Most colored contact lenses available in the market today are tinted contact lenses. Tinted contact lenses are pigmented with certain dyes embedded into the naturally clear lens material. The color of the die is responsible for the tint or the hue or tint of the eye. Depending on the strength of pigmentation, the moisturizing colored contact lens can either mask or completely change the tint of the eye.
There are four major kinds of tinted contact lenses available, namely visibility tinted contact lenses, enhancement tinted contact lenses, light filtering tinted contact lenses and color tints.
Visibility tinted contact lens is a lens that has been treated to have a very light blue or green tint for the sole purpose of helping you see it better during application and of course in case you drop it. They are also quite easy to spot in a solution case. Due to the lightness of the tint, these lenses do not change the appearance e of one’s eye, and when worn, you see no coloration through them either.
Enhancement tinted contact lenses are treated with single bodied pigments so as to give the lens a solid translucent color. These are meant to change the color of your eyes, but only to a certain extent and only for certain types of eyes. These are recommended for people with naturally light colored eyes. The extent of the change in color depending on the contract between the wearer’s natural eye color and the color of the lens. The more the contrast, the more vibrant is the result.
Only recently made available to the general public are light filtering tinted contact lenses, designed to help the wearer excel at sports. These tinted contacts do that by filtering out certain wavelengths of light and as a result up to the visibility of other colors, which enable the wearer to see shaper, clearer and in some cases farther as well as protect their eyes from harmful Ultra Violet (UV+) rays. They’re being branded as “Super Lenses for Superstar Athletes”. The amber tinted contact lenses block out the blue wavelength of light and heighten the red, making it easier to see the ball in fast-moving sports like baseball, football, and soccer. The green-gray tinted contact lenses are better suited for slow-moving sports such as golf, which are played out in the open under bright sunshine and these help the golfer distinguish between the various greens of the course easily.
Color tinted contact lenses are solid, opaque tinted lenses used specifically to change the color of the eyes. They are made with multi-layered patterns of different colors fused together to give them the look of the normal cornea. The resemblance between the colors and patterns on these lenses and the cornea of the natural eye are in most cases, picture-perfect copies. They differ from enhancement tinted contact lenses in the fact that they are tinted with solid (opaque) colors and thus are suitable for use on dark colored eyes. These contact lenses are made available in a variety of colors, ranging from violet to green to gray to hazel. Decorative/theatrical contact lenses are classified as color tinted contact lenses, even if they are hand painted vampire contacts, goth contacts or even Chronicles of Riddick contact lenses.
What more should you know before you get yourself a beautiful pair of contact lenses?
Tinted contact lenses are usually sold as Plano or zero power contacts, meaning they can be worn by anyone and technically do not require a prescription. For those who have already prescribed contact lenses, you can let the contact lens retailer know what diopter(power) your eyes have been tested as, and they can make custom contact lenses in the same look as you want for you. However, one should expect to pay a premium for these. A sensitive topic that must be addressed is whether you should purchase contact lenses from a retailer who doesn’t require a prescription. A striking fact may lens buyers are unaware of is that as per law, a retailer can’t sell contact lenses without a prescription, even if they are Plano (zero power), since 2005. This was a result of an increase in the number of reported eye damage cases due to the sale of spurious tinted contact lenses by certain online retailers. The US FDA(Food and Drug Administration) has conducted various studies and has published a list of chemicals that are approved for use in the manufacture of tinted contact lenses. As an informed consumer, one should always check that the retailer conforms to these specifications and constraints their use of chemicals only to the approved one.
Getting a prescription along with a check-up is essential in the interest of your own eyes. If you choose to purchase your lenses from an unknown online store or from a foreign one, it is best to let your optometrist have a look at their site and make sure that you are choosing
Many horseback riders need some degree of vision correction, and others worry about eye protection while riding horses. Which is best?
Unfortunately, traditional glasses, sunglasses and contacts can get in the way of equestrian sports. Glasses tend to bounce around on the nose if they are not fitted correctly, while dirt and dust can agitate contacts. And any type of eyewear can become a hazard while riding horses.
When the goal is to protect both the eyes and the eyewear for horseback riders, the options are definitely limited.
Eyeglasses for Equestrian Sports
Glasses are a problem because they are not attached to the head, and helmets and other head protection devices can compromise the earpieces of glasses. When simply hacking around the arena or taking a leisurely trail ride in the woods, glasses should not pose much of a problem, but what about active equestrian sports?
Although there are currently no equestrian-specific eyewear options on the market for horseback riders, it is a good idea to explore safety eyeglasses as an alternative. These special glasses follow rigid ANSI rules to ensure eye safety while involved in equestrian (and other) sports and activities.
They typically have plastic and hard coated lenses that will not shatter in an accident, and often have wrap-around frames that ensure better protection around the ears and brow. Other safety features to consider when purchasing eyeglasses for horseback riders include:
- Brow guard for impact absorption
- Side guards
- Flexible nose bridge
- Scratch-resistant surface
- 99.9 percent UV protection
- Breakaway cords for clip-on attachments
It is possible to find eyewear for riding horses that are both attractive and functional, so do not worry about the aesthetic aspect at first. Instead, horseback riders should carefully evaluate the constitution of glasses for comfort and safety, which are infinitely more important.
