Basic knowledge of contact lenses

Contact lenses have been around for over one hundred years. In those early days, some people were not suitable to wear contact lense since the technologies were not so advanced. But nowadays, contact lenses are available for everyone. And contact lenses today are provided in more options that even colored ones are manufactured.

Contact lenses are one of the three ways that can correct eye diseases such as myopia, hyperopia and astigmatism. The other two are metal glasses and plastic eyeglasses such as LASIK. Actually, contact lense has been the choice of a considerable population. In the United States, about 20 percent of people who need vision correction wear contact lenses.

To some content, contact lenses are special eyeglasses, because they also use lenses to help people improve their vision. However, the two types do have some differences. Eyeglasses are visible to others. They have obvious frames and lenses. In contrast, contact lense is invisible to others, because the lenses are made of transparent materials. This feature of contact lenses does help some people who prefer their appearance without a pair of eyeglasses. Contact lense also eliminates their need for eye surgeries.

Contact lenses can provide the vision correction effects as well as any eyeglasses. Once you put them on, contact lenses “contact” your pupils. Contact lense is large enough to cover your whole pupil even if you turn your eyes around in all directions, so that it can provide complete vision correction. Contact lense just provides unobstructed vision, which is helpful during sports and other activities.

Low contrast sensitivity tests and treatments

Good vision such as 20/20 does not mean satisfying contrast sensitivity. Common vision tests using black letters or numbers displayed against white backgrounds can not reflect your exact contrast sensitivity, since the real world is filled with grey shades. So that special contrast sensitivity testing is necessary.

May eye diseases or conditions may cause poor contrast sensitivity, such as cataracts, glaucoma, and diabetic retinopathy, as well as the side effects from LASIK and PRK. People with low contrast sensitivity may have difficulty in some conditions, such as seeing traffic lights, spot other cars and pedestrians during night driving. Since these people have poor perception of objects that do not stand out from their backgrounds, they may even stumble when they fail to see similarly colored pavements.

The term “contrast sensitivity function” (CSF) is used to describe people’s low contrast seeing ability. A contrast sensitivity test may be included in a routine screening after the visual acuity test, which measures the ability of seeing detailed letters or numbers. With your plastic eyeglasses or contacts lenses wearing on, your eyes will be tested in together by a low-contrast test chart, which consists of bars and dots in different colored contrasts that are used to evaluate the patient’s exact CSF. Your CSF will certainly be affected by the sizes of objects: the larger the objects are, the higher CSF you can achieve.

By testing your eyes using bar and dot patterns displayed against varying contacts or intensities, your highest and lowest contrast sensitivity can be determined and plotted into a curve, which shows your contrast sensitivity readings. Tests under both bright and dark conditions can provide more detailed information about your images process capability.

As a volunteer, you can get a contrast sensitivity test as a necessary part of the evaluation of new ophthalmic devices such as LASIK excimer lasers and new intraocular lenses required by FDA. Once you are diagnosed with low contrast sensitivity, some remedies are available, depending on the source of the problem. Usually, artificial lenses with a yellow filter can improve contrast. If the low contrast sensitivity is caused by higher-order aberrations, wavefront lenses or LASIK are the right choices. Another option is intraocular lenses with yellow tints, which can also offset low contrast sensitivity.

Various types of specialty eyeglasses

Besides eyeglasses for regular wear, there are still various types of specialty eyewear or “task-specific” metal glasses. Since one pair of eyeglasses does not fit all sizes in most cases, those specialty eyeglasses such as computer glasses, driving eyeglasses and protective glasses are helpful in specific circumstances.

Computer glasses are particularly for long period or regular computer work. People wearing ordinary glasses develop computer vision syndrome symptoms such as eye strain and headache easily. Computer glasses are designed exclusively for intermediate vision during computer work, providing the best vision correction.

Some people may need special glasses for certain jobs or hobbies. For instance, ordinary bifocal glasses require wearers to look down trough the bottom part of the lenses to get close vision. For people who spend all day long on close reading, neck discomfort will surely occur. In this case, special-design bifocal and trifocal glasses named occupational bifocals and trifocals are needed. In addition, a separate pair of reading glasses is necessary for close-up work such as beading, needlepoint, crafting and so on.

Most sports require good visual acuity for satisfying performance, such as tennis ball, golfing and skiing. Sport-specific mens eyeglasses can both enhance performance and provide necessary eye protection. This type of specialty eyewear is often made of polycarbonate lenses, including skiing goggles, shooting glasses, swimming goggles and so on.

Glare reflecting off the road or the car’s windshield can be the cause of an accident because the driver failed to see the other car or a pedestrian. Driving womens eyeglasses including driving sunglasses and prescription glasses are needed to minimize the risk of accidents. Sunglasses for driving feature polarized lenses and prescription glasses for driving always have anti-reflective coating, which also aim at reducing glare.

People may also need safety eyewear to ensure their eye safety in dangerous situations. Safety eyeglasses including sports goggles and shooting glasses usually feature ultra-durability, a wraparound design, top and side shields. Some people may still like specialty eyewear just for fun and fashion.
