Floaters and Light Halos: Are They Normal? - Ophthalmology

More Info

Floaters and light halos are common visual phenomena that many people experience, and they can be concerning, especially when they change or become more pronounced. Based on your description, it seems that you have been experiencing floaters since the beginning of the year and have had your retina checked twice, both of which showed no issues. This is a positive sign, as it indicates that there are no underlying retinal problems, which can sometimes be associated with floaters.

Floaters are tiny spots, lines, or cobweb-like shapes that drift across your field of vision. They are caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become more liquid and pull away from the retina, leading to the perception of floaters. While they can be annoying, floaters are generally harmless unless accompanied by other symptoms such as flashes of light or a sudden increase in the number of floaters, which could indicate a retinal tear or detachment.

Regarding the light halos you are experiencing, especially when looking at lights at night, this can be attributed to several factors. One common cause is the scattering of light due to changes in the lens of the eye, which can occur with age or due to conditions such as cataracts. Halos can also be a result of dry eyes or corneal irregularities. If you are noticing that the halos are larger than before and that you are more sensitive to light, it might be worth discussing this with your eye care professional.

In terms of whether this is a normal phenomenon, it can be considered normal to some extent, especially if your eye examinations have ruled out serious conditions. However, an increase in sensitivity to light (photophobia) and changes in the appearance of halos could warrant further investigation. It is essential to communicate these changes to your eye doctor, as they can provide a more thorough examination and determine if any additional tests are necessary.

In summary, while floaters and halos can be normal, any significant changes in your vision or discomfort should be evaluated by an eye care professional. They can help ensure that there are no underlying issues and provide guidance on managing your symptoms. If you continue to experience discomfort or if your symptoms worsen, do not hesitate to seek further medical advice. Regular eye check-ups are crucial, especially if you notice any new symptoms or changes in your vision.
