1. Advantages and problems of presbyopia-correcting IOLs

It is amazing that presbyopia correction can be achieved through cataract surgery, which is a good example of “killing two birds with one stone”.

2. Factors in choosing sunglasses

As the name indicates, sunglasses are usually used to protect you from sunlight. If your eyes are over-exposed to ultraviolet (UV) rays from the sun, you would have serious eye problems that may not become apparent until you are much older. Generally, the young are more susceptible to sun exposure than the old because they spend more time outdoors.

3. Tips for selecting designer sunglasses

Recently, more and more designers pay their attention to sunglass business. Nearly every notable designer is on his/her way to sunglass market. Even some of high-end designers, such as Chanel, Dior, and Prada, are launching sunglass lines. Sunglasses and fashion are linked closely.

4. Discovering Factors Impacting Vision

New studies discover that eye disorders can be associated with statin drug use, occurring in about 0.1% of cases. Revealed by Casey Eye Institute, study results published in Ophthalmology indicate that eye disorders such as improper range-of-motion function, ptosis and double vision can be caused by muscle problems, which in turn result from statin drugs. In fact, these statin drugs are originally used to help lower cholesterol and prevent strokes and heart disease.

5. Studies related to cataracts

Researchers from the National Eye Institute (NEI) and NASA have developed an “early warning” testing system, which can alert eye doctors to first signs of cataracts.

6. Study Results of Glaucoma

Professor Isaac Schweitzer from University of Melbourne described a severe case of depression directly associated with the use of glaucoma eye drops. He pointed out in the October issue of the Medical Journal of Australia that glaucoma eye drops such as beta-blockers should be avoided by older people in controlling high eye pressure.

7. New types of eyeglass lenses

Blue-blocking lenses are traditionally used to block those harmful blue rays. However, blue-blocking lenses have been proved by scientists from John Carroll University in Cleveland to provide additional benefits. These new lenses are claimed to benefit people who have difficulty falling asleep at night. Blue light rays are supposed to delay the production of melatonin, which helps induce sleep as part of natural biological clock. In this case, by blocking blue rays during several hours before bedtime, these blue-blocking lenses can actually improve sleep patterns. In addition, those researchers say that blue-blocking lenses can also reduce symptoms of attention-deficit hyperactivity disorder.

9. Publicly concerned visual problems

Blurry vision is quite common in the United States currently. A major survey conducted by researchers from National Eye Institute says that about half of all US adults are suffering blurry vision. In fact, blurry vision is the most common symptom of refractive errors of the eyes, including nearsightedness, farsightedness and astigmatism. These errors can affect young adults, middle-aged individuals and older adults of all ethnicities. Researchers of the survey estimate that eye care addressing refractive errors costs the US government between $3.8 billion and $7.2 billion every year.

10. Vision problems about infants and children

Statistics show that premature infants are more susceptible to organ damages including the eyes. The sight-threatening eye disease retinopathy of prematurity (ROP) occurs in one third of premature infants. Good news is that there is now a new method in detecting this disease. Researchers in Sweden have developed a model named WINROP, which is used to measure infants’ weight and analyze their IGF-1 levels in blood. IGF-1 is linked to both ROP and infant weight gain. The model has been reported to determine an infant’s risk of ROP by tracing its weight gain process. This determination can be achieved at a time earlier than an assessment from an ophthalmologist and certain eye exams can also be eliminated.
