I have having headache and my eyes become red when I am using my mobile for a long time or its something else.
Variety of contact lenses is used to correct refractive errors. Soft Contact (hydrogel) Lenses are most often used in various types of refractive errors but they have certain disadvantages. These lenses do not permit adequate Oxygen to pass through which is essential for health of cornea and hence they can be worn for limited hours, i.e 6 to 8 hours maximum and never while sleeping. The tear proteins get deposited on these lenses which limit their life to about a year. If worn for prolonged period or proper measures not taken to clean the lenses, cornea can get an ULCER which at times can result in permanent loss of vision. Disposable daily wear lenses provide safer alternative but the cost increases significantly. Since soft contact lenses are applied after cleaning with a solution which can be the cause of mild to severe allergic conjunctivitis which can become intolerable. Soft contact lenses are not ideal in eyes with high corneal astigmatism.
Merits of soft contact lenses are that they can be dispensed over the counter or purchased on line though it is not ideal. A correct curvature and power of a contact lens is determined by a contact lens specialist/ Ophthalmologist after measuring exact corneal curvature and using trial contact lens. Another merit is that these lenses can be accepted very easily since even on the first day they do not produce much of discomfort. These lenses can be worn off and on without any inconvenience. Recent introduction of Toric Contact Lenses have made them more acceptable in cases of moderate corneal astigmatism.
Breathing Contact Lenses:
These lenses are the one which permit significant amount of oxygen to pass through and hence can be worn for prolonged interval without any adverse effect on the cornea. These are of two types
- Semisoft or Extended Wear RGP Contact Lenses: These lenses are made up of FP 92 which is a semi rigid soft plastic and is highly permeable to oxygen. These lenses are excellent for high refractive errors, especially in patients who have high corneal astigmatism. Even cases with irregular cornea or Keratoconus, these lenses can be accepted with rewarding results. These lenses can only be fitted by an expert Ophthalmologist since precise measurement has to be carried out and various trial lenses have to be tried to evaluate the optimum fit. The lenses are made to measurement and the patient has to be precisely trained to fit the lenses and maintain them. As stated, the lenses can be safely worn while sleeping and there is practically no danger of corneal toxicity or infection. These lenses may last for 4-5 years. One of the demerits of these lenses is that they take 5-6 days to adopt and the patient is advised to use them regularly. They are excellent alternative to LASIK surgery.
- Silicon Hydrogel Contact Lenses: These are recent introduction of extended wear contact lenses with capacity to 'breathe' better than soft or hrdrogel contact lenses. Some of the recent Silicon Hydrogel Contact lenses introduced by Alcon and Bausch and Lomb can be worn for a week or so.
Silicon hydrogel lenses though indicated for prolonged wear but can cause mild keratitis and sometimes allergic keratitis if worn overnight. These lenses still needs lot of improvement to be free of complications
Advise: It is ideal to consult an Ophthalmologist specialized in contact lenses for fitting of a proper contact lenses. Advertised lenses some time misguide and can be damaging to the eye.
Sir, I mostly prefer to study online, many times I sat in front of mobile or PC for more than 40 to 50 min. Due to this I have eye pain and headache. Please suggest how to take care of eye?
I am student university level have eye irritation and eye pain I don't see light such as laptops when I use laptops I don't seen well the sun my eyes are following water what is that problem? And what I can do?
Allergic conjunctivitis is the result of a foreign particle (allergen) coming in contact with the eye. Once this happens, the immune system overreacts resulting into an inflammation of the eye. The eyes sore with pain. The over secretion of the histamine dilates the blood vessels causing the nerve to irritate and blood vessels of the eyes to expand. Some common reasons of allergic conjunctivitis include eye drops, pollen, dust mites, makeup and animal fur. The good news is that allergic conjunctivitis is easily treatable. Here are top five ways to deal with this condition:
- Taking care of the eye: It is advised not to wear contact lenses until the symptoms go away fully. If any medication is used, a person must wait for at least 24 hours before putting on the contact lenses. Sometimes our hands carry major pollens that result in allergic conjunctivitis. It is equally important not to rub the eye without washing both the hands. Many studies have also reported that frequent bathing of the eye with cold water helps to clear the symptoms quickly. Some even say that frequent splash of warm water does the trick.
- Avoid the allergen: Allergen being the villain behind the occurrence of this condition, it is very important to stay away from it. In peak pollen times, it makes sense to close the door. In case a person must go out, it makes sense to wear a sunglass. A pillow made of feathers should be changed every week to stay away from the infection. The number of dust mites at home should be decreased as much as one can.
- Antihistamines: To quickly get rid of allergic conjunctivitis, doctors often prescribe antihistamines. It can be in the form of eye drop or oral presentation. They can successfully counter the effect of histamine which the body produces because of the hyper activity of the immune system. An antihistamine can block the aggressive effect of the immune system in a short time. Some of the commonly prescribed histamines include loratadine, cetirizine, emedastine, and ketotifen. People taking this form of the medicine for the very first time should refrain from carrying heavy load or driving.
- Mast cell Stabilizers: These takes a little longer to act as compared to antihistamines. Their effects, however, are more lasting compared to its peers. Some of the popular mast cell stabilizers include nedocromil and lodoxamide. This medicine belongs to a non-steroid family and can successfully block the chemicals that cause inflammation.
