Eye Care

Hi there "bloodshot eye" or subconjunctival hemorrhage can have several possible causes. You would need a review with a clinician to determine this, although if there is no underlying condition it would typically heal within 2 weeks.  Read more about them at this link:

Hi @DrHelp Im afraid I do not have enough information to assess this, would you have a picture? You may be having an infection, allergy, or other type of condition - and may need to see a general practitioner/family doctor for further evaluation if the eye tests came back negative.  

Hi @keedyg , from what you describe eye cancer sounds unlikely. In order to confirm this minimally a physical examination by your doctor would be required. Do follow-up with a provider in-person for an examination.

Hi @Sagarsingh29f the fluid on the eye surface is called the tear film, which is a complex mixture of oil, water, and mucus that coats the cornea, conjunctiva, and sclera, keeping the eye moist and lubricated. Try not to touch the eye as doing so can introduce dirt or dust, and potentially lead to infection.

Hi @Healthcomesfirst unfortunately I am unable to view your image. However, from what you describe - it sounds like you would benefit from a visit to your optician to check your refraction and vision, as incorrect/inadequate vision correction or improper fit can lead to this. If that turns out to be corrected adequately, you would need a physical examination by your general practitioner or family physician for further evaluation. 

Hi @ongjunhao1997 good questions! Have added responses to each of them separately - 

For the first question, Astigmatism is a common cause of blur vision arising from irregular shape of the cornea (superficial layer of the eye) or lens (inside the eye). It is a structural problem that is not directly affected by screen exposure (smartphone/laptop use) although excessive use of these devices without breaks can cause other eye problems that may worsen your blur vision overall. For the latter, I recommend the 20-20 rule i.e. to take brief 20 second breaks to look at something in the distance, at least 20 meters away. This can be done every hour or so when using these devices for prolonged periods, and will help reduce your risk of eye strain.

For the second question, Acuvue contact lenses are generally a good option. Most contact lenses are not suitable for use while swimming due to all the organisms in the water. There are a few specialised options, but these are costly and hard to come by. Some recommend to use daily contact lenses with waterproof goggles for protection, and to throw the contact lens away after swimming without touching the eye at all. However, this is hard to do in practice and there is still risk of contamination. One option is to consider prescription goggles that incorporate refractive correction based on your vision - this is something you can speak to your optician about for available options. Some lenses and goggles do make such claims about blue and UV light. While they may offer some protection, it is recommended to take regular precautions and especially avoid directly looking towards the sun. Hope this helps!

Hi @maybe78 unfortunately not - the Science behind blue light glasses is not definitive. Although excessive blue light exposure can affect the sleep cycle, the amount from device screens has not been conclusively shown to cause any problems to health in general or in the eye. That said, the sun itself emits large amounts of blue light/ UV radiation, and excessive sun exposure can damage the eye. Avoid looking directly, and wear sunglasses on hot days or when driving.

Ultimately if you find that you lead a lifestyle with large amounts of exposure to digital screens such as laptops, mobile devices, and televisions, here are 2 key things to improve your eye health and minimise the impact on sleep;

1) Take visual breaks
This is important, especially during prolonged continuous visual tasks such as browsing social media, reading documents, or drawing on these device screens. This means to take a break every half-hour or so, to look further away at something in the distance. You may find looking out of the window at nature every once in awhile to be particularly relaxing!

2) Avoid screen time in the 2 hours before your bed time.
Instead, try to do something relaxing such as to go for a walk, or have a conversation with your loved one (although, depending on circumstances this may not always be relaxing 😂 ). Other tips to improve sleep are to avoid drinking liquids in the 2 hours before your bed time, and to try and incorporate some exercise in the first half of your day.

I hope this helps!

Dear Jeff. It is not usual to have double vision. The cause can be due to abnormality in the brain ( Central ) or the ears ( peripheral).  It is important for you to consult an opthalmologist. Alternatively, you may visit the Emergency Department for a consultation. Imaging of the brain might be considered to rule out central causes of diplopia and tinnitus. Kindly go to Emergency department if you have any weakness or numbness of hands and legs. Thank you.

Hi @Me sorry to hear about this, hope you're feeling well after the laser! The human mind is very adaptive, and over time will gradually learn to "block out" the floaters. The process can take months, and is generally faster if you try not to pay attention to the floaters (difficult as that may be).

Nonetheless, given that you've seen your specialist and had the laser done, at least you can rest assured the underlying cause has been addressed. That said, if you suddenly notice an increase in the number of floaters, flashes of light, or blurring of vision, that would be an indication to arrange an urgent review with your eye specialist. I hope this helps!

Hi @cyeap this indicates sensitivity to light and possibly photophobia. If you experience this in association with fever or headache, you should go for a review with your doctor for an examination.

Otherwise, other possible causes include problems with your vision or inflammation in the eye. A review with an Optometrist or Ophthalmologist for an examination would be a good place to start to get to the bottom of it. Hope this helps!
