Many means have been used over time to correct vision. The monocle and eyeglass on a stick came before prescription eyeglasses that had first had limited styles. As technology improved, lenses for glasses were getting smaller.

A lot of people were looking for eyeglasses to wear that they didn’t have to worry about being lost or getting broken. Contact lenses were great but expensive when they came along. You would have to get new lenses if you lost them or dropped them.

Someone I knew lost a contact lens and developed an eye infection. The doctor found on examination that the lens had slipped out of place. Rigid contact lenses took some getting used to. People wanted softer lenses that were flexible, and easy to put in.

People wanted lenses they could wear all the time because the softer lenses had to be removed and cleaned every night. As more people were able to afford contacts because of the lower prices they got sick and tired of cleaning them and the expense of all the cleaning solutions needed.

It would be wonderful if contact lenses could be disposed of at night and people could get rid of the cleaning solutions. Disposable lenses came out in 1987 and were designed to be worn for a certain period of time before you needed to dispose of them.

There are terms and explanations that will help you understand disposable contact lenses. Contact lenses that can be worn for up to two weeks, discarded and replaced are called disposable lenses. Frequent Replacement lenses are replaced anytime from one to three months.

Every six months traditional/reusable lenses are replaced if not before. You can wear Extended Wear lenses for up to two weeks even while you sleep. The need for cleaning solutions is eliminated with daily disposables because they are removed and discarded every night.

Together with your doctor the right replacement schedule for you will be decided on. How you wear your contacts will help determine how often your will need to remove, replace, and/or discard them. Day and night Contact Lenses - You wear these lenses day and night for up to 30 days.

After they are removed you get rid of them. The best idea in my opinion is the use of Day and Night Contact Lenses if you can tolerate them. Think about what you can do with the extra time you will have since you won’t be cleaning your lenses every night.

You eyes will be healthier the more often you replace your lenses. Your eyes could be come very uncomfortable and you could become prone to eye infections because over time lipids, proteins, and calcium could build up on them.

Some reasons to wear disposable lenses are for theatrical purposes and color changer lenses are often used. Among the wide variety of contact lenses available are animal eye lenses and those with company logos. What are the benefits, if there are any of disposable contact lenses?

Lenses are sterile and there is a lower risk of infections. There is little time for calcium, proteins, and lipids to build up on them. You will have clearer vision with them. They are not to be used with any cleaning solutions.

Storing cleaning solutions and having them is no longer necessary. The ideal lens for people with allergies is the daily disposable lenses especially during allergy seasons. If you only wear contacts a few times a week, these are great. If you wear contacts only a few times during the week, these are cheaper.

If your lose them or you rip your lenses simply throw them out and open a new package. There are greater benefits to disposable contacts than there are to eyeglasses.

It used to be common for workers to scoff at the idea of wearing any sort of
personal protection equipment, or PPE. However, the times, the technology and
the laws have changed. The workplace today is a much safer place as a result.

The Occupational Safety and Health Act was passed in 1970 to “assure safe and
healthy working conditions for working men and women”. OSHA, the governmental
agency responsible for the enforcement of the 1970 Act, determines the safety
regulations required for all businesses in the US.

Hardhats, safety glasses and
goggles, steel-toed boots, protective clothing, harnesses and radioactive
dosimeter badges are just a few examples of PPE that may be required on today’s
job-sites. The degree and type of PPE use is dependent on the industry.

Mandatory Personal Protective Equipment

OSHA requires that all workers use mandatory PPE in any job that poses a threat
to one’s health. It is the employer’s responsibility to assess the workplace for
potential health threats and implement the necessary steps to address any
hazard. If such a hazard is present, the employer must supply the PPE and
educate the employee on both the potential hazards and the proper use of the
PPE.

Safety glasses must be worn in any situation where the worker is or might be
exposed to flying debris, often in the form of sparks, dust or splashes. The
safety glasses of today have advanced far beyond the thick, black rimmed
spectacles or the awkward goggles of the 1950s.

