Nursing Tips – Contact Lenses – What You Should Know
Ophthalmologists (MD or DO) are eye surgeons who study and treat eye diseases and may also perform the functions of optometrists; optometrists (OD) examine the eyes, diagnose and treat vision problems, and prescribe glasses and contact lenses and, in most states, can also prescribe medications; opticians grind and dispense glasses and, in some states, dispense contact lenses. With a contact lens prescription in hand, it is possible to buy your contact lenses in stores, on the Internet, by phone or by mail. Among the many types of lenses you can buy are: Novelty, Colored, Crazy, Halloween, Special Effects, Theatrical, Costume, Scary, Glow-in-the-Dark, Wild Eyes, Mirrored, Black, White and Red.
All corrective contact lenses must have a valid prescription from an ophthalmologist or optometrist. Be careful when buying cheap contact lenses, they may not be of the quality you want; Discounted quality contact lenses are the most desirable.
Soft lenses also come as disposable products, meaning they are used once and discarded, or as planned replacement lenses. Extended wear contact lenses are worn overnight or continuously, for one to six nights or up to 30 days. Soft contact lenses are made of soft, flexible plastics that allow oxygen to pass to the cornea.
There are two general categories of contact lenses: soft and rigid, gas permeable. The length of continuous lens wear depends on the lens type and your doctor’s assessment of your tolerance to nighttime wear. Some doctors prescribe disposables as planned replacement lenses, which are removed, disinfected, and reused before being thrown away.
Newer soft lens materials include silicone hydrogels to provide more oxygen to the eyes. In some models, each lens corrects for near and far vision, and in others, one lens is for near vision and the other is for distance. There are extra-thin soft lenses on the market for very sensitive people.
While the ability to retain water increases the oxygen permeability of soft lenses, it also increases their fragility ratio. People who have good distance vision but need help reading can get a monovision reading lens for one eye.
Check how long the online provider has been in business before you buy. Beware of attempts to substitute a brand other than the one you want when buying contact lenses. When you receive your order, if you believe you have received an incorrect contact lens, please consult your doctor or eye doctor immediately; do not accept any substitution unless approved by your ophthalmologist.
Rebates may be available through the seller, the manufacturer, for first-time contact lens wearers, and for individuals who purchase lenses and undergo an eye exam. You can buy contact lenses from an ophthalmologist, on the Internet, in an optician or in a warehouse club.

Buy your contact lenses from a provider that you are familiar with and know is trustworthy or who knows their name. Always ask what rebates are available. Before buying online, check for testimonials on the online provider’s website.
To make sure your eyes stay healthy, you should not order lenses with an expired prescription or stock up on lenses just before the prescription is about to expire; it is much safer for your ophthalmologist to re-examine you. A vision-threatening concern is Acanthamoeba keratitis infection, which is caused by improper lens care; The symptoms of this difficult-to-treat parasitic infection are similar to those of corneal ulcers. The most serious safety issue with any contact lens is night wear.
Long-term rigid lenses can cause unexpected and undesirable reshaping of the cornea. Replace your contact lenses as recommended by your ophthalmologist because they wear out over time. If your eyes become red or irritated, remove the lenses immediately and consult your doctor.
No matter which lenses your doctor prescribes, be sure to ask for written instructions and follow them carefully. If you plan to buy contact lenses, you should buy the best quality you can get, even at a higher price; You don’t want to skimp on quality when it comes to your eyes. It is becoming easier to shop online and shipping is often free.
