Brief Summary

This is a prospective, randomized, double-blind, parallel, active-controlled, multi-center clinical study. The purpose is to evaluate the safety and effectiveness wearing "DSiHy Silicone Hydrogel Soft Contact Lens". Subjects will be randomized in 1:1 ratio to wear either the investigational device "DSiHy Silicone Hydrogel Soft Contact Lens" or the control device Daily Silicone Hydrogel Contact Lenses(oB)".

Conditions

Myopia; Refractive Errors

Keywords

Outcome Measures

Primary Outcomes (1)

• Visual Correction

  The effectiveness of vision correction is defined by the proportion of subjects whose contact lens corrected visual acuity in both eyes is 1.0 or greater.

  3 months

Secondary Outcomes (2)

• Visual Correction

  1 week, 2 week, 1 month and 2 months

• Change in refraction

  1 week, 2 week, 1 month, 2 months and 3 months

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Must be 18 years of age inclusive
• Beside myopia and astigmatism, subjects with normal eyes and are not using any ocular medications (excluding ocular lubricants and artificial tears)
• Best spectacle corrected visual acuity greater than or equal to 1.0 for both eyes
• With +8.00D \~ -12.00 D spherical component myopia, and ≤1.00 astigmatism (based on manifest refraction measurements)
• Have worn soft contact lens for at least 2 month prior to the study
• Willing to comply with the required wearing time
• Agree to comply with all study procedures, sign and date the informed consent form before starting the clinical study

You may not qualify if:

• Anterior segment infection, inflammation or abnormality
• Any active ocular disease that would affect contact lens wear or vision (such as acute and subacute inflammation of the anterior chamber of the eye, eye infection, uveitis, serious palpebral abnormality, corneal hypoesthesia, corneal epithelium abrasion, dry eye and tear duct defection, ocular allergies, highly suspected glaucoma) upon evaluation by the investigators or slit lamp findings
• Currently using systemic or ocular medications that would contraindicate contact lens wear (such as glaucoma eye drops, steroid anti-inflammatory drops, eye ointments, eye gels and other eye medicines)
• History of herpetic keratitis
• History of refractive surgery, keratoconus or irregular cornea
• A pathologically dry eye (Schirmer test 1 \<5 mm)
• Have participated in any contact lens or contact lens care product clinical trials within the previous 1 month (excluding questionnaire types and specimen collection)
• Currently pregnant, lactating, or planning to be pregnant during the trial
• Have experienced discomfort when wearing silicone hydrogel contact lens, or a known allergy to hyaluronic acid and sodium alginate
• Corrected visual acuity in either eye does not reach 1.0 when wearing the trial lens
• Subjects who are judged by the investigators as unsuitable for the study
