Contacts are a great option for people with high myopia. Including improved vision quality, greater clarity of vision, and the freedom of not having to wear glasses. Contact lenses also provide additional protection from dirt, dust, pollen, and UV rays, helping to reduce discomfort and irritation.
Contact lenses also tend to be more comfortable and require less maintenance than glasses. As an added benefit, some contact lenses can be worn for up to a month at a time and can be easier to keep clean and sanitary.
The downside to wearing contact lenses if you have high myopia is that you may experience more discomfort than people with lower levels of myopia. Contact lenses can be difficult to keep moist and can cause dryness and irritation if not cared for properly.
Additionally, contact lenses can also be expensive compared to glasses and may require initial fitting and customization. Ultimately, it’s best to consult with an optometrist to determine the best choice when it comes to managing your high myopia.

What prescription is too high for contacts?
Generally, however, the maximum prescription for contacts is typically around -12. 00D or +6. 00D. While some contact lenses may be able to accommodate a stronger prescription, it is best to consult with your optometrist to determine which type of contact lens is best for you and your vision.
In some cases, people with a strong prescription may need to opt for special types of contacts such as hard lenses, hybrid lenses, or even scleral lenses. Your optometrist can help you decide which type of contact lens is the most suitable for your particular prescription.
Additionally, if your prescription is too strong for even the most advanced contact lenses, surgery may be the best way for you to get the clarity of vision you require.
What is the maximum power for contact lenses?
The maximum power for contact lenses will depend on the materials used in the contact lenses and their design. Generally, you can get lenses with an optical power of up to +30. 00D and -20. 00D. This is the maximum power available to be used in contact lenses and will vary between manufacturers.
High powered lenses may also be considered risky to use, as the curvature of the lens means it may not be comfortable or safe to wear. For this reason, it is important to speak with an optometrist to get the right lenses for your individual needs.
Can I wear contacts with a higher prescription?
Yes, you can wear contacts with a higher prescription. Your eye care provider will typically be able to determine what type of contact lenses are best suited for your eyes and your prescription. It is important to carefully follow all instructions provided by your eye care provider when it comes to selecting and wearing contact lenses with a higher prescription.
Depending on the specific prescription strength, your eye care provider may recommend a different type of lens, such as a different base curve or diameter. Additionally, it is important to follow the recommended schedule for replacing your lenses, as this will help ensure that your eyes stay healthy and comfortable.
What is considered legally blind in contacts?
Legally blind is defined in the United States as visual acuity of 20/200 or less with correction (glasses or contacts), or a visual field of less than 20 degrees in your best eye. This means that a person with legally blind vision can only see at 20/200 or worse, even when wearing contacts.
It is important to note that even if a person has contacts that correct their vision to 20/20, they may still have a visual field of less than 20 degrees and be considered legally blind. In addition to visual acuity and visual field, a person must also meet the definition of a “central visual processing impairment”, meaning that the brain is not able to interpret certain visual information.
This may affect a person’s ability to recognize faces and to track objects.
Are contacts worse for your eyes than glasses?
Generally, no – contacts are not worse for your eyes than glasses. However, it is important to note that certain types of contacts can be more damaging to your eyes than glasses if they are not properly cared for and if the contacts are not the right prescription for your vision.
Contacts should be replaced regularly and be prescribed by an eye care specialist to ensure that your sight is optimized.
Contacts may also cause more irritation and dryness due to the fact that they rest directly on the cornea of your eye and can also cause a “corneal scar” if the wearer blinks or rubs their eyes too frequently.
Whereas, with glasses, the lens is a few millimeters away from the cornea. Glasses can be beneficial for some vision correction issues, such as presbyopia or astigmatism.
Ultimately, each person needs to assess their eyesight and lifestyle needs in order to determine which option is the better choice for them. For people who do not have an intensive lifestyle involving sports or water activities, glasses may be the better option for vision correction.
For those with more active lifestyles, contacts may be preferable in order to have unobstructed vision without needing to worry about keeping the glasses in place.
Do your eyes get worse if you don’t wear contacts?
No, not necessarily. Wearing contacts does not directly improve the quality of your eyesight, however with corrective vision treatment, it is possible to improve your vision with or without contacts.
However, it is important to wear contact lenses properly and maintain good hygiene standards to avoid any health issues or potential damage to your eyes. The basic premise of corrective vision treatment is to correct vision defects, not necessarily to protect your eyes against deterioration.
If you do not wear contact lenses, there may be an increase in the rate of deterioration of your eyesight if there is an underlying medical condition, such as glaucoma or cataracts. Additionally, prolonged exposure to computer screens, overexposure to sunlight, and age-related visual changes can also lead to vision changes and even reduced visual acuity.
That being said, regularly visiting an optometrist and receiving regular eye exams can help detect any changes in vision health or vision problems early. On top of that, it is important to maintain good healthy habits, such as eating a balanced diet, wearing sunglasses, and quiting smoking, to preserve your vision.
Can people with astigmatism wear contacts?
Yes, people with astigmatism can wear contacts. Astigmatism is a common condition affecting the shape of the cornea, which is the clear, round dome-shaped structure at the front of your eye. It’s a refractive error, meaning that the eye does not bend light correctly, leading to blurred vision.
In people with astigmatism, the cornea is shaped more like a football instead of a basketball and this causes objects to appear either blurred or stretched out. Fortunately, contacts lenses can be used to treat astigmatism.
