Some of the leading causes of blindness—such as glaucoma or diabetic retinopathy—can begin without any symptoms. That’s why Eye Associates of South Texas and the American Academy of Ophthalmology urge all healthy adults to get an eye exam at age 40, even if their vision seems fine. Early signs of disease and changes in vision may start to happen at this age.


Prevent Blindness has designated April as Women’s Eye Health and Safety Month. This important initiative aims to increase awareness about eye diseases and conditions that disproportionately affect women.  Why are women at higher risk?  For some women, fluctuations in hormones due to pregnancy, perimenopause or menopause can bring on such changes.


Eye injuries at work are alarmingly common. These injuries range from simple eye strain to severe trauma that can cause permanent eye damage or vision loss.  The most important thing you can do to protect your vision at work is to always wear appropriate protective eyewear. This can prevent more than 90% of serious eye injuries.
