There are two types of general contact lenses. Soft lenses and rigid gas permeable lenses are the two types of lenses. The rigid gas permeable is also known as RGPs.
Soft contact lenses are easier to wear because they are more moveable than that of RGPs. This makes them more comfortable to have in your eyes. The soft lens also allows oxygen flow freely to your cornea leaving your eyes feel better.
Rigid gas permeable contact lenses are sturdier and give you better sight making things look clearer. They have a longer life expectancy than that of a soft lens because of their durability.
The soft lens and rigid gas permeable both come in a disposable lens. The more popular of the two for disposable contacts is the soft lens. A disposable lens can have a life of seven to thirty days depending on the type and brand of the contact. However, disposable contacts are usually given to those that wear soft contact lenses.
There is also another category of lenses for those of you have a busy lifestyle and need your contacts almost all of the time. They are called extended wear lenses. These lenses are soft contact lenses because of the high demand of oxygen your cornea needs. There are however, a few RGPs that can be worn as extended wear contact lenses.
There is one last category of contact lenses. These are known as specialized contact lenses and there are two of these. Orthokeratology-K, which is known as Ortho-K, helps to change the curve in your cornea helping them with temporary improvement with how your eyes see objects. Ortho-K is not a permanent fix. Without the Ortho-K lenses as a treatment your eyes would still and always keep the curvature of the cornea.
The second type of specialized contacts is decorative contacts. These contacts change the color of your eyes. They are also used for Halloween to make your eyes look creepy or weird to go along with the theme of your costume. These contacts do not help or change any type of eye problem you may have., but they still have the same risk factors as corrective lenses.
Anyone who wears contact lenses knows there is everyday care for your contacts and for your eyes that you should follow. Always have a pair glasses around to fall back on just in case you would lose a contact or the contact would start irritating your eyes. Washing your hands before putting your contacts in helps with reducing infection.
Another thing to do that can help ensure the safety of your contacts and eyes is to clean out your contact case every time lenses are out of their case. The cleaning of your case will help keep bacteria from growing where you store your lenses. These are just a few important ways to care for your contact lenses and especially your eyes.
Before getting any type of contact lens you need to see your eye doctor for an examination and a prescription for lenses. This will help you decide what types of contacts are best for you.
A sty is a pimple or abscess that forms in either the upper or lower eyelid. The medical term for sty is hordeolum(say HOR-dee-oh-lumm) and it is an infection caused by bacteria that normally live peacefully on the eyelid skin surface.
Some of thee germs get trapped along with dead skin cells inside crypts along the eyelid margin. Stys are usually superficial and plainly visible. Occasionally they can reside deeper within the eyelid.
This common infection or inflammation results from blocked glands within the eyelid. When the gland is blocked, the oil produced by the gland occasionally backs up and extrudes through the wall of the gland, forming a lump, which can be red, painful, and nodular. Frequently, bacteria can infect the blocked gland, causing increased inflammation, pain, and redness of the eye and even redness of the surrounding eyelid and cheek tissue.
The lump can point externally (outward) or internally (inward). Frequently, the lump appears with a visible whitish or yellowish spot that looks much like a large pimple.
An external sty starts as a pimple next to an eyelash. It turns into a red, painful swelling that usually lasts several days before it bursts and then heals. Most external stys are short-lived and self-limiting.
An internal sty(on the underside of the lid) also causes a red, painful swelling, but its location prevents the familiar whitehead from appearing on the eyelid. The internal sty may disappear completely once the infection is past, or it may leave a small fluid-filled cyst or nodule that can persist and may have to be opened and drained.
Stys are usually caused by staphylococcal bacteria, which often live right on the skin surface. Truth be told, our bodies are coated with billions of friendly bacteria that coexist with us. When the conditions are just right the bacteria feast on dead cells and other debris, resulting in the tender pimple.
Good hand and facial washing may prevent styes from forming or coming back.
The eyes contain many small muscles, and there is no doubt that eye exercises can do little harm to your eyes, but can they actually be of benefit?
A New York ophthalmologist called Dr William Bates, developed a series of eye exercises to improve eyesight without resorting to lenses or surgery. Dr Bates felt that many eye problems had their root causes in stress, tension and laziness of the eye and he thought that because of these causes, the eyes could be treated without correction such as lenses, spectacles or even surgery. Dr Bates’ methods were first devised at the beginning of the 20th century, but many people still practice them today.
Dr Bates’ theory revolved around the notion that the muscles of the eye became fixed on a scene causing strain to the eyes. Dr Bates felt that the eyes could be re-trained to relax and improve the link between the optic nerves and the brain.
Dr Bates’ theories have been largely ignored by the world of medicine. However, many people around the world have claimed remarkable improvements in short sight, long sight, astigmatism, squints and lazy eyes using these methods. Even young children are able to practice the exercises and people with normal vision may improve concentration, reading skills and co-ordination by following the routines suggested by Dr Bates.
