Contact lenses, like eyeglasses or LASIK, can correct our nearsightedness, farsightedness and astigmatism. While some people enjoy making a fashion statement with eyeglasses, others prefer their appearance without them. Contact lenses can achieve this without irreversible refractive surgery. Contact lenses can also provide a full field of unobstructed vision, which is great for sports. Contact lenses have been around for more than a hundred years. During that time, much advancement have allowed just about everyone to wear contact lenses. If you were told in the past that you couldn't wear contact lenses, odds are that's not true today. There are more convenient and healthy contact lens options than ever.
If you're new to contact lenses, your first step is to see an eye doctor.
The many types of contact lenses currently available can be grouped in various ways according to:
Until 1979, everyone who wore contact lenses removed and cleaned them nightly. The introduction of "extended wear" enabled wearers to sleep in their contacts. Now, two types of lenses are classified by wearing time:
Continuous wear is a term that's sometimes used to describe 30 consecutive nights of lens wear — the maximum wearing time approved by the FDA for certain brands of extended wear lenses.
Even with proper care, contact lenses (especially soft contacts) should be replaced frequently to prevent the build-up of lens deposits and contamination that increase the risk of eye infections.
Soft lenses have these general classifications, based on how frequently they should be discarded:
Bifocal contacts for astigmatism:- These are advanced soft contacts that correct both presbyopia and astigmatism, so you can remain glasses-free after age 40 even if you have astigmatism.
Contacts for dry eyes:- Are your contacts uncomfortably dry? Certain soft contact lenses are specially made to reduce the risk of contact lens-related dry eye symptoms.
Colored lenses:- Many of the types of lenses described above also come in colors that can enhance the natural color of your eyes — that is, make your green eyes even greener, for example. Other colored lensescan totally change the color of your eyes, as in from brown to blue.
Special-effect lenses:- Also called theatrical, novelty, or costume lenses, special-effect contacts take coloration one step further to make you look like a cat, a vampire, or another alter-ego of your choice.
Prosthetic lenses:- Colored contact lenses also can be used for more medically oriented purposes. Opaque soft lenses called prosthetic contacts can be custom-designed for an eye that has been disfigured by injury or disease to mask the disfigurement and match the appearance of the other, unaffected eye.
UV-inhibiting lenses:- Some soft contact lenses help protect your eyes from the sun’s ultraviolet rays that can cause cataracts and other eye problems. But because contacts don't cover your entire eye, you still should wear UV-blocking sunglasses outdoors for the best protection from the sun.
Hybrid lenses:- One brand of lenses features a GP center with a soft outer skirt, providing wearers with both the crisp optics of a rigid lens and the comfort of a larger, soft lens.
Scleral lenses:- Large-diameter gas permeable lenses called scleral contacts are specially designed to treat keratoconus and other corneal irregularities, as well as presbyopia.
Myopia control contacts:- Special contact lenses are being developed to slow or stop the progression of nearsightedness in children.
Finally, consider your "wish list" of contact lens features — colors, for example, or overnight wear.
When you and your ECP decide on the right lens for you, you'll be given a contact lens prescription. You'll be able to buy a supply of lenses from your ECP or from the many other outlets that sell contact lenses.
Caring for your contact lenses — cleaning, disinfecting and storing them — is much easier than it used to be.
A few years ago, you would have needed several bottles of cleaning products, and perhaps enzyme tablets, for proper care. Today, most people can use "multipurpose" solutions — meaning that one product both cleans and disinfects, and is used for storage.
People who are sensitive to the preservatives in multipurpose solutions might need preservative-free systems, such as those containing hydrogen peroxide. These do an excellent job of cleaning contacts, but it's very important to follow the directions for using them. The solution should not come into contact with your eyes until soaking is complete and the solution is neutralized.
Of course, you can avoid lens care altogether by wearing daily disposable contact lenses.
Trial and error often is involved in finding the perfect lens for you. People react differently to various lens materials and cleaning solutions.
Also, the correct "parameters" of your lens — that is, power, diameter, and curvature — can be finalized only after you've successfully worn the lens. This is especially true for more complex fits involving extra parameters, such as with bifocals or toric contact lenses for astigmatism.
If you experience discomfort or poor vision when wearing contact lenses, chances are that an adjustment or change of lens can help.
Today, more contact lens choices than ever are available to provide comfort, good vision, and healthy eyes. If your eyes or lenses are uncomfortable or you are not seeing well, remove your lenses and visit your eye care professional to explore available remedies for contact lens discomfort.

1. Know Your Frame Size
Glasses that don't fit right can be just as uncomfortable and awkward-looking as ill-fitting clothing. Selecting the correct size frames will ensure that you look and feel your best. Your frame size consists of three components: eye size, bridge size, and temple size.
2. Choose Glasses that Complement Your Face Shape
The right eyewear can enhance your appearance by highlighting your favorite features while minimizing any imperfections. Knowing which frames are the most flattering for your face shape will help you narrow down your choices when shopping for glasses online.
3. Pick a Frame that Fits Your Personal Style
Frame color, material, shape, and detailing all play an important role when it comes to eyewear styles. Brightly colored plastic frames give off a cool, youthful energy, whereas real wood finishes or neutral tones convey a sense of sophistication. Ehsan Optics (Shop Locations) haveclassic, trendy, hipster, sporty, retro, or something in between.