Safety glasses can be made to
a prescription and safety bifocals, trifocals and progressive focus lenses are
standard. The lens material, too, has changed. There now exist several
options, from the original plastic to a new substance, polycarbonate.

Polycarbonate lenses are lighter and more impact resistant, but sacrifice
optical clarity. A third material is Trivex, the most impact resistant, while
retaining excellent optical clarity, but this lens material is quite expensive
and still not as widely available as polycarbonate. All of these materials can
be coated a variety of tints, both cosmetic and functional.

Goggles have become
somewhat of a dinosaur, as the tendency to fog, the poor optical clarity and the
downright discomfort have made them obsolete, except in specific circumstances.

Z-87 Cerification

Any safety glasses that meet or exceed OSHA standards has “Z-87″ stamped on the
lens or temple piece. Thanks to advances in chemistry and the safety industry,
the safety glasses of today, while virtually indistinguishable from trendy,
brand name sunglasses, protect the user from almost any hazard from a flying
chip to a caustic liquid.

LASIK is the one of the most prevalent corrective eye surgery procedures, chosen by many to alleviate their vision troubles.

LASIK vision correction is a simple procedure where the corneal tissue is carved to accomplish desired refraction and improved vision acuity. LASIK vision correction is a mere 20-30 minute chore. A single surgery is normally enough to restore clear vision. Though rare, some patients might have to go through surgical enhancements.

In general, LASIK provides clear vision almost instantly. Many patients experience a significant improvement right after the surgery. However, a few patients may have blurry vision for a day or two, which certainly wears off as soon as the cornea is completely healed. Patients might have to take a few precautions as prescribed by the eye surgeon. This certainly aids in a speedy recovery.

It is recommended that you carry out a basic research when choosing an eye surgeon to perform LASIK vision correction for you. Any type of vision defect should not be ignored. It is essential that you do the needful to correct your vision anomaly. Do bear in mind that LASIK is a superlative option for the same. It is just a matter of making an informed decision and carrying it out.

LASIK vision correction once used to be a procedure that could be accessed by a select few people. However, owing to a lot many finance options, LASIK is now accessible to almost everyone. Therefore, it’s time to throw away those eyeglasses and enjoy life to the fullest through LASIK vision correction.

At one time, promotions on television advertised a new,
sexier you if you elected to lose the glasses and pop in a
pair of contact lenses. This image has always been
demonstrated in Superman comics, television programs and
movies.

He’s a bit of a geek or too normal a guy, but when the
glasses come off - he’s Superman. Fortunately, the image-
makers and shakers that relegated eyeglasses to the
awkward, the nerd gear of decades past has begun to embrace
glasses for the fashionable, functional necessity they have
become.

The differences between glasses and contact lenses are more
related to personal issues of comfort than to image.
Arguments can be made in support of contacts over
eyeglasses.

For example, contact lenses are worn directly over the eye
allowing natural vision and no distortion as some eyeglass
wearers may experience because of the small gap between the
lens of the glasses and your eye.

There is always a constant awareness of the frames as well
as the reflections off the backside of the lens. While most
eyeglass wearers become so accustomed as to hardly notice
the discrepancy, it becomes more pronounced when switching
between contacts and glasses.

Glasses can fog up when the temperature changes and they
might be a distraction during physical activities,
especially sports where you don’t want your glasses to be
broken. Contacts suffer neither of these. Eyeglasses can
be made with tinting lenses that allow them to turn into
functional sunglasses, but contact lens wearers can pick
any pair of sunglasses they want.

For the particularly fashion conscious, contact lenses
coordinate with everything in your wardrobe. But for all
their differences, both require cleaning and gentle care.
Both correct astigmatism (irregular cornea shape) and with
modern technology, both are very affordable. A new pair of
eyeglasses and a new pair of contacts is comparable in
price for the same prescription.

The decision between contacts or eyeglasses is no longer
one associated with social stigma or social image, but
rather of the image and look you want to project to the
world. It’s all truly dependent in this day of modern
fashion on what makes you feel comfortable and look great.
