Vision

Surgery may correct distance vision, but it creates the need for reading glasses. Reading glasses look like normal glasses, but they actually give you good distance vision and good reading vision. For detail activities such as prolonged reading, have a pair of reading glasses made that provide balanced near vision. Almost a third of the American population needs reading glasses, but engineers designing web sites are typically under 40 with perfect vision. This often leaves them with perfect reading vision, without glasses, in old age, despite having lost accommodation through presbyopia. People who do not need glasses for distance vision may only need half glasses or reading glasses. In the past, traditional eye exams for near vision have resulted in glasses suited only for reading printed material, not for viewing computer screens. People with natural 20/20 distance vision will likely need reading glasses when presbyopia develops. Even if you achieve excellent vision through surgery, reading glasses are usually necessary beyond 45 years of age. If you have Lasik to correct your distance vision, you’ll still need reading glasses around age 45. Of course, one can use two different pairs of glasses, each with single vision lenses – one pair just for reading, and another for looking into the distance.

Distance

This is what reading glasses are about; they let you focus in on fine detail at a close distance. Baby boomers who have LASIK may end up trading in their old distance glasses for reading glasses. For those who need distance of midfield glasses, bifocals can often be the answer to providing for both distance and reading needs. Other customers may wish to consider the option of owning two pairs of glasses; one pair for distance and another for reading. And with half-eye reading glasses, you can look down through the lenses for reading and over the lenses to see in the distance. They will turn your standard distance glasses into reading glasses or your reading glasses into super magnifying lenses.

Wearing Your Glasses

Contacts have given me back some youth, but when I have them in I have to wear reading glasses. Speaking of glasses, I wear reading glasses when using a computer. I would recommend this group to anyone looking for unique and/or quality reading glasses – Roseanne-Arizona. And despite Dorothy Parker’s famous quip, women do look attractive who wear eyeglasses for reading. This means to wear the compact reading glasses down a bit on your nose. If you already wear regular glasses or reading glasses, you may be tempted to dismiss the need for computer glasses. Even non eyeglasses wearers can wear them over their sunglasses when working or reading outside. You wouldn’t wear reading glasses for driving, or at least I hope you wouldn’t. I think it was because I kept reading books with dimmed lights that made me started to wear glasses. There is no need to wear reading glasses underneath your safety glasses ever again.

Computer

These glasses give these people the ability to have proper eye protection, and allow easy reading of plans, instructions and computer screens. Some may need to use reading glasses for close work such as reading, using a computer, or sewing. For activities like reading or working on a computer, patients who’ve had cataracts removed commonly require reading glasses. Caution should be used concerning buying ready-made magnifying or reading glasses off the rack in stores to use as computer glasses.

Case

By using a reading glasses case you will prevent accidents that could ruin them. Mini reading glasses almost always come with a case designed specifically for this type of reading glasses. Plastic or metal reading glasses can be used with either a hard or soft case. Most likely a soft case will come with plastic reading glasses. The soft fabric protects the lens while the soft case is basically just storage for the reading glasses. Often such readers come with a hard case that is designed to store a specific style of reading glasses.

Lens

That is when you start reaching for reading glasses, because you need the extra power that your own lens can’t provide anymore. Off-the-rack reading glasses have the same lens power in each lens. Flip-up reading glasses – these are like the flip-up sunglasses, except they provide a magnifying lens. Even contact lens users often use reading glasses.

Prescription

If you’re experiencing those problems, visit your eye doctor for a reading glasses prescription. While pinholes are not as cheap as off-the-rack reading glasses, they are considerabley cheaper than individual prescription glasses. Purchasing reading glasses made up to your prescription is the perfect way to solve this problem. If they say you need a prescription, tell them that reading glasses can be bought in drugstores without a prescription. Over-the-counter reading glasses are inexpensive eyeglasses that can be purchased in variety, drug, and discount stores without a prescription.


As many as six out of every ten people need corrective lenses, and as many as three million people in the UK currently use contact lenses as opposed to spectacles in order to improve their vision. Contact lenses provide a more natural form of vision correction, and many people actually see better with their contact lenses than they do with spectacles. Furthermore, contact lenses are not only more aesthetically pleasing but they also offer many practical advantages for sports and recreational use.

