. Some users report that RGP lenses may have the following disadvantages:  They take longer to get used to and may be less comfortable. They will need to be worn regularly to become comfortable for the user (they can even become uncomfortable after a week of not wearing lenses). There is a greater risk of RGP lenses becoming dislodged during physical activities due to the smaller size of the lenses. There is a higher risk of discomfort or corneal abrasions due to the increased chance of dust/debris getting lodged under the lenses. They require greater care and maintenance than soft lenses; however, they tend to last longer, which may save you money in the long run. If you're on the fence about soft vs. RGP lenses, you may want to consider trying hybrid contact lenses. Hybrid lenses are made with a rigid, gas-permeable center but have a soft ring around the RGP component. This gives you the comfort of a soft lens while meeting the specialized needs some users have for a rigid lens.  Hybrid lenses can be used to correct nearsightedness, farsightedness, astigmatism, age-related loss of close-up vision, and keratoconus. Many users who need rigid lenses find that hybrid contact lenses are much more comfortable and easier to wear.