In essence, you can expect to perform some simple exercises for about half an hour a day. These can involve some of the following:-
To rest and relax your eyes, sit comfortably in front of a table, resting your elbows on a stack of cushions high enough to bring your palms easily to your eyes without stooping forward or looking up. Close your eyes and cover them with your cupped palms to exclude light, avoiding pressure on the sockets. Breathe slowly and evenly, relaxing and imagining deep blackness. Begin by doing this for 10 minutes, two or three times a day.
Relax and keep the eyes mobile. Stand up and focus on a distant point, swaying gently from side to side. Repeat 100 times daily, blinking as you sway. Blinking cleans and lubricates the eyes, which is especially important if you spend a lot of time in front of a computer.
You may be asked to have a ‘colour day.’ Choose a colour and look out for it throughout the day. When you see it, be aware of the colour rather than the form. For example, if it’s a red truck, experience the shade of red, not the truck.
Why not try some of these exercises yourself?
See Clearly Method
The See Clearly Method is another popular series of exercises and training to help with vision correction. Similarly to the Bates’ method, you are required to do 30 minutes of eye exercises a day to strengthen and enhance the flexibility of the eye’s muscles. This would usually involve making the eye change it’s focus from near to far for example. One simple way of doing this would be to hold a small object in your hand and slowly move it away from your face, ensuring that your eye follows the object and retains focus upon it.
One exercise which is know as “tromboning” has you hold a small object again, starting at arm’s length. Then you need to breath in and move the object slowly closer to your face, until it touches your nose. You are then required to breath out, looking at the object as you again move it away from your face. Hence the notion of “Tromboning”.
The See Clearly Method also employs a number of techniques which are aimed at accelerating progress or improvement. For example, there is a technique referred to as the “blur reading” technique, which asks you to turn a magazine upside-down at a distance where the words are not distinct. Then, you are supposed to choose one word and focus your attention around it, to see if you can identify any of the letters.
As with the Bates’ Method, the eye exercises suggested in the See Clearly Method are certainly worthy of a go to see if they help you at all.
All in all, LASIK eye surgery is relatively less complicated than other kinds of surgery. However, if carried out in an imprudent fashion, LASIK eye surgery may cause an irreversible damage that would make you repent for the rest of your life. Therefore it is gravely necessary to choose the best surgeon available. There are various ways that help you locate and choose the best surgeon in your vicinity.
Advertisements can be a viable source for finding a LASIK surgeon. However, there is a caveat. Some ads provide a detailed explanation of the inclusive features of their package, while some tout discounted prices but dont give out the details. Not all people are eligible for discounts, and hence an ad should not be the only criterion for choosing a LASIK surgeon. Experience is what counts the most, so choose a surgeon with plentiful experience.
Leading LASIK surgeons recommend that you should choose a doctor who is a fellow of the American College of Surgeons. Alternatively, you may visit the American Academy of Ophthalmologys website at www.aao.org, where you could carry out your quest for an experienced LASIK surgeon. Another valuable resource for LASIK candidates is the website of the Eye Surgery Education Council (ESEC) www.lasikinstitute.org. The website offers useful tools to locate a surgeon in your neck of the woods. Asking for a referral from your regular optometrist is also a viable option.
It is imperative that experience be the number one factor governing your choice for a LASIK surgeon. Having, acquired a list of available surgeons, you can narrow down on the basis of experience. There is no dearth of LASIK surgeons, but the point is that you want the best surgeon for your eye surgery. Just go through the recommended resources and you will surely find what you need.
There are several LASIK benefits, which can be easily realized by going in for an experienced eye surgeon. It is necessary that you weigh the pros and cons before going in for an eye surgery. And much to your relief, as far as LASIK is concerned, the benefits far outweigh whatever minimal risk is involved. LASIK is by far the most preferred procedure when it comes to eye corrective surgery. LASIK benefits typically include:
- Clear natural vision
- Need for glasses or contact lenses is eliminated
- It simply widens the horizon for recreational opportunities
- Quality of vision is better than that with glasses or contact lenses
- Greater self-confidence
- More career opportunities
- Enhanced natural appearance in many cases
- No risk of infection or inflammation generally associated with contact lens overuse
The above are only a few major positives that come out of the LASIK procedure. LASIK has superlative scientific technology at its disposal. High-precision lasers, computer-controlled tracking devices, all enable the surgeon to perform the operation with ease and finesse. Furthermore, complication rates of a meager 1% to 5% strengthen the belief that LASIK is a completely safe procedure.
LASIK does not require the removal of the corneal surface tissue, and this substantially reduces the post-operative pain. In general, the visual acuity is restored within a day or two. Other procedures like PRK may require a week or so for sharpness of vision to be restored. LASIK surgery also possesses a greater stability. That is, the corrected vision lasts permanently, provided a complication does not arise during the procedure. Moreover, most patients are able to pass the drivers license test without the aid of glasses or contact lenses.
If you are in quest for a corrective eye surgery, LASIK is sure to satisfy your needs. All you need to do is look for an eye surgeon who is highly skillful and qualified.