“Perfect vision” occurs when light rays converge at a point directly on the retina and contact lenses are used to refocus light rays for those whose vision requires aid. Most common vision impairments, such as Myopia (short-sightedness), Hyperopia (long-sightedness) and Astigmatism can be treated with contact lenses, while recent technological advances have produced many more options for treating each kind of problem.

Earlier contact lenses were made from a material that restricted the flow of oxygen to the cornea and often made blinking uncomfortable due to their small size, while lenses were prone to fall out. Furthermore, lack of oxygen to the cornea was often an instigating factor when a person contracted an eye infection. Nowadays, however, contact lenses are made from materials which allow oxygen to pass more freely to the eye, allowing the eye to ‘breathe’ comfortably. This allows today’s lenses to be bigger in diameter, affording greater comfort and peripheral vision while reducing the image distortion which can be caused by some spectacles.

Contact lenses offer several advantages over spectacles. For one, contact lenses help provide unobstructed peripheral vision as they are worn next to the eye and so don’t distort objects the way spectacles can sometimes do. Secondly, since contact lenses move with your eye, you’ll always be looking through the optical centre of the lens, where vision is best. Other advantages of contact lenses include the fact that they won’t become fogged up, smudged or rain spattered, plus they won’t slide down your nose. You’re also highly unlikely to sit on contact lenses and break them!

Most contact lenses are worn on a ‘daily wear’ basis, being removed from the eye in the evening and put back in the next morning. However, everyone has a different lifestyle and, to reflect this, there are a number of different wearing schedules. Daily disposable lenses are designed for daily wear and are worn once before being thrown away, while extended wear lenses are specially designed to be worn continuously for up to a week or a month at a time before being discarded, although they should be removed nightly and cleaned with an optometrist-recommended solution.

Contact lenses should only be fitted by or under the supervision of a registered optometrist, qualified dispensing optician or medical practitioner, and it is important to have regular check-ups to make sure your eyes remain healthy and to reassure yourself that you are using the best lenses for your particular needs. The latest technological advances have seen almost constant improvement in the quality of contact lenses, meaning that almost anyone who requires vision correction and wants to wear contact lenses opposed to spectacles can do so.


Contact lenses have made lives simpler for millions of people world wide, today no matter what part of the globe you are from if you have ever worn a pair of glasses in your life chances are you have considered getting contact lenses. Contact lenses are worn by over 125 million people the world over. Apart from helping people get rid of glasses, contact lenses also offer many more features that conventional visual aids like glasses cannot offer.

As mentioned earlier the biggest advantage of contact lenses is that they are almost invisible, and unless a person tells you he or she is wearing contact lenses it is almost impossible to find out. A majority of the people in the world today wear contact lenses for this cosmetic purpose alone. It is not uncommon for people to completely ditch their glasses in exchange for contact lenses. Apart from making people with glasses look prettier, contact lenses also have more scientific advantages spectacles to do not have.

Compared to a pair of glasses, contact lenses allow for a much wider field of vision. Since glasses are limited in that they have very little or no visibility at the extreme ends they are disadvantageous to people like sportsmen and soldiers. In fact most infantry soldiers with glasses prefer contact lenses as they provide better field of vision, and modern day contact lenses can be worn for long durations of time without any problems. Also contact lenses are not bulky or prone to breakage like spectacles. People that are involved in manual labour or sports activities like football, baseball etc cannot dream of wearing spectacles to work. This is where contact lenses have a unique advantage.

Another advantage that contact lenses have when compared to spectacles is that contact lenses do not steam or fog like spectacles, also contact lenses are unaffected by rain and other weather conditions that directly affect glasses. A popular area where contact lenses are being used today is altering the colour of the iris, by wearing cosmetic lenses a person can alter the colour of his or her eyes within minutes. Most cosmetic contact lenses are certified by the FDA and can be used without any additional complications, however all contact lens users are advised to maintain proper hygiene while using contact lenses.

If you are currently wearing spectacles and considering switching over to contact lenses then there are a few things that you need to keep in mind. Contact lenses require a little more care when compared to glasses. Also contact lenses cannot be worn for longer duration of time in the beginning. It takes time for the eye to adjust to the contact lenses, so if you are expecting to get used to your new contact lenses immediately think again. Also if you are part of a profession where glasses are actually impairing your day to day activities then it is always a good idea to get yourself a pair of contact lenses. Remember always get professional help and use only prescribed contact lenses.