- Corticosteroids: These medicines are only prescribed by doctors when the symptoms of allergic conjunctivitis are serious. They belong to the steroid family of medicine produced synthetically. They can reduce the immune response of the body quickly and reduce the swelling as well. They can have possible side-effects. It is therefore wise, to consult a doctor before using it.
My questions is what is the permanent treatment of weak eyesight or it cures naturally by foods or exercise or by any other method.

Bloodshot eyes indicate the reddening of the eye vessels. They can cause irritation and make the eye swollen. The condition may arise due to allergies, eye infections, allergies, fatigue and other illness of the eye. It does not signify a disease but indicates an eye condition which might have caused the eye to redden. Bloodshot eyes can be encountered in one or both the eyes.
Causes of Bloodshot Eyes:
One of the frequent causes of bloodshot eyes is irritants such as dry air, pollen, pet dander, dust and UV rays of the sun. Shortage of sleep also tends to make the eyes red. Inflammations of the eye can also make them red giving a bloodshot appearance. It can even happen with people who wear contact lens for more than 16 hours without soaking it in the disinfectant. At times excessive dryness can make the eyes red. Some other reasons for the eye to become red include conjunctivitis, blepharitis, glaucoma and corneal ulcer. Another concerning reason of bloodshot eyes is a subconjunctival haemorrhage. While the latter is not dangerous in nature, it can cause significant trouble if proper care is not taken on time.
Symptoms of Red Eyes:
Some of the common signs of bloodshot eyes include watery eyes, foreign sensation, burning feeling, dermatitis, falling of eye lashes, light sensitivity, swollen eyelid, itching of the eye and feeling of irritation of the eye.
The Complications Involved:
In most of the cases, bloodshot eyes do not imply serious complications. In case it happens from conjunctivitis, a person may not be able to go to work, wear cosmetics and come in public places since it is a communicable disease. If bloodshot eyes arise from a serious condition such as glaucoma and trauma, some of the possible complications may involve the following:
Vision loss due to complete blindness
Spreading of the existing condition to other persons
Eye loss in severe cases
Bloodshot eyes might arise from an array of reasons. While it cannot be totally dodged, some general preventive measures can ensure that such a condition does not arise:
Keeping hands clean by thoroughly washing them with liquid soap
Not sharing personal belongings such as washcloths, linen, and cosmetics
Get immediate medical attention in case of any eye injuries
Stay away from an environment that is full of allergens
Staying away from people who are suffering from infectious eye diseases such as conjunctivitis
Taking a shower immediately after getting in touch with an infected person suffering from conjunctivitis
Wearing eye glasses in a dusty environment. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.
I am every morning weakness in my body and cough in chest and my nose is always draining water and eye drain water in every morning please give some advice.
It is very essential in the present times to understand the training, ability and skills of the doctors whom you select for your needs.
An Eye Doctor is called an Ophthalmologist. He/she can possess following qualifications
M.S (Ophth) : This is called Master Of Surgery in Ophthalmology. It takes Three years of training in a Medical Council recognized Medical College after passing M.B;B.S and includes undertaking and submission of a thesis or research Paper during the training. It can be done by obtaining seat based on Merit, Based on reservation or Based on Donation
D.O (Ophth) : This is called Diploma in Ophthalmology. It is similar to M.S. except that training period is TWO years and does NOT include doing research paper
DNB (Ophth): This is called Diplomat of National Board in ophthalmology. The training is done after M.B;B.S in some private institutes or hospitals recognized by National board of examinations and not in MCI recognized Medical college
Long Term Fellowships: As the knowledge base is increasing, there is further training undertaken for super specializing in some specific field of eye surgery through a process called FELLOWSHIP. This includes training for about two years after M.S., D.O or D.N.B in some Institues of repute like Shankar Nethralaya Chennai, Aravind Eye Care Systems ( Madurai/ Coimbatore), L.V.Prasad Eye Institute ( Hyderabad) to name a few. The training involves doing actual work in specialized techniques under supervision and guidance of experts in respective fields like Retina, Cornea, Glaucoma, Oculoplasty, Phaco and Refractive Surgery, Paediatric Ophthalmology, Neurophthalmology etc.
Short Term Fellowships: They are similar to long term fellowships but training period is very short , like 2-3 months . The training helps a general ophthalmologist to acquire some skills in a speciality but not sufficient to be able to be a super specialist. However, some doctors with such training may claim to be superspecialists!
ACEDEMIC FELLOWSHIPS: Such fellowships test the knowledge of Doctor through two or three steps of examinations/ Viva. There is no practical training given Examples are,
FRCS: Fellow of Royal College of Surgeons
FICO: Fellow of International Council of Ophthalmologists
FAICO: Fellow of All India Collegium of Ophthalmologists
Some senior Ophthalmologists who were trained in multiple eye diseases and worked for a long time in handling them may be as good as superspecialists in some areas.
Besides Ophthalmologists, some trained personnel can undertake some eye care tasks like
Optometrists: They can assess and prescribe Spectacle power(numbers), prescribe and dispense contact lenses, run some eye tests on machines.
Opticians: They can make/ sell glasses or contact lenses as prescribed by Ophthalmologists/ optometrists. They can not prescribe. Yet, many shops do so without Optometrists.
Ophthalmic Technicians: They can operate machines like Perimetry, OCT, A scan ultrasonography, Topography etc.
Hope that now the readers are better informed about their eye care providers. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.