While outlandish or elaborately embellished frames may be fun to try on, if your everyday style is classic, you may have trouble matching your outfit with your eyewear. So, keep your wardrobe in mind when buying glasses online.
4. Know Your Prescription Type
Do you need single-vision or multi-focal (e.g. bi-focal, tri-focal, or progressive) lenses? Knowing your lens type beforehand will help ensure that you select the correct lens materials and that you enter your prescription information correctly.
5. Choose a Lens Material to Match Your Prescription & Lifestyle
There are three basic lens materials for prescription eyewear. Each has different price points and recommended use.
6. Select the Appropriate Lens Coatings
There are a variety of coatings that can be added to any lens. Understanding your options will help you make the right choices for your lifestyle.
7. Know Your Pupillary Distance (PD)
One of the most important parts of your prescription that doctors often forget to include is your pupillary distance (PD). Pupillary distance is just what it sounds like: the distance (in mm) between the pupils of your eyes. This measurement is important because it ensures that the center of your corrective lenses is placed directly in front of your pupils.
Be sure to ask your eye doctor to write down your PD if you're going to order glasses. Depending on whether you need single-vision or multi-focal lenses, your doctor may write your PD as one or two numbers. If you can't reach your eye doctor, we can help you determine your PD (Shop Locations).
8. Understand Your Prescription Information
Entering your prescription online is probably easier than you think. It's simply a matter of entering the correct numbers in the appropriate fields. Don’t worry if you do not see any numbers listed on your prescription for some fields, like "prism" and "base." Not everyone needs this kind of correction, so you can simply leave those fields blank.
Below are a few key terms you may need to know when entering your eyeglasses prescription online:
Many people choose sunglasses by how they look and feel. But the most important feature to consider is how well they shield your eyes from ultraviolet rays (high-frequency invisible energy emitted by the sun), as well as blue light (high-frequency visible light).
Chronic ultraviolet (UV) exposure is implicated in a range of eye conditions, including cataracts, benign growths on the surface of the eye, skin cancer on the eyelid and around the eyes and even melanoma of the eye itself. Blue light is particularly damaging to internal eye tissues and over time may permanently damage the retina, leading to macular degeneration.
Sun damage is cumulative, so the more time you spend outdoors with your eyes unprotected, the greater your lifetime risk. The good news is that it’s not hard to find affordable sunglasses that are fashion-forward and protective.
Everyone who spends time outside should wear sunglasses. That includes children (whose eyes are especially vulnerable to UV) and people who wear contacts (even if UV-treated, they don’t cover the whole eye). Sunglasses are a necessity for people who are sun-sensitive due to medications (such as tetracycline) or other reasons, and for those who have had cataract surgery, especially if they have an older intraocular lens that provides no UV protection. Light-colored eyes are especially vulnerable to UV. Even on overcast and hazy days, your eyes can be exposed to significant UV radiation.
Here’s more reason to wear a pair:
What to look for in sunglasses
There are no federal standards for sunglasses, and labels are inconsistent and confusing. A tag or sticker that simply says “blocks UV” or “UV-absorbent,” for instance, is meaningless because it doesn’t tell you how much UV is blocked. Better choices are sunglasses that claim to block most or all UV (“99-100% UV absorbent” or “UV 400,” for example), though there is no independent verification for this.
One way to be certain that your sunglasses are blocking most or all UV is to have an optician test them using a photo spectrometer (often called a UV meter). It’s a good idea to have old sunglasses tested, since some of the UV coating, if one was applied, can be lost over time through scratches and abrasions. An optician can also coat sunglasses, if necessary.
More general pointers:
Both clear glass and plastic lenses naturally filter out some UV light (polycarbonate plastic, in particular, blocks nearly all UV). But maximal UV protection comes from clear chemicals that are incorporated into the lenses during manufacture or applied as a coating.
Darker lenses don’t mean greater UV protection. In fact, unless darker lenses are fabricated to block UV, they can be more harmful than wearing no sunglasses, because they can cause pupils to dilate, allowing more UV to enter your eyes. Darker lenses do, however, block more visible light and minimize glare. They should be dark enough so you don’t see your eyes when you look in the mirror, but light enough so you can see curbs, stoplights, and stairs.
Colored lenses reduce visible light, but color has nothing to do with UV protection. Yellow, amber and orange lenses block the most blue light and enhance contrast, but can distort colors. Brown also blocks significant blue light. Gray and brown lenses produce the least color distortion and are good for all-around wear and driving. Green distorts minimally. Avoid blue-tinted glasses, which let in more blue light.
The larger the frames, the better. Wrap-around glasses block light coming from the side, but may cause distortion.
To check lens quality, hold the glasses at arm’s length and look at a straight line in the distance. When you move the glasses across that line, the line should not bend.
If you wear prescription glasses, you can buy prescription sunglasses or glasses with photochromic lenses. You can also get sunglass “clip-ons” for your regular frames—or “click-ons” that attach magnetically. At a minimum, your regular glasses should have added UV protection.
