Eye flashes or photopsia can be caused by many conditions. Although flashes are harmless, they might indicate some serious eye issue which needs to be addressed immediately. Medical attention should be taken when flashes cause loss of vision and also small spots seem to float from one side to the other, thereby hindering the vision.
Migraines and very severe recurrent form of headaches which last for few hours to many days can cause visual symptoms. The light flashes look like zigzag lines, geometric patterns and sparkles when they occur with a migraine. Flashes might affect one eye or both and occur in the peripheral area of the vision. Light flashes sometime also occur due to ophthalmic migraine, a migraine without a headache.
Posterior Vitreous Detachment
The jelly like substance or the vitreous fluid fill the center of the eye and also gives it shape, is attached to the retina. With age and over time there is shrinking of the vitreous and it begins to detach from the retina. This is known as posterior vitreous detachment. In this the vitreous tugs or pulls on the retina, while the retina gets detached and stimulates it thus causing flashes to occur.
There is no known treatment for posterior vitreous detachment, through regular monitoring of the eye through eye checkups are helpful. Symptoms of this are similar to those of retinal detachment (condition in which there is permanent vision loss).
Retinal Detachment or Tear
Retinal tear and detachment also cause light flashes in the eye. This needs to be treated promptly. In case of permanent vision loss there is detachment of retina at the back of the eye, especially if the detachment takes place over the macula which is the main focus of the vision on retina. When the retina detaches from the eye, it loses the main source of nutrients. As there are photosensitive cells in the retina which are responsible for vision, the results of retina tear are severe.
Retinal damage occurs after trauma or as a complication from diabetes or posterior vitreous detachment. Vitreous gel tends to seep under the retina from the small crevices and holes formed by the retinal thinning. This in turn raises the sections and disconnects it from the eye. This can be corrected by laser treatment, cryopexy or an eye surgery.
A trauma like a hard blow on the head can lead the person to experience flashes of light. Also some medications can lead to toxic levels, like Digitalis can cause flashes of light. The symptoms of eye flashes also occur with macular degeneration, which is an age-related disease and in this the vision reduces gradually.
LASIK is a common eye surgery that helps in correcting vision problems. During this procedure, the cornea of the eye is cut across by a medical expert to raise the tissues and reshape them to correct vision.
- No need of glasses: You no longer require glasses as your vision turns to normal post-LASIK surgery.
- Goodbye contact lenses: LASIK surgery will help eliminate the need for contacts. You will be able to avoid all the problems pertaining to wearing a contact lens, including lens solution.
- Quick results and recovery: This surgery enables you to return to your normal schedule immediately the day after the surgery. You can have clear and improved vision within a day.
- Improved vision: A study reveals that 95% of the people who underwent this surgery achieved uncorrected visual acuity of 20/40 and 85% of the people achieved 20/20 vision. This procedure ensures that a patient achieves enhanced vision.
- Long- lasting outcomes: A minimum timeframe of 3 months is required for the eyes to adjust, after which LASIK results are permanently noticeable in a patient. No follow up procedures are required unless something wrong went with the surgery. The patient will continue to have improved vision unless there is any normal loss due to illness or aging.

Cataract can be defined as the clouding of the natural lenses in the eyes. This is caused by the clumping of protein in the eye lens. Cataract is a common eye disorder and the leading cause of loss of vision in people who are past their fortieth birthday. Cataract can occur in one or both eyes. When diagnosed properly, cataract can be treated with surgery to prevent blindness.
Depending on where and how they develop, there are many types of cataract. The most common amongst these are:
- Subcapsular cataract: These occur at the back of the eye lens. Diabetic patients are very susceptible to this kind of cataract.
- Nuclear cataract: Yellowish-brown cataract that form in the center of the lens are called nuclear cataract. This is usually seen in cataract caused by ageing.
- Cortical cataract: Cataract in the lens cortex are known as cortical cataract. These are wedge shaped and whitish in color. Spokes protruding out of these opaque wedges can be seen moving towards the center of the eye.
- Congenital cataract: Though they are not common, babies can also have cataract. Cataract formed at birth or within the first year of a baby's birth are known as congenital cataract.
- Secondary cataract: Cataract is one of the known side effects of diabetes and glaucoma. Some steroids and medicines are also linked to cataract.
- Traumatic cataract: If your vision becomes cloudy years after an eye injury, it could be a traumatic cataract. It can take several years for this to happen.
- Radiation cataract: Exposure to radiation can also lead to cataract. This is seen sometimes in patients who have undergone radiation therapy to fight diseases like cancer.
Though the type of cataract might differ from person to person, the symptoms are usually the same. Some of the common symptoms of cataract are:
- Blurred vision
- Reduced night vision
- Increased sensitivity to light and glare
- Seeing halos around lights
- Colors appearing faded
- Double vision
A reading test is the first step towards diagnosing cataracts. This is followed by tests to measure the eye pressure. Your doctor will also need to dilate the pupil to check the condition of the optic nerves and retina.
Surgery is the safest way to remove a cataract. Surgery is usually recommended when cataract begin inhibiting your daily life such as preventing you from driving, interfering with reading etc.
In most cases, this can be done as an outpatient procedure. The earlier it is diagnosed, the easier it is to treat. Hence, if you notice any of the symptoms mentioned above, get your eyes checked at once. The surgery is a day-care surgery only, so a person can go home the same day.

Contact lenses are one of the most convenient ways to correct vision related problems. It is easily disposable and requires the least maintenance. It might have minor side effects in the form of irritations and allergies but it requires the least time for adaptability. They help to correct nearsightedness and farsightedness along with astigmatism and age-related vision problems like presbyopia. Following are the benefits and harms of wearing contact lenses.
Positive effects of contact lenses
1. Better vision - Wearing contact lenses improves your vision to a great amount, especially peripheral vision. They are comfortable to wear and can correct both nearsightedness and farsightedness. They can cause discomfort initially but are more effective than glasses. Lenses are also available in bifocals and tints and can be worn for long periods of time.

Lenses, on the other hand, are great for an active lifestyle as they require short adaptation period. They are easy to put and take care of and do not require a lot of maintenance on your part as it needs least cleaning.
Risks of wearing contact lenses
1. Dry eyes - Dry eyes are the most common side effects of wearing contact lenses
2. Infections - Contact lenses wearers are prone to infection of the cornea called keratitis. It can cause swelling, blurry vision and other problems due to lack of oxygen supply to the cornea. Infection can be prevented by maintaining the hygiene while wearing and taking off lenses.
3. Allergic reactions - Allergic reaction to the contact lens solution can affect your vision as it causes inflammation of the eyeballs and redness. It can also cause eyelid inflammation and limit your scope of vision.