There are two types of contact lenses that can be used – soft or rigid gas permeable (RGP) lenses. Soft contact lenses are the most popular, and most people with astigmatism can wear them. The lenses come in different shapes and sizes, which aim to mimic the shape of a healthy cornea.
This helps to correct the distortions caused by astigmatism and improve vision. RGP lenses are also used to treat astigmatism, but they are less commonly used as they can be more difficult to fit. Whether a patient should go with soft or RGP lenses will depend on their individual visual needs and the severity of their astigmatism.
Why would an optometrist say someone Cannot wear contacts?
An optometrist may advise a person not to wear contact lenses for a variety of reasons. Most commonly this is due to the presence of eye conditions or diseases. These include conditions such as dry eye, keratoconus, or eye infection.
Other conditions such as astigmatism, presbyopia (age-related farsightedness), or large pupils can also be a contributing factor. The optometrist may also make the determination to avoid contact lenses because of the patient’s lifestyle factors.
People who swim frequently, take part in contact sports, or conduct laborious activities may be recommended against contact lenses due to the risk of complications. The optometrist may also recommend against contacts if they feel the patient cannot correctly insert, remove and care for them.
This can be determined by administering a contact lens evaluation and teaching session to understand the patient’s ability to properly handle contact lenses. Lastly, some people may have simply poor comfort with contact lenses and optometrists will likely avoid contact lens use if poor comfort is reported.
Can I wear contacts while using steroid eye drops?
The use of steroid eye drops does not necessarily exclude you from wearing contact lenses. You should, however, always check with your doctor or optometrist to make sure that it is safe for you to wear contacts while using steroid drops.
Your optometrist may prescribe special contact lenses to use when using steroid drops. Additionally, they may recommend that you wear your contact lenses less often while using the drops. It is important to regularly clean your contacts and contact lens cases when using steroid eye drops.
Additionally, you should always wait at least 15 minutes after using the drop before applying contact lenses, as the drops may irritate the lens surface. Make sure to closely follow your optometrist’s instructions and contact lens care instructions regarding the use of steroid eye drops.
What is the highest eye prescription?
The highest eye prescription is determined by the amount of near- or farsightedness (refractive error) that a person has in their vision. The most common measurement for this refractive error is known as diopters.
A diopter measures the amount of magnifying power it would take to provide a person with perfect vision at a distance of one meter. The highest level is typically around -20. 00 diopters for nearsightedness and around +20.
00 for farsightedness. While higher levels cannot be accurately measured on an eye chart, there have been cases of people with even higher prescriptions.
What is the highest astigmatism level?
The highest astigmatism level is 6. 00 diopters. Astigmatism is a common vision condition that usually requires corrective lenses. It is caused by an irregularly shaped cornea that makes light rays focus at more than one point on the retina.
As the astigmatism level increases, the number of foci increases and the eye is unable to properly focus on objects. In general, a degree of 1. 00 diopters is considered mild and levels above 3. 00 diopters are considered to be higher than average, while levels beyond 6.
00 diopters are considered severe. In order to diagnose astigmatism, the patient must have a comprehensive eye exam done by an ophthalmologist. Treatment for astigmatism typically includes correction with glasses, contact lenses, or, in some cases laser surgery.
Is my astigmatism prescription too strong?
It is difficult to answer your question without knowing the specifics of your prescription. If you are unsure about your prescription, it is best to consult an eye care professional for a review. They will be able to determine if your astigmatism prescription is too strong based on factors such as the amount of cylinder and axis present in your prescription.
Generally, astigmatism is considered to be within normal limits when the amount of cylinder present is between -0. 5 to -2. 5 diopters. If the amount of cylinder is greater than this, your prescription may be considered to be too strong and could lead to eyestrain and potentially blurred vision if not corrected.
An eye care professional can also recommend the best type of lenses for your prescription and can provide exercises and advice for reducing the symptoms associated with strong astigmatism.
What is considered a serious astigmatism?
A serious astigmatism is considered to be any degree of astigmatism where there is a significant visual impairment. Generally, an astigmatism of greater than 1. 5 diopters is considered to be clinically significant and affects vision.
Symptoms of serious astigmatism can include blurred vision at all distances, distorted images, difficulty seeing at night, eyestrain, fatigue, headaches, squinting and difficulty reading small print.
Because the degree of astigmatism can vary, it is important to get a comprehensive eye exam to determine the degree of astigmatism and the proper corrective lenses or contact lenses to address the symptoms.
Treatment for serious astigmatism typically involves corrective lenses, contact lenses or refractive surgery. Proper diagnosis and treatment for astigmatism can help improve vision and reduce the risk of further eye problems.
What astigmatism is too high for LASIK?
Astigmatism is usually considered too high for LASIK if the level of corneal asymmetry is more than 0. 75 diopter. Generally, people with astigmatism up to 4 diopters may be good candidates for LASIK, although some people with up to 6 diopters may also be treated.
If a person’s astigmatism is above that range, surgeons may recommend a different type of refractive surgery, such as Conductive Keratoplasty (CK) or another type of astigmatic correction surgery. In some cases, intraocular lenses can be used to assist with astigmatic correction after LASIK, but this is typically reserved for those with higher levels of astigmatism.
Ultimately, the best way to determine whether or not a person is a good candidate for LASIK is to have an evaluation with an ophthalmologist to determine the level of corneal asymmetry as well as other factors that might affect the success of the surgery.
