People who have trouble seeing around the “edges” may have peripheral vision problems, discussed in this new All About Vision feature.

Recently added to the eye conditions section, the new article mentions different causes of peripheral vision problems such as glaucoma, detached retinas and eye occlusions.

All About Vision’s newly updated contact lens FAQ offers numerous tips about wearing schedules, contact lens solutions and basic care.

Check out several recent items in the contact lens news section, including an announcement regarding availability of the new Acuvue Oasys for Presbyopia contact lens.

All About Vision has appointed nationally recognized cataract and refractive surgeon Robert L. Epstein, MD, to its Editorial Advisory Board.

As one of the first surgeons in the United States to perform LASIK, Dr. Epstein brings a wealth of expertise to the task of ensuring that All About Vision educates consumers with accurate, comprehensive information.

Dr. Epstein is medical director and chief surgeon at Mercy Center for Corrective Eye Surgery in Chicago and has regularly performed LASIK, PRK, epi-LASIK, Crystalens implantation and other procedures.  He helped develop multifocal LASIK and has been awarded several patents, including one for a device that increases the safety and accuracy of laser vision correction.

Two new articles have expanded All About Vision’s cataract section with comprehensive explanations of presbyopia-correcting intraocular lenses (IOLs) for cataract surgery.

Presbyopia causes near vision focusing problems beginning at around age 40.

If you need cataract surgery, you also may want your presbyopia corrected so that you can see at multiple distances.

Crystalens and accommodating IOLs potentially can provide focus at all distances by shifting with the movement of eye muscles. Multifocal IOLs have different zones, which provide vision at near, intermediate and far ranges.

All About Vision served more than 2.3 million unique visitors (measured weekly) in the first quarter of 2009, up about 20% from the same period in 2008.

During that period, three of the site’s top 100 articles more than doubled in page views. Blepharitis was up 105%, Cataract Surgery rose 100% and Eye Color increased 535%.

Google generated 67% of site visitors, which originated in 230 countries, although 84% of visits were from the U.S. and Canada.

A total of 10,823 websites sent traffic to All About Vision during this period, including Wikipedia, Gunnar Optiks, Facebook, iVillage and Slate.

New discoveries continue to be made about glaucoma and macular degeneration, eye diseases that can cause blindness.

All About Vision recently posted two news items that explain more about what causes these diseases.

Low cerebrospinal fluid appears to be present in both Alzheimer’s and glaucoma. Investigations into abnormal presence of serum cystatin C (a marker for kidney disease) also have shown that chronic kidney disease and macular degeneration sometimes occur together.

Two recently added All About Vision articles explain an eyelid bump known as a chalazion and what 20/20 vision means on eye charts.

A chalazion looks very similar to a stye, but may not go away unless it is cut open and drained.

While 20/20 vision is a familiar term for good vision, many people don’t understand how eye charts are used to measure eyesight during routine eye exams.
