Medical Disclaimer: Information, Not a Substitute for Care
Our eye health content, exercises and online vision checks are general information and screening aids. They do not replace a professional examination or treatment.
gozcimnastigi.com provides free information about eye health, guided eye exercises and interactive vision checks. We take great care to base our content on reliable evidence, but no website can examine your eyes. This medical disclaimer explains what our content is, what it is not, and when you should seek professional help instead.
Please read it before relying on anything you find on the site. It applies to all pages, tools, exercises and programmes, in every language.
Key points
- All content is for general information and education only.
- It is not a substitute for diagnosis or treatment by an optometrist, ophthalmologist or doctor.
- Online vision checks are screening aids, not diagnoses; a normal result does not rule out disease.
- Eye exercises can support comfort and relaxation but do not cure refractive errors or eye diseases.
- Sudden vision changes, eye injuries and severe pain are emergencies.
Information only
The guides, articles, exercises and tools on gozcimnastigi.com are intended to help you understand eye health and have better-informed conversations with eye care professionals. They are general in nature and cannot take into account your medical history, medications, examination findings or individual circumstances. Using the site does not create a doctor-patient relationship, and we do not provide personal medical advice by message.
We follow the guidance of bodies such as the WHO, the American Academy of Ophthalmology, the National Eye Institute and the NHS, as described in our editorial policy. Even so, medical knowledge changes, recommendations may differ between countries, and errors can occur.
Not a substitute for professional diagnosis
Many eye conditions cause no symptoms in their early stages. Glaucoma, for example, can slowly damage the optic nerve without pain or noticeable change in vision until it is advanced, and diabetic retinopathy may be present long before sight is affected. Only a comprehensive eye examination, including tests such as eye pressure measurement and a view of the retina, can detect these problems. Regular examinations remain essential even if our tools give reassuring results. Our guides on eye examinations and how often to have one explain more.
Never stop, start or change a treatment, medication, glasses or contact lens prescription based on our content without consulting a qualified professional.
Vision checks are screening aids
Our interactive tools, such as the visual acuity check, the Amsler grid and colour vision plates, can help you notice possible changes. Their results are affected by screen size and quality, brightness, viewing distance, room lighting and how the test is performed.
| What our vision checks can do | What they cannot do |
|---|---|
| Prompt you to book an examination | Diagnose any eye condition |
| Help you track changes between visits | Measure eye pressure or examine the retina and optic nerve |
| Illustrate how vision is tested | Produce a glasses or contact lens prescription |
| Raise awareness of colour or near vision issues | Rule out disease when the result looks normal |
What eye exercises can and cannot do
Eye exercises and relaxation techniques on the site may help reduce discomfort during long screen sessions, encourage regular breaks and blinking, and help you relax. Some specific exercises are used by professionals to treat certain binocular vision problems such as convergence insufficiency, but this should happen under professional guidance.
Exercises do not cure myopia, hyperopia, astigmatism or presbyopia, and they do not treat cataract, glaucoma, macular degeneration or other eye diseases. They will not replace glasses, contact lenses, medication or surgery. Stop any exercise that causes pain, dizziness, headache or double vision, and talk to a professional if symptoms continue. If you have had recent eye surgery, a retinal problem or another eye condition, ask your eye doctor before starting. More detail is in our article on the evidence behind eye exercises.
Emergency advice
Seek emergency medical care immediately, for example at an emergency department or by calling your local emergency number, if you experience: sudden loss or dimming of vision in one or both eyes; a curtain, shadow or veil across your vision; a sudden shower of new floaters or flashes of light; severe eye pain, especially with redness, headache, nausea or vomiting; sudden double vision; a chemical splash in the eye (rinse immediately with plenty of clean water while getting help); or any penetrating injury or blow to the eye.
Our eye emergencies and first aid guide gives more detail, but it is not a replacement for urgent care. Do not wait for a reply to a message or look for answers online when these symptoms occur.
Children, pregnancy and existing conditions
Children's eyes are still developing, and conditions such as amblyopia respond best to early treatment, so children need examinations by professionals regardless of home test results. If you are pregnant, have diabetes, high blood pressure, a history of eye disease or take medicines that affect the eyes, discuss eye care with your doctor.

Frequently asked questions
Can I use the online vision test instead of seeing an optometrist?
No. Our vision checks are screening aids that may highlight possible problems. They cannot measure eye pressure, examine the retina or produce a prescription, so they never replace a professional examination.
My online test result was normal. Do I still need an eye exam?
Yes. Several serious eye conditions, such as glaucoma, cause no symptoms early on and cannot be detected by screen-based tests. Follow the examination intervals recommended for your age and risk factors.
Can eye exercises improve my prescription?
No. Exercises do not correct refractive errors such as myopia, hyperopia, astigmatism or presbyopia. They may help comfort and relaxation, and some are used under professional guidance for specific binocular vision problems.
What should I do if I suddenly lose vision?
Treat it as an emergency and seek care immediately at an emergency department or by calling your local emergency number. Sudden vision loss can be caused by conditions where every hour counts.
Can I ask you about my symptoms?
We cannot give personal medical advice or diagnoses. Please contact an optometrist, ophthalmologist or your doctor, and seek emergency care for urgent warning signs.
