Frequently Asked Questions

Can an eye exam detect high blood pressure?

Yes, an eye exam can detect signs of high blood pressure, also known as hypertension. During a comprehensive eye examination, an optometrist or ophthalmologist often conducts a procedure called ophthalmoscopy, or funduscopy, which involves examining the retina at the back of the eye. The retina is supplied with blood vessels, and changes in these vessels can be indicative of systemic health issues, including high blood pressure.

When blood pressure is consistently high, it can cause changes in the retinal blood vessels, such as narrowing or kinking. This condition, known as hypertensive retinopathy, can be seen through the ophthalmoscope. The healthcare professional might observe narrowed blood vessels, bleeding in the back of the eye, or spots on the retina.

If an eye doctor detects signs of high blood pressure during an eye exam, they will typically recommend that the patient consult their primary care physician for further evaluation and management of blood pressure.

This is one of the reasons why regular eye exams are so important; not only can they detect eye diseases, but they can also provide insights into one’s overall systemic health.

There are several eye diseases that are commonly encountered. Here are five of the most common ones:

  1. Cataracts: A cataract is the clouding of the lens inside the eye, which leads to a decrease in vision. It is a very common eye disease, especially among the elderly. Cataracts can cause blurry vision, difficulty with bright lights, and faded colours.
  2. Glaucoma: Glaucoma involves damage to the optic nerve, usually due to increased pressure in the eye. It can lead to vision loss and blindness if not treated. Often, there are no early symptoms and vision loss is gradual, making regular eye exams crucial for early detection.
  3. Age-Related Macular Degeneration (AMD): This disease affects the macula, the part of the retina responsible for sharp, central vision. AMD is a leading cause of vision loss among people aged 50 and older. It can cause blurred or reduced central vision, affecting activities like reading and driving.
  4. Diabetic Retinopathy: This is a complication of diabetes and occurs when high blood sugar levels cause damage to blood vessels in the retina. This can lead to blurry vision, floaters, and eventually blindness if not managed properly.
  5. Dry Eye Syndrome: This is a common condition that occurs when the eyes do not produce enough tears or the tears evaporate too quickly. This leads to the eyes becoming dry, itchy, and uncomfortable. In severe cases, it can cause visual disturbances and damage to the surface of the eye.

Regular eye examinations are important for the early detection and management of these common eye diseases, especially since some of them might not have noticeable symptoms in the early stages.

Yes, there are cosmetic contact lenses available for people who wish to change or enhance the appearance of their eyes. These lenses come in various colours and designs, allowing you to alter your eye colour or create special effects. Cosmetic contact lenses are available both with and without vision correction. However, it’s crucial to obtain these lenses from a reputable source and with a prescription from an eye care professional. Wearing non-prescription cosmetic lenses without proper guidance can lead to eye discomfort, infections, or even depriving the cornea of necessary oxygen to function which can lead to serious health and vision issues.

Allergies can cause eye irritation and discomfort, making wearing contact lenses challenging for some individuals. However, certain types of contact lenses, such as daily disposables or lenses made from specific materials, might be more suitable for allergy sufferers. Consult your optometrist to discuss your allergy symptoms and determine the most appropriate contact lens options or if prescription allergy eye drops are recommended. Proper lens care, including regular cleaning and avoiding allergens that exacerbate symptoms, is essential to manage allergies while wearing contact lenses.

Contact lenses can exacerbate symptoms in individuals with dry eyes. However, some contact lens options are designed to alleviate discomfort for those with dry eyes. Specialized lenses, such as those with high moisture content or designed for extended wear, might be suitable. Your optometrist can recommend specific contact lens types or prescribe lubricating eye drops to help manage dry eye symptoms while wearing lenses. It’s essential to discuss your dry eye condition with your eye care professional before starting or continuing contact lens wear to ensure the best possible comfort and eye health.

If a contact lens feels stuck in your eye, try not to panic. Firstly, wash your hands thoroughly and use lubricating eye drops approved for contact lens wear to moisten your eye. Gently massage your upper eyelid while looking in the direction of the affected eye to help dislodge the lens. If the lens remains stuck, avoid excessive rubbing, as this can cause irritation. Try blinking or using rewetting drops to see if the lens moves. If unsuccessful, seek immediate assistance from an eye care professional to safely and effectively remove the contact lens.

While contact lenses are safe when used properly, there are risks associated with their wear. These risks include eye infections, corneal ulcers, allergic reactions, dry eyes, and discomfort. Improper hygiene, extended wear, sleeping with lenses on, and swimming or showering with lenses can increase the likelihood of these complications. It’s crucial to follow your optometrist’s guidelines, practice good hygiene, and adhere to wearing schedules to minimize the risks associated with contact lens wear. Immediate consultation with an eye care professional is necessary if you experience any discomfort, redness, or vision changes while wearing contact lenses.

It’s highly advisable to avoid wearing contact lenses while swimming or showering. Water, including tap water, pools, hot tubs, lakes, and oceans, contains microorganisms that can adhere to your lenses and cause eye infections. These microorganisms can lead to severe eye conditions, such as bacterial or fungal keratitis, which can be painful and sight-threatening. Always remove your contact lenses before any water activities to prevent potential eye infections and complications.