Riding with Sunglasses
Everyone knows that the sun’s intensity can destroy an otherwise pleasant ride. Sunglasses help to cut down not only on the painful and annoying aspects of sunlight while riding horses, but also the dangerous effects of riding with unprotected eyes.
In most cases, it is possible to fit a pair of regular safety eyeglasses with alternative lenses to make them sunglasses. Horseback riders can also use clip-on shield attachments that do not replace the lenses at all, but simply provide a protective shield.
Many horseback riders have discovered that polarized sunglasses are ideal for equestrian sports. These specialty glasses are manufactured to reduce not only the direct light from the sun, but also the glare from glossy surfaces, such as water, metal and plastic.
Horseback riders should make sure that all types of eyewear, including sunglasses, are sufficiently comfortable for equestrian sports. From the nose bridge to the ear pieces, the glasses should fit snugly to the face with no shifting as the wearer moves.
Additionally, it is important to remember that sunglasses attachments that fit over existing eyeglasses can constitute a safety hazard. For example, if the attachments are made of glass rather than plastic, wedges might make it under the eyeglasses in an accident, damaging the eye.
Riding with Contacts
Some horseback riders do not like eyeglasses at all, and prefer the flexibility and inconspicuous nature of contact lenses. However, contacts are difficult to wear while riding horses because if dust, dirt and other debris find their way into the eye, the contact lens can aggravate any damage or irritation.
Consequently, most horseback riders keep a pair of safety eyeglasses for the barn, or wear polarized sunglasses over their contacts as an additional preventative measure. There are also amber-tinted contact lenses that will create a similar protection to sunglasses.
Should dirt or debris find its way into the eye while wearing contacts, horseback riders should remove the lenses immediately and wash out the eyes with water. Nearby water hoses work well for this purpose, and some riders even wear safety goggles over their contacts to avoid such a situation.
Evaluating your Options
Horseback riders should talk to their optometrists when soliciting fittings for eyewear. Whether they prefer eyeglasses, sunglasses or contacts, a professionals can help riders to find safe, comfortable solutions for any equestrian activity.Continue Reading...
Where to buy the best value top quality sports prescription sunglasses for mountain biking with wrap around styling to protect eyes from dust, mud and wind.
Mountain bikers who wear glasses for vision correction have two choices when it comes to sports sunglasses; either wear contact lenses with an ordinary pair of sunglasses or invest in a pair of prescription sports sunglasses.
This article looks at the best sports prescription sunglasses you can buy for mountain biking with wrap-around styling, where the prescription is built into the lens.
Prescription Cycling Sunglasses
Sports cycling prescription sunglasses come in two main types: either an insert known as a clip-in lens which simply clips to the inside of the frame at the nose-piece, or an in-frame prescription lens, where either the entire lens has corrective power or just the central portion.
The problem with wrap around styles of sunglasses is that it is far more costly to produce a curved lens with full corrective power, which is why many branded prescription lenses from companies like Oakley or Rudy Project only offer corrective power in the center of the lens; the result is a loss of periphery vision when looking sideways. The best option is to buy sports prescription sunglasses with full corrective power over the entire surface of the lens.
Prescription Designer Sunglasses with Mirror Lenses
Many mountain bikers prefer designer style sunglasses with mirror lenses which look super cool on the bike, but if you need prescription lenses, adding a mirror finish increases production costs even more, not to mention a complicated eye prescription which may need to allow for astigmatism or a higher power level outside the standard prescription range offered by Oakley, which, for example, is between +2.0 and -3.0.
It is possible, however, to get cool wrap-around styling with a fully built-in prescription lens, both polarized and mirror finish, for a lot less than the +$400 price tag charged by many of the top brands.
Cheap Sports Sunglasses with Prescription Lenses
The way to find cheap sports sunglasses with prescription lenses is to buy direct from an optical laboratory that offers personalized service and even international delivery. Most optical laboratories have a complete range of sports sunglasses including wrap-around styles for cycling with UV anti-scratch and anti-mist lenses as standard and frames made from “virtually unbreakable polycarbonate.” Bifocal and varifocal options are also available.
To avoid any confusion over ordering the correct prescription, customers are asked to purchase online first and are then called personally to give prescription details. Alternatively, customers can ring the company direct or send an e-mail if they are not sure whether a particular lens is the right one for them.
Either way, buyers have access to a comprehensive array of styles and lenses and the assurance that their exact prescription can be built-into the best prescription sports sunglasses available in the market, at a far cheaper price than buying from an optician.

Most people rarely think about their eyes until the day comes when the newspaper has to be held farther away to be read. A decrease in vision as we age is normal, but there are many other problems that can causes vision decrease early and impair eye health. Some of those problems can be avoided with foresight and preventative measures to help maintain healthy eyes for life.
