Causes of Red Spots on Your Eyes

The Hargrave Eye Center’s latest post:

At some point, you might look into a mirror and see a red spot on one of your eyes. Although the sight appears distressing, the spot is not necessarily a serious medical problem. The spot forms when a fragile blood vessel beneath the conjunctiva ruptures and leaks blood. The condition is referred to as a subconjunctival hemorrhage.

Hemorrhage Causes

The blood vessel break or rupture commonly occurs due to increased pressure in the eye. Sometimes the spot may occur for an unknown reason. The leakage might also occur when someone’s blood pressure rises. Other contributing factors include:

  • Allergic reaction
  • Coughing or sneezing
  • Eye injury
  • Infection
  • Physical straining
  • Rubbing the eye
  • Vomiting

Additional causes include:

  • Anticoagulant medications
  • Bleeding disorder
  • High blood pressure
  • Diabetes
  • Benign or cancerous growths categorized as actinic granulomas, conjunctival epitheliomas or keratoacanthoma. Unusual growths must be evaluated by a medical professional.
  • Conjunctival hemangioma refers to a group of abnormal blood vessels that sometimes develop on the sclera. The condition is typically benign although troubling in appearance.
  • Diabetic retinopathy refers to the condition when an ocular blood vessel ruptures secondary to high blood sugar levels. The blood often then causes floaters or dark spots in the diabetic’s visual field. The vision might also be blurred. Patients might experience a decrease in night vision. Colors might seem faded. Retinopathy is commonly the symptom that leads to diabetic’s to realize a problem exists.
  • Episcleritis involves inflammation of the episclera, which is the thin layer of tissue between the conjunctiva and the sclera. The layer contains a series of delicate blood vessels. The condition often resolves itself. However, up to one-third of the cases are due to inflammation in other body regions that require medical intervention.
  • Pinguecula refers to a growth on the sclera or a thickening of the outer layer of the sclera. The area often appears raised and yellow. When irritated by the sun, wind or debris, the area becomes reddened and swollen.
  • Sickle cell anemia is a genetic blood disorder involving abnormally shaped red blood cells. The shape, size and stiffness of the cells make it difficult to travel through fragile vessels and carry hemoglobin. Patients living with the disorder may develop what appears to be comma-shaped red lines on the sclera. These are abnormally shaped blood vessels. The eye might also develop red spots secondary to hemorrhage.

The Future of Smart Glasses

The Hargrave Eye Center’s latest post:

When Google Glass was first announced, it was treated as a potential revolution, but what was announced as a bold augmented reality future never really took off. Fortunately, it’s not an uncommon occurrence. Virtual reality struggled for decades before reaching a level of sophistication and user interest to properly enter the market, and the rise of virtual assistants followed a former trajectory. Smart glasses are alive and well. Here are some of the most exciting opportunities coming down the pipeline in the next few years.

ODG R – 7 Smartglasses

While smart glasses original caught hold of the public imagination for their entertainment purposes, augmented reality shows a lot of promises for a wide variety of business models. The ODG R – 7 comes in a consumer model, but the most interesting features come in the form of the R-7HL, designed explicitly for hazardous conditions. These smart glasses could provide critical information to people working in the manufacturing and maintenance sectors and provide them with the relevant information they need to reduce accidents.


Epson has long been seen as a printer manufacturer, but they’re making some aggressive moves to corner the augmented reality market. Their Moverio device was first launched in Southeast Asia in 2012, but they’ve been steadily working on expanding its capabilities so it can see wider adoption throughout the world. The latest models offer support for video, and they’re already seeing significant use in the medical sector. The hands-free approach Moverio provides makes them an ideal choice for surgeons and clinicians who can use the device to access the data they need while still having free use of their hands and specialized tools. It also shows promise in the field of dentistry, allowing providers to see a heads up overlay of a patients’ mouth while they do their work.

Vuzix M300

The future of augmented reality is likely one where there’s no one size fits all solution. Each headset will come with its own features and capabilities specialized to certain needs that allow them to remain affordable and lightweight. That’s the case with the Vuzix M300, an AR headset built for the needs of enterprise level businesses. The high level specs like Wi-Fi connectivity and 16GB of storage can give business leaders the data they need quickly and effectively without having to rely on computers or mobile devices.

Preparing For Your Eye Exam

The Hargrave Eye Center’s latest post:

Even if your eyes are healthy, it is a good idea to have an eye exam once every few years. If you wear corrective lenses or if you have a medical diagnosis, such as diabetes, that may affect your eyesight, you should have an eye exam once a year.

An eye exam consists of a series of tests to evaluate your vision and to check for any eye diseases such as macular degeneration or glaucoma. If you want to benefit from your eye exam, there are a few steps to take before you arrive for your appointment.

Identify Issues

Think about why you want to get your eyes examined. Is it a routine checkup or have you been having problems with your eyesight such as blurred vision, double vision or poor night vision? Do you have any questions about your eyesight that you would like your optometrist or ophthalmologist to address. If so, right the issues down as you think of them.

Even if you are sure you will remember what you need to say to the eye care professional, it is easy to get sidetracked during an appointment and forget to ask about things you want to know. Writing them down will help ensure that all your concerns are addressed.

Bring the Appropriate Paperwork

There is some paperwork you should bring to your eye exam. First, bring alone any insurance cards. If you don’t have vision insurance, or if you have a deductible or co-payment, arrive prepared to pay. Most professionals accept cash, checks, debit and credit cards.

Second, your eye care professional may ask you to fill out some forms dealing with your vision and health issues. Your provider will probably want to know the name of your primary care physician. He or she will also want a complete list of any prescription and non-prescription medications you are taking. It’s easier to complete these forms at home and bring them with you to your appointment.

Plan for Safety

Your optometrist or ophthalmologist may want to dilate your eyes during the exam. Dilating your eyes can help your provider check for the presence of diseases. Dilation temporarily inhibits the ability of your pupils to contract in bright light. If dilation is going to be part of your exam, plan to bring along a pair of sunglasses to protect your eyes.

Most providers will strongly urge you to avoid driving after your eyes are dilated. You may want to arrange for ride share or for a friend or family member to take you home after the appointment is over.

Getting regular eye exams is an important part of your healthcare. Before you go to an eye appointment, make sure you make note of anything you want to discuss with your provider. You should also bring along any documentation your provider has requested. Finally, if your eyes are going to be dilated, arrange for transportation to get home.