Wear Sunglasses When Outdoors
The sun’s UVA and UVB rays can damage eyes just like it damages skin. The cornea of the eye can be sunburned when eyes are not protected from directed sunlight with sunglasses. Fortunately, a sunburned cornea is usually reversible, but there is also cumulative sun damage that occurs to the eyes with sun exposure over time that is not as easy to reverse, like cataracts.
Wearing sunglasses when outdoors will prevent sun damage to the eyes and help maintain eye health. For those who wear prescription corrective lens, lenses such as transition, which automatically darken when exposed to sunlight, will protect the eyes from UVA and UVB rays. Contact lens are also available with UV protection.
Add Antioxidant Rich Foods To Diet
Antioxidant rich foods, especially those rich in lutein and omega-3 fatty acids, keep eyes healthy by protecting the eyes from age-related eye disorders like cataracts and macular degeneration. Macular degeneration is the major cause of blindness in people aged 50 and above.
Foods that are rich in omega-3 fatty acids are nuts and fatty fish like salmon. Lutein rich foods the dark green vegetables like spinach, broccoli, peas and kale.
Adding a small daily amount (a quarter of a cup) of antioxidant rich foods to a daily diet will help keep eyes healthy for life.
Take a 20/20 Eye Break
Avoid eye strain and dry eyes when working on the computer or doing other up-close work by taking an eye break every 20 minutes. Stop the up-close work every 20 minutes and look at an object 20 feet away for 20 seconds.
See An Optometrist
Barring any earlier eye problems, by age 40 it’s time to see an optometrist for a baseline eye exam, even if there has been no change in vision. After a baseline eye exam, follow up eye exams are usually recommended every couple of years. This allows the optometrist to detect an early signs of eye problems for easier treatment.
Eyes are meant to last a lifetime. Keeping eyes healthy for life does require a little foresight by eating foods rich in antioxidants and wearing sunglasses to protect eye health, taking frequent eye breaks and seeing an optometrist.Continue Reading...
Cycling specific sports sunglasses and lenses are available in a wide range of styles from leading eyewear manufacturers. While some riders may prefer to wear an ordinary pair of sunglasses to save having to buy two pairs, it’s important to understand that cycling glasses offer far more than just good looks from a top designer eyewear brand.
Why Wear Cycling Sunglasses?
Good quality sports sunglasses for road or off-road cycling protect the user from harsh sunlight but also keep out dirt, flies, dust and wind, especially important for riders who wear contact lenses. The wrap around styling that keeps undesirable light and objects out also provides a snug fit, meaning glasses won’t move around, a huge plus point if riding at speed in a competition.
Advances in technology mean that there is now a wide range of different colored lenses on the market, made specifically for varying weather and light conditions, as well as photochromatic options and a plethora of different lens coatings for both fashion and function.
Key Features of Cycling Eyewear
In addition to wrap around styling, look for the following features when buying sunglasses for cycling:
- Polycarbonate lenses – Most good brands offer polycarbonate lenses which are up to twenty times stronger than ordinary lens glass.
- Interchangeable lenses – Useful for varying light conditions and also as spare lenses should one set become scratched. Most good brands offer dark, light and clear lenses, the latter being useful for evening or night riding.
- Photochromic lenses – Allow smooth transition from low light to bright light without the need to interchange lenses; useful for competition riding.
- Comfort – Good cycling glasses fit neatly underneath a cycling helmet without pinching the side of the head; they have a comfortable non-slip nosepiece and side arms that don’t snap easily. If possible, try on glasses while wearing a helmet to ensure a good fit. Look for glasses that can be adjusted if, for example, a sweat band is required under a helmet in hot conditions.
- Weight – Sports sunglasses should be light and offer enough ventilation within the wrap around styling to prevent glasses misting up in humid conditions or when riding hard uphill. A good example is the innovative vented lenses on the Oakley Jawbone (see picture below).
- Polarized lenses – These offer riders improved clarity of the contours of a trail as, according to Al Gleek of lens maker Carl Zeiss, Inc. polarization “blocks scattered light and lets in only very focused light.”
Cycling Prescription Sunglasses
Riders who need prescription sunglasses can buy cycling specific branded glasses with either clip-in or in-frame lenses. The cost is higher for in-frame lenses although cheaper non-branded options exist from specialist optical laboratories and may be preferable to paying the high cost of a custom made prescription lens with a mirrored finish.
Sports Sunglasses Brands
The main brands offering cycling specific sports sunglasses are Bolle, Rudy Project, Oakley, Adidas, Bloc and Specialized.
All offer stylish sunglasses with a variety of features such as “thermogrip nosepads”from Bolle, affordable clip-in prescription lenses from Adidas or Bloc’s innovative “8 based curve” which offers a close fitting frame with improved peripheral vision. Expect to pay between $80 and $250 depending on features and type of lens.
Buying Sunglasses for Cycling
Whilst it is possible to wear an ordinary pair of sunglasses for bicycling, most riders prefer the key features offered by cycling specific sports sunglasses; practical wrap around styling and interchangeable or photochromic lenses that suit varying light conditions.
